The Perfect Paint Job
Our goal is to accomplish a paint job that has a
strong foundation, maximum gloss and will last for many years. This type of
for the everyday production body shop but it will serve you when you do your next
restoration or a street rod job. We are going with the assumption that the
metal or fiberglass has been stripped of all paint.
metals and aluminum should have 80 grit DA scratches.
Bare metal is always best cleaned with #700-1
Waterborne Wax and Grease Remover then let it set 30-60 minutes before
applying the epoxy!
After first reading our Epoxy Tech Sheet mix
enough #6600 series epoxy to spray two wet coats over the entire car. Spray
one wet coat and let flash about 30 minutes then apply a second wet coat.
Let the epoxy set overnight then apply body filler, fiberglass filler or
glazing putty over the epoxy. It is
to sand the epoxy before applying the fillers (within the first 7 days of spraying epoxy) as
they will bite into the epoxy and feather great. When you have finished
sanding all of the bodywork you are likely to have some bare metal spots
from sanding. Spray one wet coat of epoxy over all filler spots and over
any bare metal spots. Now let the vehicle set overnight.
The next day you can start spraying the 2K
Primer over the epoxy. Once again, it is
not necessary to
scuff or sand the epoxy before applying primer. The most important thing to remember at this
point is spray one wet coat of primer and let it set for 10 minutes before
applying the second coat. Follow this procedure between coats of 2K Primer.
This step when abused messes up more paint finishes than anything else!
When all of the primer blocking and any
necessary primer repairs are finished itís always best to use the epoxy as a
sealer. Mix up enough epoxy to go around the car with one wet coat and
adding a double shot glass of SPI #885 Urethane Reducer per quart. Let the
epoxy set for 30 minutes. Stir one more time and strain. Spray one full wet
coat of epoxy over the entire car. The epoxy should set for 2 hours before
spraying basecoat or the next option is let it set over night and wet sand
the epoxy with 400-800 then spray the base.
Next to rushing the 2K Primer rushing the
basecoat is the second cause for the final gloss and depth of a paint job to
look bad. Itís very important to use the slowest urethane reducer in your
basecoat that you can get away with regardless of outside temperature. Just
allow enough extra time for the basecoat to flash off and dry. The
difference between a very slow grade and medium grade reducer will show up
in the final gloss. The slower grade reducer also has better solvency and
will give you far better adhesion. Spray the first coat and let it totally
dry before spraying the second coat. Itís best to wait 30-45 minutes
between coats of base.
basecoat isnít perfect:
After two coats of base the vehicle should set overnight then do any minor
wet sanding with 800-1500 grit sandpaper to remove any orange peel or trash.
Apply the next two coats with 45 minutes of flash time in between coats.
Some colors will require additional coats. If this is the case, again, wait
45 minutes between coats.
basecoat set overnight.
A word of
caution: There are 2-4 basecoats types that cannot be sanded or you will
lose adhesion so avoid those basecoats. Check with your basecoat
The following day tack off the vehicle then
apply a wet coat of SPI Universal Clear and let the first coat of clear set
Spray the second wet coat of clear and let it
set 30 minutes. Let the clear set for 30 minutes before applying each
additional coat as well.
Then proceed with normal wet sanding and buffing
when you are ready.
multiple coats of clear over multiple days:
From two days to two weeks after the job has
been completed, wet sand the clear with 400-800 grit sandpaper to block out
any orange peel or dirt. After wet sanding let the car set in sun for a day
before remasking and degreasing then apply a wet coat of clear. Let the
clear flash 30 minutes. Apply a second coat of clear, then 30 minutes later
apply a third coat of clear.
Let the vehicle set two or three days in the sun
to help to get all of the solvents out and settle the paint job. If any wet
sanding is required before buffing sand with 1500 grit sandpaper then set
the vehicle in sun for two to three hours. Bring the car back into the shop
and allow it cool to room temperature then buff.
If you follow these directions you will have a
durable long lasting paint job with maximum depth and gloss over a solid
wax a paint job applied this way for at least 90 days. This also depends on
the amount of sunlight the car has been exposed to in the meantime so feel
free to call for advice.
