I'd like to buy a black Nikon FG to shoot my one Leica R lens, but the prices are just crazy. A working silver one can be found for half the price, so you can see where I'm going w/ this. I have acrylic paints, and since these are plastic bodies (around a metal frame, I think) ,I figured that a plastic sort of paint might work. Would this just flake off even after roughing up the old surface w/ sandpaper or steel wool? Maybe put a coat of clear over the paint to try and protect it? If it has to be painted, I have this crazy idea to paint it like a Grateful Dead T-shirt.
