I have painted a few helmets and bikes and I am in search of the best masking film for detailed graphics and murals on all of these curved and rounded surfaces that all these helmets and tanks and fenders have. I do a lot of drawing and cutting on tape that has been layed on the helmets, tanks and fenders. I guess the designers don't think about us..the artists when they design these things If the spray on material is used, can you use a regular gravity feed HVLP or siphon detail gun gun?
