    • Best adhesive to use in wet areas.
Size: 3 fl oz Style: 5200FC Pattern Name: Adhesive Sealant
There is nothing else that comes close. My records show I have purchased it 3 times from Amazon. Slow curing so you have plenty of time to position the part and then use something to hold it in place for 24 hours. Generally considered permanant - you will have to cut the glue seam to remove the part so don't use it on something that might need to be removed years down the road. Strong - you bet. I glued some flat pieces of metal to tubing on my boat. I can stand on these parts with all my weight. Pay attention to the directions - no alcohol cleaning prior to gluing. Can be frozen for longer life span. And NEVER wear good clothes while using this. Nothing will take it out of your clothes if you make a mistake. Use painters tape around the glue area to keep the 5200 off the surrounding area. Keep lots of paper towels near by - it is messy and seems to go everywhere by itself. Uses moisture to cure so can get wet before cured. And finally - guessing here - may be hazzardous to use in a fish tank. Lots of odd chemicals in this stuff. ... show more

    • Works Well For Roof Fix

Needed an adhesive/sealant to repair roof seam tape. Edges of tape lifted during hurricane Ian. Used this product to glue down seams using a small hard rubber roller. Worked well because cure time is quick. A bit messy to work with in this application but very well worth it. The prospect of replacing the roof tape would have taken days and cost hundreds of dollars. This method only cost me one tube of sealant and about 3 hours. ... show more

    • Worked to strengthen engine mounts
Size: 10 fl.oz cartridge Style: 5200FC Pattern Name: Adhesive Sealant
I used this to strengthen my engine mounts as they were getting old and the engine visibly tilted. The mechanic said it was "normal" but the engine tilted a good 3-4inches when in gear and engine revved, so instead of painfully replacing the mounts I filled them with this sealant. Was an absolute pain in the ass to squeeze out this sealant, its very thick, but I managed to fill the two primary torque mounts fully. I had the car in my garage with a humidifier running and all of sealant cured within a week (about 1.5in from surface to innermost area). The sealant has remained in the mount for a couple months now and survived the heat of the summer and engine bay. It does seem to have slightly separated from the rubber itself, but that was expected due to the nature of the rubber. The sealant itself remains like a filler block and works like a charm, engine barely tilts half an inch now. I know this was an unorthodox application for this product but it works as I needed it to. ... show more

    • Very effective sealant for boats, a must-have for marine applications
Size: 3 fl oz Style: 5200FC Pattern Name: Adhesive Sealant
I've used this 3M Fast Cure 5200 for all sorts of purposes over the years, primarily on my boat. Whenever I drill a hole or put a screw into the boat's hull or transom, this stuff is going on the screw threads or in the hole to seal it from water permanently. I've patched holes up to 1/2 inch in diameter using just 3M 5200 and I've never had a drop of water get in through that hole afterward. It's pretty amazing stuff. I've also used this stuff to adhere loose trim to fiberglass inside my boat, it works well and bonds stronger than most glues on the market. The only downside to 3M Fast Cure 5200 is that it's messy and not very reusable. Even the small tubes are expensive. When you cap after using, make sure you find a way to use the rest of this sealant in the not-too-distant future as the cap will become difficult to remove, and the sealant will harden up near the cap. 3M 5200 sticks to just about every type of material on the planet and is impenetrable to water. For boats, 3M 5200 is a must-have, use it to quickly patch up holes and cracks, it'll keep your boat afloat without any leaks whatsoever. ... show more

    • It works!
Size: 1 fl oz Style: 5200FC Pattern Name: Adhesive Sealant
There’s a reason 3m charges so much for not stuff. IT WORKS! I used this to coat some rivets in my Jon boat while I replaced them. No leaks and this stuff seals great! I would recommend wearing gloves and having a rag on standby when using it. It can easily get everywhere.
