No that looks way too deep, a PC wouldnt polish that out unfortunately.
My mums car was keyed all along the side and although with a lot of work on the PC it has made some of the less deep parts less visible, the main deep part of the scratch is no better really.
(swear) little bastar ds, if i had spotted them doing that to my car, the only red on their scummy little hands would be the blood from there face, not the paint from my car.
