i followed a painting guide and painted the side metal and top metal panels, but now i would like to paint my front panel which is plastic (u know one of those played out chieftecs). im wondering what kind of paint and what steps i should take. Im planning on just a very light sand, hardly any at all, or do i even need to. i dont want to use vynl dye as it costs more. but should i clear coat also? also i painted 3 of the usual metal fan grills black, but i am wondering if i should also clear coat over?. thanx in advance.
