You wouldn't happen to know what the best method is for sealing the plate to the trailer skin is? On the airstream restoration show on "Classic Rides" on the D.I.Y. network they used silicone caulk, but the original sealant seemed to be some sort of plumber's putty.
The DIY Network is gonna rot in hell for telling folks to use silicone. NEVER USE SILICONE ON AN AIRSTREAM!!!
The substance you found is called 'butyl tape'. Any RV store should carry it. They also sell 'putty tape' but I would not use this as it hardens eventually. A roll of the butyl tape costs a few bucks and will last you a very long time!
Just run a line of the tape around the inside of the flange, screw or rivet it in place, cut the squeeze-out with a plastic knife and remove the excess and you're good to go!
