It offers a durable, non-yellowing, flexible seal that adheres to a wide range of materials including metal, fiberglass, glass, wood, and plastics.

## Description

3M Marine Grade Silicone Sealant is designed for the harsh marine environment. Formulated as high-temperature resistant, 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.

## 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.

### ⭐⭐⭐⭐⭐ great sealant, holds up on the water

### ⭐⭐⭐⭐⭐ Great product!

Great product!

### ⭐⭐⭐⭐⭐ 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.
