Under the cap is lots of old insulation the "thermo probe" wire, the rivets and screws that secure all outside stuff in that area plus the wireing to the front speakers. Airstream letters and clearance lights. I had a lot of leaks in this area from the windows and the letters.
As I said, its better to cure the leaks from the outside " since thats where the water" comes from LOL.
A good fan out the door "down wind" will take care of the fumes and over spray, only time will take care of the chemical release. A week or so opened up.
