Re: Painting plastics
Ok, I found a little article on the net:
"Painting plastic s really not much different than metal.
1. Remove all decals (Tank's decal is under clear-coat, so it is more
2. Sand all surfaces with appropriate grit paper to remove gouges. I use a
4 inch palm sander for most of the rough work starting with 180 - 320 grit
depending on how deep I need to go. End all sanding work with 400 grit wet
sand. NOTE: Use 600 grit between layers of paint if needed.
3. Chances are if you think you need filler you might not as you can cut
down the plastic more than you think. Be careful and work slow letting the
paper do the cutting. If you need to fill, try not to use Bondo. The
vibration inherit in cycling will tend to promote cracking (under the
paint) which ruins an otherwise good paint job. Use spot putty instead.
Build up many light layers instead of one heavy one. Spot putty sand off
real easily so you might have to do it a couple of times for best results.
4. When painting plastic, you do not need to remove all the paint but you
need to seal the OEM paint and plastic. I used an epoxy based etching
primer/sealer under my paintwork. Ask your paint store for recommendation
depending on what "system" you will be using.
5. Go to a professional automotive paint store and purchasing professional
quality paint. Use paint that you need to mix with hardeners/reducers etc.
like Acrylic Enamel or Acrylic Urethane from Dupont or PPG. Use a high
quality spray gun and air compressor as opposed to shooting on a few layers
of rattle can (Krylon) paint. Acrylic Enamel or Acrylic Urethane are
"Soft" paint and will tend to not chip or crack and are more flexible to
deal with the bending of the
plastic. It varies depending upon the paint type and maker so your best
bet is to consult with whomever you purchase your paint from.
6. Paint in a "dust free" environment. Either rent a booth or hang plastic
on walls and ceiling. Get a high volume fan for exhausting overspray dust.
I use a dryer filter in front of the fan is used to catch as must dust as
possible if you are using your garage to paint.
7. ALWAYS USE A TOP QUALITY RESPIRATOR MASK and eye protection. Use
surgical rubber gloves for final prep and paint. It keeps your hands clean
and more importantly keeps your skin oils of the panels.
8. On that note always wipe off the panels with a wax/grease remover just
prior to painting and use a tack cloth to get rid of any lint/debri."
The only thing that I am wondering about now is whay about when the plastic IS the color???
