Au contraire, joburnet. :nono I'm a happy user of Meguiar's APC+ (mixed 4:1 water:APC) for a couple of years now on all sorts of wheels, as well as my rubber bumpers. Only problem I've had was this summer, when I tried A2Z on Eastwood Hi-Temp-painted Karmann Ghia wheels, and A2Z stripped-off that paint better (worse?) than any paint-remover I've tried.
So I don't think you need to apologize for APC. Use it in good health. :up
