If you remove the patina (sand or wire brush until they look shiny) from both surfaces and there is sufficient bonding area it should.Make certain the joint is secured until the adhesive is fully cured. **Q: Will this work on a 2 inch pvc pipe coupling that is under water** A: If the coupling is underwater and can't be moved out of the water, or the water drained, then this would be the best chance for a repair of anything I know. I would clean and steel wool the surface before putting this on. I'm just guessing at what the situation is and if this would be a solution. But I'm really impressed with 3m 05220. It was made to stick stuff like speed sensors on the fiberglass hulls of boats while they are still in the water. **Q: does this work on polyethylene (Kayaks)** A: Yes Once setup you can't remove **Q: Can the adhesive be sanded** A: Once fully cured it can be sanded. It will fill the sand paper a bit. As with any adhesive, the quality of the surface prep will determine how well the product sticks to the surfaces and thus how finely you can feather the product. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by N***N on April 16, 2024* ### ⭐⭐⭐⭐⭐ Review *by J***M on January 13, 2024* ### ⭐⭐⭐⭐⭐ Review *by A***R on March 19, 2026* ## Frequently Bought Together - 3M Marine Adhesive Sealant Fast Cure 5200 (06520) Permanent Bonding and Sealing for Boats and RVs Above and Below the Waterline Waterproof Repair, White, 10 fl oz Cartridge - 3M Marine Adhesive Sealant 5200, Mahogany, PN06502, Flexible Bonds, Long Work-Time, 1/10 Gallon Cartridge, 10 fl oz --- ## 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/2635804-3m-marine-adhesive-sealant-5200fc-fast-cure-white-flexible-bonds](https://www.desertcart.us/products/2635804-3m-marine-adhesive-sealant-5200fc-fast-cure-white-flexible-bonds) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-11*
