For several years, I've been using wheel brushes that I got from Advanced Auto parts stores called a Wooley Wheel Brush. The things are a plastic handle with a tapered wool covering that did a great job of not scratching the black paint on my Corvette's Grand Sport wheels. All the new wheel brushes I've seen have been nylon bristle things that scare the "H" out of me for using on my expensive wheels. My last brush is about shot and I can't find any more. I found a post on a Porche board that says he uses a "Wheel Woolie" from Pep boys. No Pep Boys in Nebraska, so I called several in surrounding states and not one of the guys I talked to had any clue or seemed to care enough to even check the shelves. Anybody got any ideas? Even a Pep Boys part number would be great. I've been known to take long road trips just to get a $5 item I can't get in Omaha.
