This stuff makes a seal that will last for years on most materials, but it does not stick well to some plastics. It does stick to others, and metals, and fiberglass & wood. It sets up as hard as a car tire. It's a bit of a mess to work with and it can be hard to clean up. Once the tube is open, & air gets to it, the remaining material will set up inside the tube & it will not be usable anymore. even if you stick a plug in the hole at the end of the tube. That's why I buy it in small tubes. The white version will turn a little yellow if it is left in direct sunlight for a long time.

Works as advertised. The best for marine projects.

If you need a guaranteed watertight seal, this is it. It is messy, difficult to work with, and hard to clean up, But it is worth it in the end. As a marine mechanic there are hundreds of boats along the west coast of Florida that iv'e put this on below the waterline. Most are commercial vessels that live in the water and are used in extreme condition, and as far as I know, they are all still floating. Ive put my faith in this to keep million dollar boats sealed, trust me it works. Note once it is on, it is on, it is VERY hard to get off. If it dries on your skin you are going to wear it for at least 3-5 days, don't ask how I know. Great stuff, worth it!

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.

This stuff is amazing. Used to coat rivets and seal transom bolts etc. it’s never coming off (even off of your hands so wear gloves).

5200 always works, never fails, used it for past 20 years

3M 5200... quality stuff for use on my boat.

Good product. Delivered in-time.

Definitely a very high quality silicone, very strong and weatherproof. Better quality than most off the shelf silicone if you need superior holding power that is weatherproof

Brilliant for repairing kitesurf bladder
