I'm about to start building my crack, and was wondering if it's okay to paint the visible parts of the screws and washers that attach the transformer and tube sockets. Especially the ones on the transformer. I don't want to interfere with any of the grounding. I'm wondering about painting them before assembly, so the entire washer and screw head would be painted.
I couldn't find many previous posts mentioning doing this, and any that were similar seemed to be for an older revision of the crack.
Thanks for any advice!
