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.
