The fact of the matter is that all of the damage is "underneath". That is, on the part of the plastic that faces the road. I wouldn't really care so much about it now besides the fact that one side of it hangs down a little and scrapes on speedbumps, steep driveway entrances, etc. So a repair, regardless of the method, would look better than it does now, as you can see it hanging down a little. Maybe I should take a picture.
