Anyone have any tips for painting theses? I have tried everything, I don't know what kind of plastic they are made of but it is tough stuff. Nothing bonds to it or attacks it, I've tried MEK, Acetone, toluene, even the purple primer for PVC pipe nothing even softens it.

I first tried plastic lacquer spray then enamel, it all just flakes off after a little time and with the seat belts rubbing it. It would sure be nice if they came in white instead of black only.
