White 3M Marine 5200 Adhesive / Sealant 10 fluid ounce cartridge

I love this stuff but you need to understand its properties and when to use it and when not to. 1. It only skins over in about 24 hours and takes up to 7 days to cure a 1/4" bead so it can only be used when the item is not going to be disturbed before it cures. This does help it from hardening up in the tube and I can usually keep a tube around all summer on the boat for small sealing jobs. (There is a Fast Cure 5200) 2. it is very strong once cured. They claim it is for permanent applications. It can be cut to remove an item but the residue is almost impossible to remove. 3. It is very messy and not as viscous as other sealants so caution must be exercised to get a good application. Don't let it drip where you don't want it. Set the caulking gun on cardboard when you stop dispensing and relieve the pressure.

Have an above ground pool? Or any pool with a liner? BUY THIS!!!!!!! NOW!!!!!!My brother had a Large tear in his pool bottom. It spidered in every direction. I put a BLOB of this on a disposable trowel, and took a dive. I spread it like a 3 yr old frosting a cake. (The pool was already 9yrs old, this was it's Last Stand.)4 YEARS!! later, NOT - A - DROP!!!This stuff Cures Under Water!! There is Nothing like it!! We used it on our boats, as it was made for, but the POOL?? ! ! It saved us Thou$and$!!Warning - It does harden once opened, so don't plan on getting more than 2 uses from the tube. Used it once without the nozzle. 2nd time, I speared the hardened end and got use. By the third time? I had to pierce the side of the tube and scoop out what I could. But even if you only get One use, It's Worth it.

What can I say...this is the best stuff for marine use, really, anybody who works on boats would agree. What makes this purchase special is the price....here at Amazon it's just-about half price of your family hardware, or boating supply store. Here's a little secret too...keep the partially used tube in your freezer for future use, otherwise it WILL harden-up on you.

After purchasing my first pop riveted Jon Boat over the winter I learned a lot about how to buy a boat. Since I couldn't just take the anchor back, I had to fix the leaks. I thought about welding the aluminum. I thought about putting new metal down. Etc etc. I finally talked with a friend that recommended this. After using an angle grinder to clean up the cracks that were visible I laid this down in a few steps.... to help with drying time. Next I moved on to every rivet on the bottom of the boat. Problem solved. Perfect for solving water leaks.

I love this tan sealant for covering rubber covered cables to the lights in a fountain, the color blends with the floor. My only complaint, which is true of all tube caulks, is that after partial use the remaining caulk hardens. This isn't caused by air infiltrating at the tip but at the plunger end and there is no preventative. I do have to replace the caulk every 4 years because it eventually hardens and cracks but I don't believe there is a better marine caulk that can withstand constant sunlight and water.

If you need to PERMANENTLY seal something onto your boat, this is what you need! Do not use it for anything that you want to remove in the future.

I don't know what this is made of but it is strong. It takes a long time to cure but once it does, IT DOES. It forms like rubber but like highly dense and super flexible. It's worth every penny if you don't want water getting into your boat or whatever you're sealing with it.

We had to top up our inground 15,000 gallon swimmingpool several times a week, up to a certain grout line. As it turned out, there were a couple of places where the grout had disintegrated and allowed water to leak out. Anyhow, I was researching this and found some solution that were EXPENSIVE! One was well over $100. Anyhow, a friend pointed me towards this and IT WORKED! Thank God for friends! ;-)

Good

takes a long time to set

Price great

Great stuff, used it for years. Got this to mend some expensive BMW motorcycle boots, worked perfect. You have to give it time- a week at least- but fully cured, it’s bulletproof.

I used it to re-glue the trim in a 1968 Johnson outboard cover after I painted with epoxy. From experience, I know it will stick to anything,hold up for years.

Worked good but not cheap

great

I don’t know when this product would ever be applicable. I tried on two different occasions to use 3M marine adhesive sealant “fast cure” 5200.

Very good product for sealing difficult areas. Much more agressive sealant/caulk than most box store products

It does what it says it’ll do. It seals perfectly well. I used it to make my motorcycle wheels tubeless, and it could have been better.
