I´d like to repaint my interior dash and any plastic parts inside the car. I want to do the dark grey in a dark red, the lighter grey in a lighter red and the black in white, and maybe the vents blue...just thought of that....a little patriotic, yeah, well, anyway my question is for those who have already done this mod, what kind of paint did you use? winters are brutally cold and summers can be insanely hot. So I need something to withstand that and I want it to last, can I get some regular paint from my local hardware store? or would I need to spend a shit load on some custom automobile paint?? It´s possible to do this when my car is having the engine rebuilt and it´s just sittin there, being a lawn ornament. Thanks in advance.
