CHANGE REPAIR SHOPS "NOW".
Do not ever use any form of silicone sealers on the exterior of any Airstream, "ever built".
The sun breaks it down, and then it falls off, leaving a chemical barrier.
Then, when you try to apply the correct sealer, it will not bond.
Vulkem or Sikoflex, is the only correct way to go for larger seams, and Par-bond is used for small seams.
Ask those who have been there and done that, incorrectly.
