Will this product go bad if it isn't all used within 24 hours after removing the seal?
Can this sealant be used to fill in grout between tiles in the shower? Is it hot waterproof?
Will this adhere a flap down on an (epmd) rubber pond liner? i don’t need it sealed i just want it to stay layer flat.
Can you get this clear?

Quality product

This sealant is excellent. Cure time gives plenty of work time while fast enough to get back on the water quickly. Being in a tube makes easy to dispense and spread. It stands up to weather and vibration great. The adhesion is great and has held strong not had a single drop of water get by. Cleanup is easy if you do it right away. Great value in sealants.

Great product, but Amazon pricing is sketchy with weekly 15 dollar price swings

Any 3M product I've use including this is great. Amazons pricing and availability not so much. Large price swings every few days / weeks and same day, next day, 2 day and next week options come up randomly. I'm sure as always they have an explanation as to why that the lawyers have written. Not to mention the tubes that came in envelopes were dented beyond use and a missing applicator tip on one. But when delivered dent free for 22 bucks its great.

Great product

I have used this product before and it is great. One thing that drives me crazy is when you order these and they are over 18 months past the expiration date, the one I got was well within that, so I was happy. I use the 4200 if I think I may have to remove the item in the future, if I never want it to come lose I use the 5200.

A bit pricey, but the king of marine sealants

This product is very popular among boaters as it has been tested and proven over the years.Before ordering, you should be aware that 3M makes this, the 4200, as a sealant that can eventually be removed if needed. They also make 5200 which is intended to bond permanently, as in prepare to be destructive if you need to undo the bond.So, with that said, think of 4200 as a super high quality marine version of bathroom caulk/adhesive sealant. With that in mind, use it for all leaks and repairs with the knowledge that if you ever have to "undo" anything, you can. And keep the 5200 in mind when you really, really, really want to bond something for life.4200 is obviously more expensive than traditional bathroom caulks, but you are paying for 3M's years of testing and research, as well as years of testing in the field by boaters around the world. This product has a great, well-earned reputation as a no-nonsense sealant. I bought a tube to fix a leak on the flybridge of my boat, and of course once applied, my leak is no more. Just be sure to clean the area well, with acetone, before applying (as you should with any sealant).
