High gloss clear coat on crusader 295rst scratched

[Clif]

Took my rig to dealer to have awning motor replaced as part of service they washed my rv but they used some kind of super abrasive brush and it appears to have damaged the clear coat which I noticed when I covered it for winter am planning on using meguiars marine gold on it to attempt to Restore finish, rv had some oxidation but I was planning on using meguiar line of marine products to restore and protect against UV damage. Has anyone had issues like this? Dealer was Robert Crist. In Mesa AZ outstanding service department not so much wash department.
