I always use marine quality items on my RV... They last longer and perform better on the road. Review: If this can't seal it, it can't be sealed - Moving to a new house, we unknowingly let a vinyl lined hot tub (Softub) sit in the summer air upside down for three months. BIG mistake. This resulted in several rips and tears (including one 2 feet by 6 inches!) in the inverted sagging of the long-water-dependant vinyl. We thought our hot tub was a goner. Tried numerous hot tub rip repair kits, and none of them worked well enough for this major repair job. The hot tub was aging and had served us well for nearly a decade, so we didn't want to purchase a complete replacement liner because of the price - either fix it or toss it. Vinyl patches provided were strong enough, but none of the vinyl patch kit adhesives were able to really withstand the stresses of a full 300 gallon water load on the stretchable vinyl. We made all repairs while tub was empty so as to obtain the best seal. In addition to vinyl-specific glues and patch kit adhesives, we tried vinyl contact cement, shower pan liner adhesive, and every single type of PVC/vinyl glue at the local home improvement store. Not even Loctite plastic bonder would hold once the hot tub was full and chlorine was added to the water. As a last resort, we decided to give this "below the waterline" "hull repair" "permanently flexible" sealant a try - and WOW! it sticks to everything. We gave it a good cure of several days (this was outdoors in winter, so took a bit longer). We used this to adhere the vinyl patches to the tub' vinyl liner, to each other, and to feather around the edges so as to prevent bathers from tearing up the sides or water working the sides loose from the jets. 2 months in to this repair, from which no other product/system/glue previously lasted longer than a week. Much impressed by the miracles of modern petroleum strength commercial chemical derivatives - nicely done 3M! ## Features - MULTI-PURPOSE MARINE SEALANT: This medium-strength marine sealant bonds portholes, deck fittings, rub rails, screw holes, and stanchion supports while still allowing disassembly - EXCELLENT UV RESISTANCE: A distinct ability to withstand the sun's rays allows it to excel in challenging outdoor industrial, transportation, and construction environments - COLOR STABLE: Maintains its color in applications above and below the water line - FLEXIBLE BONDS: Durable elastomeric adhesion maintains joint movement and withstands stress caused by shock, vibration, swelling and shrinking - PAINTABLE WHEN WET: Forms a skin in 30-60 minutes but can be painted over with water-based paints immediately after application - For industrial/occupational use only.

I would choose at least a medium strength silicone sealer. **Q: Will this work to seal the top on a raised roof van?** A: 3M Marine 4000 UV Adhesive is an excellent UV resistant caulk. The 4000 is especially designed for fiberglas and teak. If you want the toughest structural waterproof joint use the 3M 5200. Do not use the 5200 if you plan to take the raised part off. Once cured the 5200 forms a tenacious glued together joint. **Q: does this caulk contain polyurethan?** A: No, unless it goes by another name. I did not see it listed on the label. -Jim ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best RV Sealant Ever... *by T***R on February 1, 2026* Works better than any standard RV sealant.

Ensure you clean/ dry surfaces well prior to application and tape off where you don't want over spread. 3M Marine Adhesive Sealant 4000 UV comes in thin metal cartridges like tooth paste not a paper tube. If not shipped in proper packaging, the cartridges will be dented, bent or even punctured. I received two wrapped in plastic bag envelopes both packaged in a paper Amazon bag together. ZERO protection. They're not punctured but are bent up. I had to straighten the bottom where the pull tab is to work in my caulk gun. ## Frequently Bought Together - 3M Marine Adhesive Sealant 4000 UV, PN06580, White, Medium Strength Flexible Waterproof Adhesive Sealant for Boats and RVs, UV Resistant, Cures in 24 Hours, 295 mL Cartridge, 10 Fl Oz (Pack of 1) - 3M Marine Adhesive Sealant Fast Cure 5200 (06535) Permanent Bonding and Sealing for Boats and RVs Above and Below the Waterline Waterproof Repair, White, 1 fl oz Tube - 3M Marine Adhesive Sealant Fast Cure 4200 (06560) – Semi-Permanent Flexible Adhesive Sealant for Boats and RVs, White, Flexible Bonds, Underwater-Safe, 295 mL Cartridge --- ## 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.tn/products/9786698-marine-adhesive-sealant-4000-uv-pn06580-white-medium-strength-flexible](https://www.desertcart.tn/products/9786698-marine-adhesive-sealant-4000-uv-pn06580-white-medium-strength-flexible) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
