Is there any product that I can apply to my wheels that prevents brake dust from "sticking" to them? I have 20" chrome wheels and the brake dust is horrible on them after a couple of days of driving. I've tried to clean them and applied NXT wax but it didn't really seem to help. I read that Michelin has a brake dust repellent that you spray on and it adds a thin layer and helps prevent brake dust from collecting on your wheels. Anyone try it? Or are there special wheel waxes that I can use?
