My wife scraped her New Infinity QX56 into the Garage and got white paint on the front bumper. Instead of informing me, she took it to a detail shop and the detailer wet sanded the bumper with what appears to have been 600-800 grit sand paper. The clear coat took a beating. The good news is the detailer got rid of the white paint on the bumper, the bad news is he the clear coat looks really dull where he sanded the bumper. Is there anything that I can do to git rid of the dull finish from the sand paper?
