I painted my glossy (matching bodycolor and clearcoated it). My car is a daily driver, so it's exposed to a lot of scratching risk. Well, all I can really say is just be careful when you reach for buttons and stuff so you don't scratch the paint with your fingernails or whatever. I don't wear a watch or ring (not yet anyway

) so I have no worries there.
Oh yeah, I also waxed my painted pieces so they're easier to wipe down when they get dusty or finger-printy (I just invented a word). Somewhat of a related topic.
