That is certainly one effective approach, but the cost of professional repair is likely going to be more than the price of a new unit.
If there is a locally-owned and dedicated paint store nearby, and I do not mean a mere paint department in the corner of some big box on the edge of town, you might be able to find someone who could help you come up with a small amount of color-matched top-coat in an appropriate material that could be spot-applied with an air brush after the surface damage has been repaired, and an auto-body repairman (or possibly someone in a large repair shop for RVs) could help/advise you with all of that.
