Comments about 3M 3M 5200 Marine Adhesive Sealant:

It's 5200. Sticks like anything. Seals like nothing else, and makes a hell of a mess if you're not careful.!
I think that you have to be careful where you use it. I think many people use it when they don't need to.

We purchased this product for use around our swimming pool, and while satisfied with the product, the problem was with the packaging. The first tube of 3M-5200 was used without a hitch, but the second tube had a defective bottom which would not slide forward to allow the product to be advanced from the tube. After trying it in 3 caulking guns, we were forced to cut the bottom off the tube, creating a mess, and leaving us with no way to direct the application of the product. In frustration, we ultimately threw away the second tube. [...] I guess I'll try to make my future purchases locally, so there will be a chance to actually speak with someone when there's a problem.

I have used 5200 for over 26 years. I am in the commercial diving industry and specialize in cleaning hulls of vessels, propeller changes and search and recovery. I use 5200 as an bonding agent for the hull cleaning scrubbing pads.
I also use it to repair some of my diving equipment. I have never once been displeased with the performance of this product. Just try it once and you will see for yourself.

3M 5200 is a terrific adhesive and sealant. Used it on wood boat construction and it performed just like I wanted. Very very strong once it has cured.

I used this with a wooden boat restoration. I used it around the keel trunk and also a few other spot below the water line. So far so good.

I used this product to seal around a shower/tub. I originally utilized the water-based silicone you get at homestores. It didn't hold up, and had to be removed & was replaced with this product...which stands up to standing/ponding water. It does seem to set a bit quickly, so don't apply too much before applying the desired surface finish. It's a bit messy (sticky), so keep plenty of paper towels and mineral spirits around to keep finish tool edges clean, etc. It also requires about a week to cure before use. Once done, it's a solid performer. I will not be utilizing the latex product again.

Great stuff, durable, flexible, salt water resistant, incredible strength all round great bonding agent.
Lot of people state that this is messy but I have to say so is any other caulk or glue so I call that bs.
It does tend to color a bit yellow over a couple of years but then again if it's cosmetic you should use 4000 UV.

Have tried all types of adhesive on mining-diving gear. This is the best for diving gloves on bedrock. Takes about 10 days to cure. Fast cure takes one half the time.

I'm building floats for a experimantal airplane and the 5200 sealant works very well to seal all the seams before you put the rivets in. It is very messy.

I used this product to seal the seam of my shower. I've tried other sealants/cocking specifically made for showers and they didn't work well at all, this product has worked very well. So far, two weeks after cocking, it has held up nicely and still looks good. It took longer than expected to fully dry, and was messy to apply, but well worth it!

Comments about 3M 3M 5200 Marine Adhesive Sealant:

Messy, Yes. It works as advertised. Strong & flexible. Use, set tiles in a wood frame, that is exposed to the elements all day long. So far so good. I can't wait to find other uses for this great product.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

Outstanding bonding and lamination product. Many uses in boatbuilding and repair. I've found that wood laminated with 5200 will fail (the wood fibers will pull apart) before the 5200 bond breaks. Waterproof when applied properly Use for permanent installations that you will never wish to take apart. For repairs that might need disassembly someday use 3M 4200 or Sikaflex.

Clean up with acetone when fresh. Product that squeezes out of a joint can be trimmed away with a razor knife a day or two after application.

We bought this to repair a cracked plastic pond liner. It did not repair the leak which was quite large. I would, however, buy products from this store again!

Comments about 3M 3M 5200 Marine Adhesive Sealant:

I don't have a boat but, I have a 25 year old
motorhome. Caulking the seams and windows with 5200 has solved all of my leaking problems. It may be overkill but I think it is worth the longer curing times and tendency to be messy. I use the dish soap on a finger method to smooth/ spread it.This stuff is great!

Comments about 3M 3M 5200 Marine Adhesive Sealant:

Brings a new meaning to the word "stick". Takes a long time to completely cure (7 days), but is set after a day. Be very careful, it can get everywhere. Comes out like a caulk, and then becomes more fluid, so if you put it on thick, it will drip. But, once this stuff has set, it works awesome! I used it on leaky toerail, great seal, no leaks, and extremely strong.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

The easiest way to make this product "non-messy" is to have a bottle of dishwashing liquid on hand. After you have the 5200 in place, dip your finger or other tool generously, in the liquid and smooth it out. There will be some residue, but after the 5200 cures, you can wash the soap off. I built a 27" sail boat and the only caulk/sealent I used was 5200. It will last longer than the boat itself.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

I have never had a product that will fasten two pieces of wood together with a flexable seal like this. You can literly take the screws out after it sets.(don't because I said so) It is not intended to be removable, most wood will splinter before it will come apart. Doens't sand well, so spread it the way you want it.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

I use this instead of the traditional RV seam sealers, but not as a self leveling lapping sealer.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

Expect 2-3 days to become tack free (at 60F). I use it on my boat deck covers and it is absolutly perfect for this application. It would work equally as well in bathroom applications.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

I spent 24 years in an Alalska Salmon Cannery. Never seen 5200 before, but over the years got to rely on this product "everywhere". The only place I found it to "fail" was in higher heat and in multiple "flexing situations"--I tried to glue a continuous rubber-like conveyor belt together. The continuous running of the belt generated too much heat.
One time I was trying to reclaim a good fir 6x6 and trying to remove an 8" long block from the 6x6. I kept hitting it with a 6# sledge, but it would only "bounce". Finding no spikes holding it, I wondered, took out my razor knife and sliced the perimeter. I then lifted the block off with my hand. It was held only by a 1/4" bead of 5200 in terrible conditions for over ten years. Yet, with just the "slice" of that bead it popped off. Like I told everybody there, "if I went into space, two things I would not go without were 5200 and duct tape!! I wish I could find it fresh and affordable here. You wouldn't believe the uses-even glued HDPE (teflon) to wood.

We have a vintage Hottub. There is an octagonal plexiglass "window" for the motor compartment contained 40watt bulb. The window allows subduded light to flood the tub. Your product sealed the plex in place and under 400 gals of H2O at 104 degrees is holding perfectly. Thanks

Comments about 3M 3M 5200 Marine Adhesive Sealant:

The problem of 5200 being "messy" becomes a non-problem if you work carefully and follow the suggestions on the package. Use lots of fresh paper towels (once it has adhesive on it throw it out) and invest in a can of the appropriate 3M solvent. It works like a charm. Yes, it is still a good idea to work carefully. Do not over use and plan on using the solvent to clean up the waste later. Use the solvent to clean up small mistakes and to keep your finishing tools clean.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

Applied with a 1/4" bead then spread with a putty knife, this stuff didn't turn out to be nearly as messy as other reviews led me to believe. Maybe it's worse on fiberglass or a protected wood, but I applied to raw pine and it worked like a charm.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

I have used this to secure metal flashing around a rounded deck surface at my home. The deck is very exposed to high wind and wind driven rain and this stuff has held going on 7 years without any sign of failure. It is messy to use but well worth this relatively minor issue.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

Contrary to the views of many, 5200 does not last "forever". When my 1954 Hinckley went through a thorough rebuild in 1981, we were told by the "experts" that it would outlive the boat.
By 2000 the product was breaking down in almost every place it had been applied. It is a great product but does not last "forever". In many cases, bedding compound is a better choice.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

5200 is the industry standard for structural bonding. pretty awesome strength and has good durability. Have to be careful with it though -- It is not something to fool around with.

Comments about 3M 3M 5200 Marine Adhesive Sealant:

I have used 5200 for a number of applications over the years. It is one of the best products that has ever been created. Just remember: once you put it on something, it's never coming off.
