What I did with mine was buff the crappy gold coat off, it's chrome under it and looks better, I did the same to the ramp, trying to paint it would do the same thing peel, I'm going to re chrome my coin toss at some point as its not perfect, but looks allot better than it did with the crapy gold, it is a playing over chrome, if you rechrome it would look better than trying to get a gold look as its a brass plating it will dull down again
