## Description

Size:3 oz | Color:Clear | Number of Items:1 3M Marine Grade Silicone Sealant is a high quality silicone designed for the harsh marine environment. It forms a mildew-resistant, non-yellowing seal that remains flexible even after years of exposure

Review: 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.
Review: 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.

## 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 14 November 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.

### ⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ As advertised
*by W***I on 6 January 2024*

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 :-(
