I don't mean to keep posting, but I teach a composites class and I am just trying to help by throwing out some different ideas.

We use Meguires Molds release wax which is very paint friendly and after waxing the mold about seven times, we directly paint the mold with Lustercoat, or some other laquer based paint. Your first couple of pieces might not be perfect, so I would wax the mold a few extra times, but the more you use the mold the better it will release.

We let the painted mold cure for at least two days, then do our layup by painting on a thin layer of epoxy then laying our cloth down, pushing the cloth gently into the epoxy with a small brush and getting out any air pockets. When the piece is cured and popped out of the mold, we have a perfectly painted piece with NO pinholes.

Just a thought,
