From
a man that knows his stuff (Kinda)
Panhead's
Safety
first!
Whenever
you are dealing with chemicals, you had better
be paying attention. You think Popeye has that
squint because of spinach? Uh --uh Bucko, it's
that varnish he's using! Nobody knows what caused
his genetically estranged forearms tho.......(Uut,
tut tut tut tut!)
Eye
protection is a given. But, so many folks forget
about the LUNGS! Well, I will mention it once
here. Protect those suckers! Smoking is goofy
enough, but catalyzed products are really strange.
There
is nothing like the kids at Christmas saying "Do
it again Dad!", when you cough up a loogie the
size of a small jap import, representing the last
paint job you did, and it lands on the tree like
some nativity scene and it sparkles to boot! If
you do it for a living, or even for a bunch of
friends, please invest in a fresh air system,
or at LEAST a decent respirator. Is a few hunert
bucks to much to pay for the rest of your weasely
life? Knowing how to use the tools you buy is
also a plus. "Tim the tool man Taylor" is NOT
the show or the man to pay homage too at this
point.
"Who
said that?"
Whoever
said that 90 % of the paint job is the preparation,
is a foul mouth S.O.B that deserves to have his
ass handed to him, carved in various ways, served
on a lazy susan *as* his birthday dinner with
a onion wedged up the orifice of your choosing!
It is 97 percent if not more!
Look,
any body can pull the trigger of a spray gun.
But it is a PAINTER that knows what to do when
things go goofy, or better yet, how to prevent
the problems in the first place. A great painter
never has problems. Period. I happen to be a pretty
decent painter. Sometimes I get goofy, and slack
on the basics. However, I feel competent enough
to teach, and sober enough to give CORRECT answers
to any questions you feel like putting my way.
So,
without further ado, lets have a look at ....
The
Basics! (and why Clean is good!)
I
ain't gonna get into body work here.
You
had better know how to get that done or, do it
your selves by now eh?**
Why
paint crumpled tin I say.
First!
The part you are about to paint (or even do work
on) MUST BE CLEAN! The best way to prep before
paint is to use a wax and grease remover. Actually,
this should be the first thing you should use
before doing any work on a project.
(I
am going to assume all that are reading this web
sight can read instructions plainly printed on
the cans of stuff they buy!)
We
are also going to assume that the object you are
about to paint is a piece of metal/plastic or
whatever, and it is in good shape and ready for.............color!
When
deciding on what you want to do as the paint job,
color, paint scheme, etc., you first must know
by now if what you are painting is ready to except
the paint...right? Right. If you have a new piece
of factory tin with a stable paint job on it already,
it will most likely take hold of a new paint job,
and it will last many, many years.
But,
if the paint job you are planning to do is a custom....like
a Candy or multi color extravaganza with clear
and decals, you had better consider stripping
it first! High levels of paint build do not a
long a lasting job make. So, if the OEM paint
is ok, and all we want to do is apply a simple
re-coat of color, we need to first use a Wax
'n grease remover, then wet sand thoroughly
with 400/600 grit paper. A cap full of Ivory
dish washing liquid in a gallon of water really
helps to prevent the paper from clogging and it
helps remove more contaminants. If you are doing
many colors, or candy’s, or the tank has a lot
of paint on it, it should be stripped.
So,
if needed we must ....
STRIP
THAT SUCKER!
This
is so easy. It is also so messy. Basically you
buy the stripper, you slosh it on, you wait, you
scrape off the crap...
Voila!
Done!
Right?
WRONG!
If
it were that easy, any body could do it.
Let's
assume you HATE the paint that is on it, and you
know you have to yank it off to repaint. OK. "What
now Uncle Panny?" you ask. Simple my little love
muffins. After we assume yet again that the tin
is sound, pressure tested,(in the case of a gas
tank) and ready otherwise, we cover those openings
with DUCT TAPE. We drape paper, Glad bags, the
ex-wife's Persian rug on the floor, and THEN slosh
on the BEST F*%$# PAINT STRIPPER WE CAN AFFORD,
and let it sit.
