Marine Adhesive Sealant 5200, Black, 10 fl oz Cartridge with Nozzle | Permanent Bonding and Sealing for Boats and RVs Above and Below the Waterline Waterproof Repair

Great product. Works well at keeping water out but don’t get on your clothes. It will be there forever.

3M 5200 is absolutely the best $$ can buy. Perfect above and below the water line - every sailer needs to keep a extra aboard

Purchased this product to attempt to seal a challenging flashing issue which has three different material in an awkward transition.I removed all the material from the previous two attempts to waterproof the area, leaving a larger than previous opening to work this material into.After cleaning and prepping the surfaces, I began to applying this 3M product. It is thick, but not problematic to dispense - possibly other reviewers were dispensing through a smaller orifice than me - I used the full tube opening without a tip. The product is exceptionally easy to manipulate and smooth out - almost putty like. Unlike other products like silicone and polyurethane, it didn't stick much to my applicator and thus stayed were I wanted it (without sag) and also smoothed out easily.Bottom line is it adhered to all three materials, filled the voids perfectly, looks great, and the leak is no more!I highly, highly recommend this product - it's amazing!

Works great, but there are no instructions in the box.Basically, you hold down the on/off button for 2 flashes to get it to turn off in 1 minute, hold it down for 4 flashes it goes off in 15 minutes. You're welcome!

i worked in the boating industry for 35 yrs. doing everything bow to stern top to bottom inside and out. the black is ok but takes quite a while to cure. if you really want an fast indestructable adhesive sealant use the 3m white fast cure. this stuff actually cures faster when exposed to moisture just as it says on the package. many many times i have used this on thru hull fittings, bonding wood, fiberglas, steel, stainless, aluminum and many other materials and it even cures underwater. it will cure in about 12 hrs. once cured it bonds to practically anything. i even use it to repair soles on my shoes if they come apart. then they are better than new. i have used this stuff wherever you need a serious rubber seal, bonding materia, even seals water pipes,fittings etc. i wish they had made it in black fast cure. not sure why unless there is a difference in the chemical makeup. it can be painted using enamel, polyurethane, laquer. not sure about latex, maybe acrylic. one thing is its almost impossible to cut or remove it.

Good product

TAKES 7 DAYS TO CURENeeded to reseal my 12v 100ah lifepo4 battery. My battery design is pretty dumb and they put the handle on the top lid which was only sealed with the bare minimum of a few dabs of some type of similar adhesive on the side that came undone. The only downside to ordering it online was that the nozzle was cracked at the bottom and broken off of the retainer ring but the nozzle was still usable.Ive used the 3m 5200 adhesive sealant before so I already knew what to expect. If you can use caulk gun you can use this..but make sure you dont get it on you or its really hard to get off. Gas will work but it sucks lol.i do wish I had gotten the3m 5200FC that cures in 24 hours instead though.

Works great, appears to keep the leaks out of my jon boat repaired rivets.

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😊

Incredible product for boats or anything that requires permanent repair or attachment. have used it on my boat and exposed to sun and weather for years, no deterioration.

Delivered on time, well packaged. Used on the boat transom to fill in transducer screw holes. It's easy to use. It does take a week to fully cure but works perfectly. I recommend for anyone working on a boat. Use a caulk tube plug to seal and save unused product.

Este pegamento es una bestia! LoUtilice para unas botas y quedó incluso mejor que con la suela original, lo unico es que es dificil resellar

Great product. |Awesome adhesion and sealing qualities.
