## Questions & Answers

**Q: Can. This be used to attach cermamic tiles in a hot tub witch will be under water?**
A: I used it to seal a sailboat. As I know it cannot be used under water. This being said, it resists exposure to elements, it is kind of elastic after curing, but is not very adhesive, you can easily peel it off.

**Q: Will salt water deteroriate this?**
A: Not sure. Used in fresh water only. Great product.

**Q: Will this work good with polyurethane front splitter?**
A: Depends on what it trying to do. It is not a glue, just a premium silicone sealant, made for wet conditions.

**Q: Does this product work to seal cracks in rain boots?**
A: Temporary fix. New boots makes more sense.

### ⭐⭐⭐⭐⭐ Good marine grade silicone
*by J***F on November 14, 2023*

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.
