Yes I second...we used this stuff all the time in the shop. But the real issue is probably corrosion on the inside lip of the wheel...even aluminum wheels. I used to see it all the time on all kinds of cars and truck when I was a pimple-popping tire & batter shop tech monkey. If the customer wanted it, we woud take the tire off, or just bust the bead back enough so that we could sand the inside of the rim lip, then blast it with air. Sometimes put a bit of bead sealer over it just to make sure they didn't choke up the shop againThanks!
