This Detail Factory Wheel Face Brush sports quality flagged-tip bristles, meaning the tips of the bristles have been mechanically distressed to make them softer and safer. This both prevents scratching and creates more lather during use. The chemical-resistant bristles are also flared to cover more area and get the job done faster. This brush is also part of the ProGrip line, featuring a comfortable and ergonomic handle design with rubber overmolding.
