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. ## Frequently Bought Together - 3M Marine Grade Silicone Sealant, 08019, For Boats and RVs, Above the Waterline Interior/Exterior Sealing, Clear, 3 fl oz Tube - 3M Marine Adhesive Sealant 5200 - Permanent Bonding and Sealing for Boats and Marine Applications - Black - 3 Ounces - 3M Marine Adhesive Sealant 4000 UV (05280), Medium Strength Flexible Waterproof Adhesive Sealant for Boats and RVs, UV Resistant, Cures in 24 Hours, White, 3 fl oz Tube --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4737086-3m-marine-grade-silicone-sealant-clear-3-oz-tube](https://www.desertcart.us/products/4737086-3m-marine-grade-silicone-sealant-clear-3-oz-tube) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-13*
