Usually comes to the paint of my car only water and a brushed with a very soft brush Schampoon. My workshop was delivered to me after inspecting a clean car, which I was not thrilled after closer inspection. Therefore, I have chosen this product to remove the hairline scratches brush washer. The result does not correspond to the expected effect, presumably because of this. Crystal Paint Cleaner that would have been better value. The deep cleansing of "legacy" of other paint care products is undisputed outstanding.
