3M Marine Adhesive Sealant 5200

I've used this for over 25 years in all sorts of applications. It's durable, reliable and permanent.

Great stuff! I saw other reviews that people did not get the nozzle, but mine had it. The tube is metal and the base of my tube was dented but it didn't prevent me from being able to use it. Be aware it takes 7 days to cure, and stays tacky for a couple of days. If you get any own your project or on your hands rubbing alcohol removes it when it's wet.

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!

This 5200 is the best. I had issues with my 3 seasons room leaking at the outside sill areas. I tried many other silicone sealants. This 5200 did the job. Excellent product. Will buy again. Messy but worth every penny!!!

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. Done P.S. Could have put my project together with just this no need for rivets as I was using Composite Aluminum Panels..

Best product has a sealant on the market. Highly recommend will hold anything tight and waterproof.

Works good and very strong holding up the plastic bond for tight waterproofing seal. It’s a bit sticky at first but once it cures up in 24 hours it’s rock solid with no water leaks.

Good adhesive. 3m. Can't go wrong.

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.

Used to install awning rail on my tent trailer. I was somewhat apprehensive about whether this would hold or not but after driving 4 hours, and on dirt bumpy roads, it has held up amazingly.

Este pegamento es una bestia! Lo Utilice 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.
