i painted my fox500 1/4 plastics. They were originally red but in mint shape. I degreased with deluted purple poower and scrubbed them down with a tire wash brush (to get in all the crevases), primed with rattlecan, wiped with paint thinner, then painted with duplicolor "trim" paint. turned out nice. Dont know how well it will hold up, but no one will ever be in the back of my car so it really didnt matter to me. I just needed it to look nice and it looks like factory plastics.
