Hey all, I picked up a used ninja 650r for a song from a local dealer near Sacramento. However, somehow (and I really don't understand how) the frame was scratched into the silver paint to the black below, right about where the knees would touch the frame if it were possible they could. In any case, it looks unsightly and I want to paint over it. Would it be something I could do myself with some touch-up paint, or is this a collision/repair shop job? Thanks in advance.
