if ur doing the inside plastic dont primer it, i used autozone duplicolor interior auto spray paint, 3 cans did the rear side panels the back panel, the door panels and i ran out about half way thru the front dash, and had to get another bottle so i bought 2 just cuz i didnt want to go back, all of the rear panels of ur car are easy to remove so u can pull those all out and paint them out of the car, when i started pulling the door panels i decided it was easier to just roll down the windows and paint them carefully, the dash is the hard part, u can remove the whole thing but not easily, i pulled out my center console, and emergency break panel (all of these have easy to find screws that just need backed out), the hard part is painting the front dash up by the window, i eventually covered up my window with newspaper and carefully masking taped the newspaper to the very bottom of the window and went to town after trying to do it without covering it up and ended up overspraying onto my windshield and had to use a razor blade to remove my overspray, good luck let me know if u need more insight
