Hi I would like to know if it's possible to spray Auto-Air/Wicked paints on top of Enamel/Rustoleum paints or vice versa, and what clear coats would be suitable for the finish. I will be restoring old bikes, Rustoleum (Combicolor) are the best (and reasonably cheap and accessible) for covering bare metal without primers cus they stop rust and harden really well, very long lasting glossy paints. But i'm not sure if i want to deal with the hassle of changing rustoleum paint all the time when working on fine graphics cus they are really hard to clean, so i want to use Auto-Air in combination with Wicked colors for general graphics and finer detail. The company that sells Combicolr Rustoleum has a very good clear coat (1K and 2K hardness) to use with the Rustoleum, but i'm wondering if it might interfere with the wicked and AA paints. Any ideas?
