## Description

3M Marine Grade Silicone Sealant is designed for the harsh marine environment. This sealant provides a durable and long-lasting seal.

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

## 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.

*by N***E on January 8, 2025*

I love this stuff. I wouldn’t use anything but it. It’s great quality. The smell isn’t strong. It’s not messy. And is great for sealing up lights and stuff to the hull.
