As I mentioned before....most aluminum fabricators...(screen rooms, car ports) sell the rolled "tape" 3" wide, that is used to seal the seams between 5' wide insulated aluminum roof panels. I've used it throughout my truck...it's easy to use small pieces to do the inside of the doors. Also used it overhead on the roof...no sagging. It has a white vinyl skin, sells for $13.00 a roll and it takes 2-1/2 rolls to do all the cab and door surfaces. The 12" stuff I got from our Home Depot was a pain to apply and smelled like tar.
BTW...it also works...no twang when you close the doors. Hope this helps.
