Bummer, sorry to see that for sure. Not sure how successful a dye or paint will be, the gouges will still be visible and the dye or paint won't match exactly. A professional re-spray of the bumper will at least give a uniform color but he gouge will still be present. Some places can fill, sand and paint on the plastic very well but your talking several hundred dollars again. You might want to try a few body shops and see what they say after they look at it. Good luck!
