Great Sealant
I love this stuff. I wouldnโt use anything but it. Itโs great quality. The smell isnโt strong. Itโs not messy. And is great for sealing up lights and stuff to the hull.

Good product but the tube busted
Perfect to touch up our travel trailer seals, but as in other reviews, the tube busted at the bottom so could not finish the job or get my moneys worth of product. Hope 3M fixes the packaging.

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.

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 :-(
