There has been a lot of research done on the Airstream Forum regarding the different effective sealants to use for specific applications on the Airstream Travel Trailer.  Each one of the alternative choices above has their merits.  I present them here for consideration.  However as always, use at your own risk.  I make no claims for success, other than the fact I use specific ones from the above list myself.
