Hey. I know a lot of people use Pam on their aluminum wheels to protect them from pitting over the winter months. I haven't tried using Pam yet but I'd like to know if the overspray affects your brakes at all. Do you take the wheels off to spray it on or cover any holes through the face of your wheel to prevent it from getting on the brakes? I usually just keep them well waxed but the Pam method seems a lot easier.
