[ohhenrygsr]

Hey guys and gals just a quick question i'm just trying to seal some leaky rivets to get by this year. I hear a lot of people using the 5200 but i was on 3M website and reading about both the 3M 5200 and 3M 4000 can anyone tell me the difference and witch one i should be using to seal rivets below the water line on a painted hull. here is the info

The 5200 needs 7 days to cure depending on environment. The 4000 cures much faster... maybe 48 hrs?

The 5200 seems to be more fluid. This might help or hurt you depending on the surface angle. If flat, it may seep into the gaps. On the other hand, it may flow away from the gaps depending on the angle.

If you're going to use goop to seal rivets, this is the best goop IMO.
