Best in market.
5200 is one of the best marine adhesive in the market and it’s fast cure makes it even better.

Marine seal
It works really good I used a lot of 5200 3m and this one works just as the same very strong after it cures only thing I wish it had was a cap for it so when you don’t use all of it it doesn’t dry out

Long cure time
Strong bonding and sealing. Takes FIVE days to cure however.

Great product for boaters.
The 5200 is great for many things for boaters. It is a bit expensive but goes a long way if you seal it good every time you use it with a roofing nail in the tip .
User
