3M Marine Adhesive Sealant 5200 - Permanent Bonding and Sealing for Boats and Marine Applications - Black - 3 Ounces

Hold well. Form any under water application. It’s a little messy to work with.

Folks there is a other version that allows for curing in 24 hours, this takes 4-7 days to cure and is quite pliable after initial set. I used on a cracked all-in-one shower pan. I was skeptical for the first 24-48 hours because of the slow cure. Be patient, when it cures it is stronger than steel and has some flex to it - perfect for standing in the shower and not worrying. It created a water tight that will probably last longer than the house itself. Again, if you need something to cure faster, seek out the similar name 3M. This is the real deal!!!

I used this to seal the roof and rear hatch area of my van. This sealant is world class

The sealant worked great on my travel trailer and cleanup was pretty easy. I used it to seal the trim seams, and I was very happy with the results. Only complaint is the nozzle was missing and I had to find one, for the price that was a pain.

Im telling you know whatever this stuff touches with be water proof and never come apart! Your jon boat rivets will literally never come out again or leak this is more permanent than JB Weld lol its awesome

Best adhesive I know of for sealing and bonding at same time. Cures hard and resilient. It is my go-to if I want it waterproof and securely bonded. If you might have to remove it later without cutting, use 3M 4000. I always get this size, small size tube is way overpriced. It is gooey and gets on every thing so wear gloves and keep mineral spirits solvent handy to remove any smears.

Excellent quality and holding power in this sealant. I used to affix a transducer mounting board to my 2003 tracker targa b9at and have had zero trouble with it. Highly satisfied.

Unfortunately, I had to rate this with something.. and there are no negative numbers. I was dumfounded that this product demonstrated 100% failure to do anything it is advertised to do..even for the simplest of use. It failed as an adhesive... and where it would NOT bond it failed to seal. I swim 2.5 - 3 miles everyday and am in the water for anywhere from 80 to 110 minutes non-stop. I customize the swimming goggles I use because I can't find goggles that won't put ring marks on my boney eye sockets and over that kind of time they begin to really hurt. I glue custom cut pieces of an old wet suit to the soft material around the goggle lenses. I read many reviews of this product and bought it because I thought I had found a winner and I'd finally found something that would last... but that was not the case. Within one week the bond failed completely. Now maybe the glue isn't made to withstand chlorine, I don't know.. it wasn't indicated and if it is a marine sealant who's to say someone wouldn't be using it around a pool? It only makes sense it could be. And I might be wrong but it seems the silicone pads on the goggles and rubber wetsuit material would bond (that is to say "melt" together) but what I got was a nice clean surface on both the pieces when they came apart. I put the glue on both surfaces and waited over an hour for it to get sticky (otherwise it was like water), so maybe it doesn't bond to itself. Seems every glue I've ever used recommends doing this. I weighted the bond down overnight and because of the "dry" time, did not get them wet for over a week. I can't imagine using this useless stuff on a boat, or any type of motor, or condition where vibration would be constant. And the kind of set up time required the boat would likely sink if I'm trying to seal water out. I'm glad other people got some satisfaction from it, I sure didn't for that piddly little use...and I'd be willing to bet down the road they will all be doing it again. It took well over a week for the glue to become non-sticky. All in all.. I would not recommend anyone buying this stuff for anything unless you just like the smell of it. Sorry 3m but... best go back to the drawing board.. or put some information together about how, where, what.. maybe "your" definition of marine...directions for application and something on the literature other than the fear based stuff about getting it in the eyes or swallowing it. I normally would not say anything and just throw the stuff away but it was such utter failure...maybe I can save someone the trouble and time I went through.

The 3M White Marine 5200 sealant is great as it solves the issue of mine. Zedi Online was excellent in customer service response, as Mr. Aman is so responsive to my emails and messages as he was so great to help me with the fast delivery. He really puts 100% effort into resolving the issue and helping customers like me. From delivering on time, to giving great communication. A big Thanks to Aman as well as Zedi Online😊

We'll see how long it lasts so far so good.

Great product. |Awesome adhesion and sealing qualities.

I use this to seal the leak that was coming from the roof rails of the 2007 Honda Odyssey. The original seals have already dried up. Be prepared to have messy hands when using the stuff. This particular sealant will take a few days to cure. People say that they will cure faster when it makes contact with water. There is also a fast cure version that hardens in 24 hours. That one I used for a paddle boat.

Tarda en curar pero cuando lo hace queda bien aderido
