I meant you but thanks for the info from other detailers. Have you ever used a boar's hair brush? I have for the past 7 years and NEVER had any scratches because of it. It allows the dirt and crap to "flow" up into the bristles until you pass it through the rinse bucket. It doesn't hold the dirt next to the car's surface like some mitts, sponges, or cloths will. Another advantage is the bristles get down into cracks and crevices and around trim alot better than any of the other methods. I'm not trying to be a boar's hair brush nazi, but unless you tried one, you won't know how well they actually work. My most humble $.02
