Plenty of people have done it, but the plastic that the faceplate is made of is designed to take a beating.
Paint is absolutely not. People that have the most success are the ones that spray an automotive urethane through a hobby airbrush.
I just simply got an XCM faceplate. I have the airbrush and everything to do it since I also do model cars, but I just didn't feel like going through the effort.
