In the thread below, I picture the cool new clear pickguard I made for my T-bird. Just days later I notice something strange. Looked like something might have been happening to the guitar's finish around the screw holes of the new pickguard. Anyway, the pg is polycarbonate plastic that evidently reacts somehow with nitrocellulose.
No serious damage was done. The finish only got a little dull for a distance of about 1/8 inch all around the screw holes, but given more time the lacquer might have bubbled or liquified or something. So I can't use polycarbonate. The trade name is Lexan, which is probably another name for Plexiglass.
Now I'll probably try making one out of true pickguard material, and I think black. Black would look good with all the black hardware. BTW, I love this bass. Check out the new clear pickguard on my Gibson T-Bird