(Hint:
Any good paint stripper works in these two ways;
1.
by the obvious chemical reaction
(To
help speed up this process, Gouge the paint surface
deeply in a tic tac toe manner to "open up" the
surface of the old paint. Use a screw driver,
awl, anything pointy and hard, to get to the substrate.)
2.
by the gasses that creep into AND under the old
paint!
This
works GREAT if it is ultra hot outside. (Tee hee.
I really don't know why nobody knows this, and NO
the stuff will NOT eat the plastic garbage bags...rubbish!.)
This is the cool part. The stripper does the work
for you.! Sometimes it might need several coats
of stripper depending what type you buy, and the
amount of paint you have on it. Regardless, there
is plenty of beer drinking time. This is NOT a time
to push the chemicals into doing something they
won't do by them selves.
Don't
hurry...be happy.
Put
on a coat. .wait a beer.
Scrape
off the shit you think is ugly, and put on a second
coat.
Have
another beer.
Before
you know it, you're drunk and the paint is all
gone!
After
all the paint you can remove is gone by chemical,
then we must either by hand (eww) or DA sand off
ANY and ALL traces of paint and filler that the
stripper didn't remove. If one tiny spec is left
on, you're really going to regret it. I prefer
80 grit on the ol' air sander. If there are dents
and bodywork to do, attack those areas with no
finer than a 24 grit grinder. As to the use of
a DA sander, I prefer the ones that have a "lock-up"
feature that allows you to use it as a "grinder"
…sorta. With 80 grit "3-M Green Corp." DA paper,
in a locked mode on the ol DA, this really removes
everything in a blissful hurry! You must use it
right though! Long straight sweeps with much overlap,
using moderately forceful pressure to keep the
DA spinning fast and, not to much to cause excessive
heat on the surface.
Prep
it! Cleaning, and other things you MUST KNOW!
After
most of the paint is deleted from the object by
any kind of stripper, and you sand , grind away
all the rest (paint, bondo, whatever) you should
then Neutralize it with water first. (remember
those instructions on the can?) Then, we should
scrub down with a scotch-brite pad, and lacquer
thinner, (NEVER use steel wool which contains
a lot of oil) and remove all traces of shmutz
and residues. (I hope it's now not to late to
mention that you should stop eating Kentucky fried
chicken, Taco Bell, or ANY OTHER greasy kinda
food) next you should follow with a good wax and
grease remover like Sikkens, or what ever you
like best.
Do
NOT allow yourself or you friends to touch it
now! Even the natural oils from your skin can
cause big problems later!
You
should now have a PERFECTLY clean shiny piece
of metal. This is good!
Now
is the time to do body work if needed. Repeat
the wax and grease remover process EVERY TIME
you complete a step!
Get
it primed as soon as you can! Bare metal does
not like the atmosphere. Mother Nature is indeed
a fickle wench when it comes to bare, shiny, metallic
things.
This
is good painting practice. Anybody that tells
you otherwise, should be kicked in the groin....Hard!
Primers,
and what they mean to you!
This
causes a lot of confusion, and I don't see why.
A
primer is a coating that is designed to
adhere like a bandit to the substrate. This is
also a product that does NOT GET SANDED! It is
used to adhere to the object in question so that
the next product can go on top.(like a primer
/surfacer) If you have aluminum, you need a primer
that is designed for aluminum and the following
coats of whatever. If it is plastic, then the
same thing applies. This is why I like PPG's DP-40(and
the various other numbers ) from PPG/Ditzler.
It works on ALL substrates, and can be top coated
with most anything. It is a catalyzed product...(very
deadly when introduced to your lungs, or when
mixed with anything and ice).
Next
is a PRIMER /SURFACER! This is the shit
you sand!
