We damaged the rear of our caravan, which was repaired under the insurance policy, and at the same time our local dealer (Dickinsons) in Bradford filled and sprayed half a dozen dents caused by the awning poles. They did say that one of their staff 'specialised' in repairing such dents. You can't tell where the work was done, at all, and even though we thought we knew where they were there's no visible difference in finish, shine, or colour.
If it really bothers you then ask your local dealership how much it will cost.
