i used to work at a carwasha nd had this stuff called NEW ALL. lets just say it made ANY rim look new. except for the rust, but yea, if yuo got it in your eye, you were done with the manager said so we all had to stand back when we sprayed it off. took 2 mins per rim to get it off witha pressure washer... it was some strong shiznit

willwren'* spot on with the ceramic pads idea. All three of our Bonnies had the crossed laced and the time spent cleanning off the cheap break dust wasn't worth the lower price. Plus the added breaking power can be priceless.
WallyWorld used to have a neat Scotch Brite coverd wheel brush that was diamond shaped like the spaces, can't find here anymore.