Some
primer/surfacers can go over most anything also,
providing you treat the substrate first with more
chemicals, like an acid wash.
So,
first we prime, then we place on a primer/surfacer.
The
reason for the surfacer is so that we can fill
in imperfections and eventually have a surface
that is smooth as a 6 year old girls butt....or
so I hear.
This
is where the work comes in...and the talent ...and
your patience. Above all else, patience!
Priming
with the surfacer, allowing for proper dry/cure
time, block sanding, repriming, etc. etc. etc.,
until it is PERFECT, is indeed the key!
If
you have a lumpy pitted nasty surface now, and paint
on top of it, you will indeed have a shiny, lumpy,
pitted and nasty surface when you are done. Paint
is expensive. Don't fuck up now!
This
is yet again why I love DP-40. It acts perfectly
as a primer AND a sealer! Way cool. The purpose
of the sealer is to .....seal the primer.
This
is the last step before actually dipping it into
the bucket of paint.
What
I like to do is this: After I get the "fill" primer/surfacer
on (the first coats of it) I like to block sand
with 220 wet and dry. This is a course sandpaper,
but the idea is that we want to knock down and
*level* the surface.
If
I sand to much in an area and go through to the
fill primer and see the first primer or the steel
underneath, I stop sanding there. You should too.
Apply more fill primer and do it again. If you
are satisfied that it is all perfectly straight
and you do see tiny little areas (like an edge
here or there) don't panic. This is where the
final coat should be sanded with maybe 400/and
finer grit papers. Then apply the primer sealer.
DP-40 fills in 360 sanding scratches very well.
Sanding!
(Aka "The WORK!
or
how to get those nifty lookin Popeye forearms)
......tattoo's optional.
The
sanding is the fun, joy, talent and hard part.
This
is where you will need stamina and plenty of liquids.
This
is where you will see the final product..or how
it comes out.
If
you do well here, you will have a great final
result. If you don't, you will know what I mean
by the saying, "Trying to make Ice cream out of
shit".
When
Working with "nekid" metal I think that
there is nothing better than 80 Grit paper.
Again,
I really think that this sorta thing must be one
with air powered tools. Nothing beats the efficiency
of these. This is why all Body Shop people use
them.
The
best way to use this grit of paper is with what
they (we) call a DA sander.
I
prefer the type that can "lock" as opposed to
the type that can just buzz around.
The
key to GOOD sanding is to be able to whack down
the surface in a hurry without excessive heat
build up. Heat
is NOT our friend...yet.
Quick
cutting ("the whack") levels the surface in a
hurry. This is what we want. On metal, we want
to rid the surface of the stuff we don't want
with out heat build-up. Otherwise we will warp
the tin, destroy the tool and waste the sand paper!
For
a piece of metal that needs NO body work, 80 grit
is wonderful. For those areas that "need" body
work and the fillers used, these areas will NEED
no less than a 24 grit "bite". I like 16 for the
mud areas. When sanding and finishing the plastic
filler..(Bondo™) it should be done with
care. There should be a nice surrounding area
BEYOND the filler with 16/24 grit. The filler
should be shaped with a "cheese grater" and sorta
final shaped with 24 grit using a block or whatever.
The shape must be right. After the shape of the
filler is done right, I like to use a polyester
"Glazing" puttys, and finish with...80 Grit!.
This is when I use and apply the primers, and
the primer surfacers. When I am ready to sand
the primer surfacer, I use 180 or 220 wet/dry
to level the surface.
I
also use a "guide coat".
When
the Primer surfacer is applied, I lightly spray
a mist coat of contrasting color over the surfacer.
This "guide coat" seeps into the sand scratches
and low parts of the object, and allows you to
see very clearly any woopies or dents, or deep
scratches. You should use this method if you have
poor eyesight....or if you are lazy.
I
like using 220 grit wet and dry on the primer/surfacers.
