I'm in the process of preparing my father-in-laws black Astra ready for sale and there is a scratch about 6" long on the rear quarter. I would normally send for it to be mopped, but it's not too deep and I would like to repair it myself. The scratch isn't deep, if you felt it with your eyes closed you wouldn't think it was there. In my ****nal of valeting products I have the proverbial T-Cut, Turtle Wax Colour Repair with the black chipstick and also some 1500 grit sandpaper. I also have associated finishing products such as polish & wax etc. I can upload a photo in a couple of hours if that helps. Thanks in advance.
