I tried searching this thread for deep scratches, but couldnt really find anything without some serious reading.... so I'll just ask real quick, when I was installing my front springs, I nicked the pain on the fender with the CC plate. It's straight through the paint, what should I do to make sure it doesnt start to flake, rust, etc?
straight through the paint? As in primer/metal is exposed? All you can do is touch up paint or repaint.
No amount of polishing will fix a defect once its down to the paint/metal level.