It knocks it down FAST and it levels. Then, if I
have more room for more sanding, I will re-sand
and finish with 400 wet/dry. If I need to, I will
re-prime so I can do the final primer sanding with
400.
When
wet sanding, I always add a few drops of good
ol IVORY (or whatever) dishwashing liquid soap.
One, this helps keep the paper from glogging and
two, it also rids the surface of those nasty oils
and goo.
Once
I have the final prime sanded with 400 grit, I
can apply a sealer...and then paint!
After
the paint is all done, I like to sand it again!
(I am a glutton for punishment) But, I now use
1000 grit..WET! With soap. I wait a day or two
and sand it down to a PERFECT satin finish. Be
aware that the water must be HYPER clean!
One
piece of grit in it can ruin your day! After the
sanding with 1K , I go back over it with 1200
to 1500 grit. This is when I do the polishing.
Getting
ready for the paint! (Oh joy!)
Lots
of primer surfacers on the market have what they
call a "case hardening" date. Usually, this is
just for those yucky lacquer based primer/surfacers.
After a week or so "they" don't like to accept
top coats. The reason being, they get too hard
on the surface which doesn't allow good chemical
bonding with the next things that get dumped on
top.
This
is why one should not put off too long, work as
quickly as possible, and use the best materials...like
me.
After
you are satisfied with the results of bodywork
and finish priming, you should use that last "primer/sealer"
no longer then 12 hours before you are going to
actually paint. This still allows you to lightly
"nib" the surface of bug parts, cracker crumbs,
dirt, dust , what have you.
Remember...use
WAX 'N GREASE REMOVER in between all steps!
When
you have everything ready and sealed, dust tacked
off, it is now time to get your paint mixed! When
masking the parts, it is very important to use
the best tape you can. 3-M's automotive
grade is the only choice for me. It should be
the only choice for you also. The cheap stuff
found at Safeway or the local Joes hardware store
will not stick well...until it gets either wet
or gets paint on it.....Then you can't get the
crap off! For two tone overlays, again use the
3-M plastic "Fine-Line" tape to separate the colors.
Works great. It leaves a wonderful crisp, fine
edge that a paper based tape can’t.
The
paint.
Yes,
I prefer products made by PPG.
Deltron,
while expensive, is great to use by beginners
and, professionals alike. It drys VERY fast and
gives the best Gosh darn results. They make many
other types too, but I ain't gonna get into it
here**.
If
you don't have a compressor, stop now. (I ain't
even gonna ask how you put the primer on) Spray
guns! Wow. Personal choice!
However,
it MUST BE very clean and maintained.
Never
painted before? Practice on the trashcans, mailbox,
the neighbor's car, whatever. Just remember to
be deliberate, but careful.
Don't
rush, allow dry time between those coats.
Do
NOT try to do a Candy color your first time out!
That
involves a few pages all to itself.
Black
is really the easiest color to shoot (also the
hardest to prep for 'though) and white, to me,
is the toughest to shoot.
What
we want is coverage plus extra to play around
with.
We
don't want a thousand coats of paint. Why? It'll
never dry, we also don't want too few.
We
do want adhesion and longevity. Three coats is
perfect.
I
normally apply 4 to 5….Why? Because I wait for
the paint to dry a day or two, then I wet/sand
with 1000 grit and buff to a luster that will
make you blind.….leaving three coats!
You
must have plenty of light and plenty of ventilation!.
You can see what you are doing, and you won't die!
It
should also be warm where you are doing it. Anything
colder than 65 degrees, and you're going to have
a very pretty floor. Because that's where the
paint will run to. It also will not cure right.
When
putting on the first coats of paint, be aware
that if anything is going to go wrong, it will
most likely happen on the first coat! This is
why the FIRST coat should be a very light but
even coat of paint. If things like "Fisheyes"
or "lifting" appear now, then pack it up. You
did something VERY wrong. But, don’t panic….it’s
still savable….we hope.
