I can speak of exeperience, but from what i've heard they come out ok and teh damage is almost undetectable but the coating they use apparently doesn't last too long and starts to peel off after a while.
I guess it depends on the place if they do a good job or not. I guess best way is to get 1 wheel done and see if your happy, if not get new wheels.
