caulking a class c

I also did the sealtite tape. Its defintely a job to do it right but will outlast the life of the rv. Its finally out on amazon and other places just recently.

Also used sikaflex for secondary seal.

Never ever ever use silicone on an rv for any reason it has zero bonding capability. Sika is polyurethane same as whats used in car windshields to bond watertight to the vehicle and will last indefintely
