I've used Rustoleum, Rusloleum 2X, Krylon, MinWax, dope and Duplicolor over Monokote, Econokote and Ultrakote. If the paint isn't compatable with oil or fuel it will get sticky fast. It's perfect for electrics. Rustoleum enamel will flatten out and produces the best finish without any sanding. Any of it will chip at the edges if your not careful.
