Hello. I have a 2000 Volkswagen GTI, and the rear bumper has some paint that is chipping off, an some scratches on it. I was wondering if there was any tips or advice on painting the plastic, as I heard it was tricky. I am not sure if I am gonna repaint the whole bumper, because I heard you can feather out the paint to blend it. I am not going for show quality results, just better than letting it keep chipping. The car has been repainted once since it was new if that matters.
