The steel wiper arms are standard on all of the Airstream Classic and Argosy motorhomes and yes they do rust.
You have several options, you can clean and paint them or replace them. The wiper arms and blades can be purchased from AM Equipment.
The blades themselves are Anco HD 52-20. I can't seem to find the part numbers for the ones I ordered so hopefully someone else will chime in with the correct part numbers.
Hope this helps!
Brad

Interesting how many different wiper blade numbers we are coming up with here. When I replaced my wiper blades a couple years ago I remember having a hard time finding something that would work. I bought NAPA 60-2070 Severe Duty blades and they seem to work fine.
