Before I get everything installed and riveted, I thought it would be a good idea to paint those surfaces which will be partially inaccessible once assembled like the hinged control surfaces. These don't have to be real pretty, so I disassembled, cleaned, scuffed, and primed and sprayed with rattle can self-etching primer and white automotive paint. I'm doing the same with the bubble door frames since they will be hard to get to once the plexiglass is riveted.
