As I was a union painter for 17 years let me asure you the key to any good paint job is prep (usually about 70%)and a good primer. Ive painted glass, ceramic tiles, plastic and just about every surface. You can sand or use chemicals to etch a surfce for adhesion. Make sure you have a clean surface and apply multiple thin coats. The difference between thin coats and thick is if you hit one with a hammer it will dent the other will crack and chip. Just some professional advice.
