Painting plastic can be very difficult as you know. You say you
used primer paint; for plastic I never use primer, I use Adhesion Promoter.
Adhesion Promoter is mostly a solvent that softens the plastic so the paint
will bit into the surface. Usually the biggest problem with plastic is
getting it clean enough to paint; I use an automotive type silicone remover/
cleaner product. Sometimes you have to warm the plastic up a little so
that release agents or whatever is in the plastic will come to the surface
so you can clean it off.
Since you have already painted the part you might just want to wet
sand it smooth and shot it again. Any painting is a bit of an art form to
get a smooth shiny surface; temperature and humidity are the big factors.
You also have to be careful not to put any fingerprints on the parts. Many
times I will put on a nitrile glove and hold the part in my fingers to paint
them.
If you are shooting with an aerosol can one really big factor is the
nozzle on the can. I like the nozzles with the fan pattern you can turn
from vertical to horizontal and I keep extra clean nozzles handy in case one
clogs up. You can soak a clogged nozzle in a little bit of lacquer thinner
to clean it out.
Good luck with your painting.

Folks,
I'm finishing up the restoration of my steering wheel and have begun working
on the steering column pieces. Originally, I just cleaned-up and polished
the bakelite which had browned over time as usual. However, after restoring
the hub of the steering wheel and repainting it black, I decided to do the
same to the column pieces. I've had trouble painting bakelite in the past,
so I took particular care in cleaning the pieces with acetone before
applying primer. Everything went fine until I sprayed the black on the parts
and ended up with an orange peel mess. Anyone have any ideas as to why this
happens and what can be done to prevent it?
Thanks,
Joe Parlanti
