I usualy paint my canopys on my airplanes black, Im not a big fan of using pilots, anyway this time I thought Id use a metalic silver on my latest kit. I was always told to paint the inside of the canopy, so that what i do, well this time when I scuffed the surface with some sand paper I apparently scuffed a little to deep because when i applied the paint it didn't fill the sanding marks, and from the outside of the canopy it looks really bad. My question is should I replace the canopy or will it be ok to paint the outside? Any suggestions would be greatly appriceated!