Other
things!
They
make so many products that add to the brilliance
of paint and the care thereof, as to make your
head spin. Kinda like NetscapeÓplugins.
Some of them suck, (like NetscapeÓplugins),
but most just need to be known they either exist,
or be taught how to use them. And I will mention
them as this page grows, or as questions arise.
I
have ALL the answers.
Sorta
Buffin'-n-waxin'-n-other
shine inducing things
If
you laid on the paint and you are not to satisfied
with the gloss due to things like "Orange Peel"
or maybe the spittle from your mouth got on it
because you were drooling on it because you pulled
off a KILLER JOB, or maybe even some dust specks
here and there….DON"T WORRY! If the color or final
coats are OK, then maybe it just needs a wee tad
of "rubbing out". This too is easy…but.. it takes
practice. That’s why I always say to put on a
few extra coats of paint so you can "play".
This
is dangerous for all those that have never wanted
to get there nails dirty, or have never operated
a power tool before. Only through experience can
one truly know how much paint one has to "play
with".
Basically,
One coat of paint can achieve .5 (or more) mils
of paint. (a .mil is basically the thickness of
a piece of decent paper) This of course depends
on your spray gun, and the paint, and many other
factors. If one uses "shake an shoots" (Spray
cans) you will NEVER achieve any decent film build
, let alone a film build made worth a hoot. But
anyway.... One has to be able to use 1000 grit
(or finer) wet and dry sandpaper (with a wee tad
of Ivory to prevent clogging) and achieve a PERFECTLY
SMOOTH satin finish. (WARNING! DON’T SAND NEAR
or on THE EDGES!!!!…..The buffing will take care
of those all by its self!!)
Then,
we must be able to use a rather good rubbing compound
(I suggest PPG DXR- 65) to achieve the first initial
gloss, using a 9" wheel on a SOIX buffer, or equivalent.
Do
NOT try to do stuff with a Black-n-Decker-pecker-wrecker
on a drill . . . I will warn you only once . .
.machine speed must be around 1100 or less RPM.
Anything
faster will BURN the paint in the hands of the
inexperienced muffin head….this is bad.
Once
the first initial shine is achieved, then go to
the next step . . . a finer compound and a finer
pad. I hate 3-M products as a whole but . . . "Perfect-it
II" is a superb product that will really knock down
the major "initial rubbing swirls" that a course
compound will leave.
We
also need to know about the different "pads" used
to rub out things.
(I
told you this shit gets involved!)
One
type of rubbing pad (heavy wool) is used to "cut'"
the finish. Used with cutting compounds.
Usually
white and very much like the real sheep. Fluffy
and thick.
The
next type is a lambs wool pad, (usually yellow
and very fine) used to apply compounds like "Perfect-it-II"
(or other microfine products) used to whack away
(or fill) heavy swirl marks, and obliterate fine
scritchy scratches. "Liquid Ebony" is also a nice
product, but does nothing but FILL, and does not
eliminate any problems.
Are
you with me so far?
Ok.
The
use of these products is essential for any classy
looking job. It is the polishing that separates
the men from the boys. Think about it: Lacquer,
while very beautiful, dries flat. It is the RUBBING
that gives it its final glory…a glory that doesn’t
last anyway…but it sure looks bitchen! A urethane
will have the exact same results if given the
same love, plus last longer then you do and, be
extremely chemical resistant to boot!
"Fisheyes",
or "Why is my paint job looking at me?"
Fisheyes
are a "thing that happens" when a painter is painting,
and the paint "coagulates" in spots. This only
happens when poor preparation is evident, or someone
is using a silicone based wax (or ARMORALL) within
a 100 mile radius.
Greasy
fingered idjuts touching the product to be painted
also cause this.
There
are indeed products that make the paint less susceptible
to it, (SmoothyÓ) but this never is an excuse
to forget about good painting practices.
