If you'd like to really really REALLY make your life miserable.... then use a polisher on your newer model Airstream.
It will burn and melt the plasticizer-clearcoat on your aluminum turning it into a smeared, burned, blackened mess. Then you will have to chemically STRIP the entire trailer to bare aluminum... and THEN you'll HAVE to polish it regularly for the rest of it's life.
Do NOT attempt to polish a newer, clear-coated Airstream.
