Some Jamoke "brushed" my front bumper, left front, right on the radius where it curves around tight to the fender. It is whitish, probably white surface that caused the blemish. NO paind deposit discerable by touch. I tried one of those cotton type treated things that come in a can for polishing, etc., ain't touching it. What's you'se recommendations, please? What's available thats slightly more aggressive, please? TIA.
