I made a clear acrylic pickguard that I want to color the back of with metallic paint. It will be in contact with the clear nitrocellulose covered body. I'm thinking I'm going to have a problem either in the short term or long term, with the pickguard paint chipping off or worse, reacting with the body lacquer. I'm thinking of covering the acrylic metallic paint on the pickguard with clear nitro as a protective measure, but I think they'll still stick. Another method is making a paper or copper foil gasket to fit between the body and pickguard. Never had problems with bakelite, but then again I don't cover the backside of those kinds of pickguards. Dunno if the nitro will be compatible with the metallic paint, but that's why i'm running some tests first. Anyone have any experience with this situation?
