Fixing cost depends.
If you just have them fill it, sand it, polish it.. or a repaint.
Touchup - Proably a hunded.
A repaint will be several hundred.
You can try it yourself for under ~50.
Get touch-up paint from the dealer.
Fix the error.
Wet sand with 1000, 1500, 2000, 2500
Meguiars unigrit or 3M trizac or Micromesh.
