The old saying practice, practice really applys when painting. Metallic colors are hard to get uniform coverage, and the higher the metallic the harder it is. The condition your refering to is called metallic sag/shadow. Now is the time to "buddy" up with a painter, maybe he will teach/help you out. All rules of painting need to followed to the letter. The "mix" "spray" "pressure" "stroke" "equipment". A cheap paint gun will not get the job done and an expensive one won't make a painter out of you. See the tech tips and practice on some old parts. Painting is a learned "skill". You might want to reconsider using "clear" coat, but then you have to deal with catalyst/hardners and the environment. Theres not enough space here to cover all, just do your homework, seek advise, ask for help and be safe!
