noticed a dirty black mark across the side of my Clio on the quarter panel, it looked like one of the grips on my brothers bike had hit it. anyway after over doing it trying to get it away iv taken away a bit of the shine from the paint and it doesn't have the smoothness the rest of the panel has. is there a product that can bring the shine back at all? i tried using some t-cut product that brings back the natural colour but that hasn't worked too well. any suggestions would be appreciated.
