I painted the ones on my '08 R3T a few years ago when I did a front tire change. I masked off everything (and I mean everything) so no over spray would get on the bike or my garage floor. I used black rattle can engine paint to shoot them. Turned out nice (I thought). That was about 40,000 miles ago and they have held up okay, though I should have touched them up but haven't. Even with a couple of chips in them they are still a big improvement over the way they looked before. Go for it.
