I woud polish the scratches lightly with an automotive scratch remover product for appearances sake, then rub on a couple applications of CorrosionX corrosion preventive treatment, then apply a high quality automotive polish. I would reapply the CorrosionX to the area a couple of times a year, and before each trip to a corrosive environment such as near the ocean, followed by the automotive polish.
The idea is to keep a protective coating over any openings in the clear coat the scrub pad may have produced. Otherwise the panel scratches are likely to develop filiform corrosion when ocean or road salts come in contact with any bare aluminum.
The same is also true of the Airstream's panel edges and holes under the panel rivets. They are also exposed metal and need protection in corrosive environments, so as long as you got the stuff handy, you might as well protect all the exposed metal on the trailer. The Airstream dealer probably did not mention these areas.
