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.

Good marine grade silicone

Needed some marine grade silicone for some fittings on my camper and this worked perfectly. Put the cap on after you're done and the product doesn't cure in the tube and become a solid mess like some other products. The only thing which doesn't work well is the threaded screw-on dispenser cap. The thread will strip with too much lateral pressure, which always happens to me. Also, do yourself a favor and purchase one of those metal tube keys that help you squish material out of a metal tube. It will save your fingers from exessive squishing, lol.

Hard to squeeze the product from tube

If it does everything it claims it’s a great product. But….its hard to work with. It starts getting hard after about 5 minutes of opening it. Cut your hole large to help with the squeezing.

As advertised

This product, works completely as advertised. Nothing adheres any better, above or below the Waterline. My only complaint (why I gave value for money only 4 stars) is that they don't make it in any smaller quantities. Often times, you just don't need 3 fl ozs. And once you open the tube, and the air hits the end, you can't put the genie back in the bottle. It's all going to harden, used on the project, or left in the tube :-(
