Plasti-dip would be something to try. If it starts to peel off it removes very easily. My rims are done in plasti-dip and they have held up fairly well. I just realized now I should have put on at least one more coat. I will probably redo them at some point. If you've got questions about the stuff, just ask. A bunch of us have used the stuff on a number of different things. Just myself, I've used it on my rims, grill insert, front and rear emblems, and the chrome ring around the shifter. So far it's held up great and been on for I guess about 3 months now.
There are pics on another forum of a guy with the chrome bumper like you have plasti-dipping it and I think it looks fantastic. Another guy used it on his front and rear chrome bumpers. It's foolproof stuff to use and goes on very easily.
