anyone try this?? I was reading the back and it said it could be used for rims...to help prevent brake dust from sticking?

 

no do not use 303 on your rims because they are painted / are clear coated.. use Zaino or reg wax BUT because of the heat generated on the wheels Carnuba wax won't last very long..

so in short, care for your wheels the same you car for the exterior of your car. wash / wax
