man, looks sweet as is . when in doubt don't. spray can paint ( krylon ) ( rustolium ) balls up when U try to wet sand it and your job would be trashed. Using spray can paint shoot your color coats ,let each coat tack up then shoot clear coats if U want while color coats are still wet . I read the article on the paint U used. Try shooting some scrap metal and let it dry , see if it will wet sand . use 1200 with a drop of dish soap and see if it works. then all of us will have yet another product to use ..
