Find holes in the body filler and deep scratches in the primer with the 3M control powder. Our control powder uncovers even the smallest surface defects when dry sanding the primer. No surfaces need to be covered and no drying time is required after application. When sanding polyester filler, you can use our control powder to check whether the filler is smooth and free of ripples and whether the lines and contours of the bodywork are straight and flawless. This ensures that the entire undercoated surface is actually sanded before the top coat is applied. For wet and dry sanding. The control powder is solvent-free.
