Insta Finish - Car Care Products - Detailing Clay bar - 110 gms Description Detailing Clay Bar quickly and easily removes oxidation, bugs, road film, brake dust, paint overspray, and other harmful contamination from your car's paint and glass in seconds. Clay pulls out all the things you can not see, but you can defiantly feel, like industrial fallout, rail dust, and brake dust. Though they are not visible, they feel rough or gritty and may cause patches of paint to appear dull, even after waxing. As these contaminants oxidize, they create rust spots within the paint. Once this happens, the oxidation is considerably harder to remove and will most likely take a good bit of paint with it.
