I had some brand new wheels for my GT500 a couple years ago and applied 5-6 coats of cermic coating for wheels. It did make it easy to clean or wipe off. Power washing the wheels made it quick and easy too. Didnt not prevent it from minor rag scratches though. Had it like that for a year and half before selling the car. I've had another set on my truck ceramic coated with just two coats and it wasnt as good as doing the multiple coats. Of course I did this myself and for $50.
