Paint with Dupli-Color High Performance Wheel Coating.
It will work on plastics, and possibly rubbery surfaces. You can try it if you feel comfortable with trying it on a rubbery surface, but it might chip if the panel bends easily, that's why a hard surface is better.
I painted my dash, gauge overlay, console, air vents, door controls, speaker panels, horn button, dome light surround.
