I applied Mother's SynWax (liquid) to my wheels back in the beginning of May. I knew I wouldn't have access to a hose, and honestly didn't feel like buying ONR, so I wanted to make sure the brake dust didn't bond to the wheels. Sure enough, I finally got to wash the car a couple weeks ago, and the brake dust that was sitting on the wheels all summer came right off. I must say I'm quite impressed, especially considering it took maybe 10 minutes to seal my wheels (they're very simple 6-spoke OEM wheels). I have to admit, I didn't notice much of a difference at all in the appearance of the wheels though.
