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...

I'm sure you know that 5200 is a very strong adhesive making later removal difficult if that is a consideration. 4200 is weaker but still much better than anything in the RV store.I certainly agree. I never used them in a marine application but have used both on my TT. I never knew of 4000UV, however the other two stay whiter than any other RV specific sealant.
