great sealant, holds up on the water
Used this for sealing some fittings on my boat and it worked exactly as expected, no leaks at all and it's held up through sun and water exposure without cracking or pulling away. The cap seals well so the tube doesn't cure between uses which is a huge deal with silicone products since they can dry out fast. Only minor thing is the dispenser cap threads can be a little finicky if you push sideways on them but that's pretty minor overall. Solid marine silicone from a brand you can trust and I'd buy it again.

Works great.
Needed to seal up around a vhf antenna. Easy to use and easy to clean up.

Not useable.
Product was so hard we couldn’t use it. Perhaps it pasted its shelf life.

Defective squeeze tube
Entire bottom of the tube blew out. Lost half the tube, went all over. 3M needs to fix the squeeze tube. Lots of reviews showing this being an issue. Stuff ain’t cheap.

Ehhh. Tube hard to squeeze
Realizing that this is a superior Product to most standard caulk products for a shower and bath, we found this very difficult to squeeze out of the tube. We ended up throwing away the nozzle accessory because forcing the caulk up that narrow Path used all of my strength. We’ll see how it holds up in our shower tub combo
