3M Marine Sealants for Campers
Having come from the boating world, is there a reason folks don't use the 4200/5200 marine sealants from 3M? They last years and are proven sealants. They can be tough to remove but isn't that the poi...

Definitely the 5200 I haven’t had a leak since I started using it. Check out West Marine. They have it on sale from time to time. I got the last batch for 11.99 for the 10oz caulk tubes. (And no I don’t work for them)
