We're working on some semi-OT projects, bicycles, and we want to shoot them with a metalflake paint job. I've never shot flake before so this is all new to me. I know you need to carry it in a mid-clear and then completely clear it over for longevity, but other than that I don't know which tip to use, how much I'm going to need, etc. Are there brands that are preferred over others? Should I steer clear of certain types of flake? Any and all advice is appreciated. Thanks!
