If you really want to repair it, take some 600 grit paper and sand out the damage, then take some SEM Weld and fill in the damage and lightly sand again.
Next use some SEM Spray Texture to put the OEM texture look back in.
Depending on how well you matched it, you can sand it down a little with 800 grit.
Then finish it off with some color matched coat...
It won't be as new, but it will look pretty good...
