i don't know what kind of paint used for my interior. i have to be honest, it was already painted before i got the car. but anyway, i do know what you need. go to your local hardware store/paint store and pick up some plastic sealer (rustoleum product i think) ask them for it in a spray can.
1. clean surface
2. clean with 3M general purpose cleaner/mineral spirits
3. wash off and repeat step 2, wash off again.
4. apply 1-2 coats of plastic sealer (allowing to dry in between)
5. apply any color paint of your preference
6. let dry between coats, should do like 3-4 coats
7. spray with some clear coat and let dry and cure before use
4.(alternate) Krylon Fusion paint, 3-4 coats, jump to step 7
like JR said, multiple thin coats are better than one thick coat. if its something that you touch alot, make sure you use alot of cleaner to get all the oil from your hands off before painting
1105 - i would get black carpeting, not just floor mats. get a black steering wheel, paint the door handles black, and like you said the seats. break up some of that porno red.
thanks guys for the compliments, always appreciated
