That sucks man. That has happened to me twice now. Some prick got my door/door frame/fender really good and then someone got the bumper cover and quarterpanel on the other side. At least the bumper didnt crack. Mine did :/ I did a cheap fix with fiberglass kit and paint. It looks like ****, but Ill take some pics tomorrow. I don't think youd have too much trouble covering that up. I would try sanding just the smudged areas and touching it up like that instead of sanding the whole corner down and painting, it would be really hard to blend that large of an area.
