The very best - tough and resiliane
I've used 5200 for years - produces a great, very strong, resilient rubber compound that will last for years and really does the job. I bought this small package because it is nice to have a small amount around to use for small jobs without having to open a full canister. Highly recommended.

Very effective sealant for boats, a must-have for marine applications
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.

2004 Winnebago Sightseer hood detached from hinge. Used this. Seemed to still be working when we traded it in.

Marine sealant - fast curing
Good value for your money and very easy to use. This product worked very well for a sealant on RV and dries very quickly.

Best adhesive to use in wet areas.
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.
