3MMarine Adhesive Sealant 5200 (06501) Permanent Bonding and Sealing for Boats and RVs Above and Below the Waterline Waterproof Repair, Tan, 10 fl oz Cartridge

Great product! Works great! Highly recommend!

3M Marine 5200 is very much a marine industry standard -- for a reason. It does what it does very well, but don't order this unless you know exactly what that is. It's a "sealant" that takes a full 48 hours to cure... and once it does cure, congratulations, whatever you used it on better be something you want to stay put forever-ish.It's also a "use it or lose it" $20 tube. Open it -- and consider anything you leave in the tube as toast. You're not just going to stick a nail in the tip like it's RTV and use it later. It's also fussy about how you prep the mating surfaces. Acetone? Perfect. Alcohol? Congrats, it will never set. Never. READ THE LABEL.

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.

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!!!

Works great Takes forever to dry (defiantly not 3! more like 4-days -1 Star*)!! I got mine with the tip!! No holes, came just fine!! Stuff is great!! Strong with a little flex to it. Think caulk with strength..For the reviewer talking about the tip not working? ?Poke a hole in the end of the tube! You do have to cut the end off on the nipple you screwed on!! Also there is a pop top lip on the bottom, you have to pull that off as well. Looks like you figured that out ok? But Yes you do have to cut the tip off and ----> poke a hole in the end of the tube as well!! Before screwing the nipple on!!So here is a recap... Poke a hole in the end where the tip screws on and cut the tip off the nozzle a little at an angle and pull the pop top pull lid off the bottom. DoneP.S. Could have put my project together with just this no need for rivets as I was using Composite Aluminum Panels..

I use this product daily as a marine mechanic Just apply and clean up with acetone

good stuff

Most importantly this stuff will not cure even after 2 weeks! I don't know why it's is so finicky but apparently the consensus is it most likely will jot cure for you either.I purchased this because some users online said it was the best permanent bond for rubber/neoprene muck style boots and waders. However, like other purchasers, this stuff generally will NOT cure. I googled it and read that just like many urethane adhesives it needs moisture for curing. I am now trying to add water to it and and set a damp paper towel over it to aid moisture curing and my first attemp a few hours later the water seems to have liquified it more. I did have a small portion cure but the majority of it has not. I tried squeezing out a glob like you do with epoxies and then stirred water into it and applied it to some rubber. The left over mixed with water spot has not cured after a few hours. Don't get it on anything you don't want it on because it's quite greasy like and is difficult to remove. It gets into small crevices and threads but does seem to be out with lots of scrubbing but generally leaves a stain.I am wondering if windshield adhesive would just be a better product for bonding and sealing.
