I am building a 16 foot wooden boat and use this 5200 marine adhesive to join and seal boards/planks in addition to using screws. It flows well in a caulking gun. It cures well overnight. Its hold is excellent. will buy again if needed.

I have not tested it yet, but it really goes on nicely. Much better than any other product I've used. There arewarnings about proper usage and air quality but it has no scent, however you need around 3 large bottles of fingernail polish to clean up any drops, etc. But it has been good going so far and I would definitely buy it again. I bought 5 cans of this adhesive for one 2" tiled floor 60" x 29". I have been impressed thusfar. Georgette

I used this to seal a leak in an area that other sealants had not worked on and this stuff worked absolute wonders for keeping water out.The only thing i found challenging was the size of the bottle for my application needs but I was able to easily get around that for my unique application but its a standard size of caulking and works with any general contractor style caulking gun.Highly recommend this product!

Used to seal a crack in fiberglass, worked out well for me and cheaper than 3M.

Started to notice water in the bilge, used this to make small repairs / seal leaking points on the exterior of my boat. Such as around rivets / screws, motor mount holes, accessory holes, seams, anything always under water. The boat is now dry as a bone, has held up beautifully for 6 months at least. This is the more permanent type of sealant, not the removable type. Really good stuff.
