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. ## Features - Causes serious eye irritation. - Causes skin irritation. - Suspected of damaging fertility or the unborn child. - Silicone rubber sealant that is mildew resistant, non-sagging and moisture-curing - Remains flexible with excellent resistance to marine environment - Adheres to bare and painted metal, fiberglass, glass, non-oily woods and many plastics and abraded rubbers - Marine, general industrial - Bonding, attaching and assembling ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000R4UB08 | | Best Sellers Rank | 979,306 in DIY & Tools ( See Top 100 in DIY & Tools ) 7,213 in Sealers | | Brand | 3M | | Colour | White | | Compatible Material | Fibreglass, Glass, Metal, Plastic, Wood | | Customer Reviews | 4.6 out of 5 stars 170 Reviews | | Global Trade Identification Number | 00051135080177 | | Included Components | Sealant | | Item Dimensions | 38 x 127 x 224 millimetres | | Item Form | Paste | | Item Highlight | For above the waterline interior/exterior sealing on RVs, boats and more | | Item Type Name | 3M Marine Grade Silicone Sealant (08017) – For Boats and RVs - White – 3 Ounces | | Item Weight | 0.13 Pounds | | Item dimensions L x W x H | 38 x 127 x 224 millimetres | | Item weight | 0.13 Pounds | | Manufacturer | 3M | | Manufacturer Part Number | 00051135080177 | | Material | Silicone | | Model Number | MG Sil | | Number of Items | 1 | | Number of Packs | 1 | | Style | Detailing Product | | Style Name | Detailing Product | | Surface Recommendation | Fiberglass, Glass, Metal, Plastic | | UPC | 051135080177 | | Unit Count | 1.0 count | | Water Resistance Level | Water Resistant | | Water resistance level | Water Resistant | ## Product Details - **Brand:** 3M - **Item dimensions L x W x H:** 38 x 127 x 224 millimetres - **Item weight:** 0.13 Pounds - **Material:** Silicone - **Style:** Detailing Product ## Images ![3M 0817 Marine Grade Silicone Sealant (White, 3-Ounce Tube) - Image 1](https://m.media-amazon.com/images/I/61bBYkyC41L.jpg) ## Questions & Answers **Q: Should I use it to install hoses for the live baitwell?** A: If you mean the hose to pump fittings and live well fittings no **Q: does it set once opened (like 4200)?

Easy to use and easy to clean up. ### ⭐ Not useable. *by K***C on 24 July 2026* Product was so hard we couldn’t use it. Perhaps it pasted its shelf life. --- ## 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.sn/products/74152144-3m-0817-marine-grade-silicone-sealant-white-3-ounce-tube](https://www.desertcart.sn/products/74152144-3m-0817-marine-grade-silicone-sealant-white-3-ounce-tube) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-02*