To
eliminate "fisheyes", is to not have the cause
of them around in the first place - duh!
But
as we all know, "shit happens".
What
do you do?
Easy.
There
are products that you can add to the paint, to
"help" eliminate the problem from spreading further.
Yes, these are called "fish eye eliminators".
There is indeed a product called "SmoothyÓand
SmoothyIIÓ". These are f*cked! Buy the
"Eliminator" for the paint you are using.....(IMHO,
the only decent fish-eye, degradent for use in
ALL paints is the one made by PPG)
Unfortunately,
adding any kind of fish eye remover to the paint
also causes orange peel. It's a give and kinda
take thing. This is why I stress proper cleaning
so you don't have to add this crap to begin with.
Those that use shake'n'shoot -spray cans, do NOT
have this option.
In
the event of a major Tuna-eye attack, the best
thing to do is to put the gun down! Let the surface
dry, and sand it out smooth.
Then,
reapply the color or clear with the smallest amount
of "eliminator" as possible to get the job done.
Do
you see "fisheye" starting?
If
so, the best thing to do is to apply "piss coats"
one at a time. Light mist coats to seal. Then
apply heavier, as you can.
Runs,
and why it's not just a race of the paint!
If
you get runs in the paint , it means one of two
things.
1)
You lack experience...you're doing too much...too
soon!
2)
It's way to friggen' cold, which means you lack
the knowledge . . . (see #1)
Here
is the Cure!
1)
Don't be squirtin' in Temps less then 70 degrees!
2)
Consider one coat at a time, and do not try
to finish the "job" in ten minutes.
3)
You can read. You are supposed to know what
temperature grade thinner to use at the moment.
This is why all manufactures make several types
of reducers and thinners to make your painting
job a breeze ,and get the desired results.
Adhesion,
and why you need a better glue.
There
is no reason for lack of adhesion of the paint
- unless you were lazy in the prep and sanding
tech-neeks!
Here
is a great run down for the perfect job! First
we consider we have a piece of metal (or whatever)
to paint. I will consider it is good ol American
Steel, stripped of all old paint and debris....an
NO BODY WORK needed!
1)
The piece of steel in question will be cleaned,
washed, and "finished" with nothing less then
80 grit paper. Wax and grease remover usage is
a given.
2)
The correct primer will be used, followed by
primer surfacers. Final sanding should and WILL
be done according to common sense and labels
put forth on the top coat instructions. Final
sanding of the primer surfacer will be done
with NO LESS then the grit of 400...preferably
600.....wet and dry.
3)
The proper sealer will be used, and the color
coat will be applied correctly.
3.5)
Clears (if needed) will also be applied in the
SAME FASHION...correctly.
4)
Proper dry times and TEMPERATURE WILL be understood
and absorbed in your brain, so that you can
do whatever else needs to be done...like buffing-polishing
etc..
5)
you will abide by all rules of hyper-cleanliness
so that you do NOT have to add foolish additives
to paint to counter act your mistakes later
on!
Problems
/ warranties
and
why didn't you come to me in the first bloody
place?
I
really don't know. I don't have any problems . .
. with the paint or customers anyway.
I
like it when potential customers bombard me with
questions. I feel that I can answer them in a
way that satisfies them several ways.
1.
with the info they need, and
2.
with a wee tad of dry humor intermixed to keep
them happy and informed. I never lie, and I
feel I can give them the answers they need so
they can be assured that they will get the best
job they can get for the hard earned money they
are going to put out for a paint job....even
if its NOT me that is going to be doing it.
When
people *do* come to me for a final product, they
are given a "life time" gar-un-tee
against any type of paint failure, for as long as
they (the original buyer of my services) owns the
product. This of course does not include things
like the paint chipping off when a 1955 Buick RoadMaster
hits you head-on. Things like that, I would consider
abuse.
Also,
things like gas tank leaks will just make me laugh
and hang up the phone.
