Review: Absolutely amazing product - Purchased this product to attempt to seal a challenging flashing issue which has three different material in an awkward transition. I removed all the material from the previous two attempts to waterproof the area, leaving a larger than previous opening to work this material into. After cleaning and prepping the surfaces, I began to applying this 3M product. It is thick, but not problematic to dispense - possibly other reviewers were dispensing through a smaller orifice than me - I used the full tube opening without a tip. The product is exceptionally easy to manipulate and smooth out - almost putty like. Unlike other products like silicone and polyurethane, it didn't stick much to my applicator and thus stayed were I wanted it (without sag) and also smoothed out easily. Bottom line is it adhered to all three materials, filled the voids perfectly, looks great, and the leak is no more! I highly, highly recommend this product - it's amazing! Review: TAKES 7 DAYS TO CURE - TAKES 7 DAYS TO CURE Needed to reseal my 12v 100ah lifepo4 battery. My battery design is pretty dumb and they put the handle on the top lid which was only sealed with the bare minimum of a few dabs of some type of similar adhesive on the side that came undone. The only downside to ordering it online was that the nozzle was cracked at the bottom and broken off of the retainer ring but the nozzle was still usable. Ive used the 3m 5200 adhesive sealant before so I already knew what to expect. If you can use caulk gun you can use this..but make sure you dont get it on you or its really hard to get off. Gas will work but it sucks lol. i do wish I had gotten the 3m 5200FC that cures in 24 hours instead though. ## Features - POWERFUL MARINE SEALANT: A permanent solution for bonding marine substrates like wood, fiberglass, and metal - VERSATILE APPLICATIONS: Tough yet flexible polyurethane polymer is ideal for deck housings, hull fittings, porthole mounting, fiberglass transoms, and underside molding - WARD OFF WATER: Resists saltwater and weathering both above and below the water line - FLEXIBLE BONDS: Its elastomeric bond absorbs the stress of vibration, swelling, shrinking, and shock - LONG WORKING TIME: Allows plenty of working time, achieving handling strength in 48 hours ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000Y89JC8 | | Best Sellers Rank | #4,204 in Automotive ( See Top 100 in Automotive ) #32 in Thread Lock Sealers | | Brand | 3M | | Brand Name | 3M | | Color | Black | | Compatible Material | Wood | | Customer Reviews | 4.5 out of 5 stars 10,605 Reviews | | Global Trade Identification Number | 00051135052051 | | Included Components | marine sealant | | Item Dimensions | 1.4 x 4.9 x 8.8 inches | | Item Form | Ounces | | Item Highlight | Permanent Bonding and Sealing for Boats and Marine Applications | | Item Type Name | marine sealant | | Item Weight | 4.8 ounces | | Item dimensions L x W x H | 1.4 x 4.9 x 8.8 inches | | Manufacturer | 3M | | Material | Plastic | | Material Type | Plastic | | Model | 5200 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 051135052051 | | Style | 5200 | | Style Name | 5200 | | Surface Recommendation | Floor, Wall | | UPC | 051135052051 | | Unit Count | 3 Fluid Ounces | | Warranty Description | AS Printed | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** 3M - **Item Weight:** 4.8 ounces - **Item dimensions L x W x H:** 1.4 x 4.9 x 8.8 inches - **Material:** Plastic - **Style:** 5200 ## Images ![Marine Adhesive Sealant 5200, Black, 3 oz Tube - Image 1](https://m.media-amazon.com/images/I/6154aDqHkIL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Does the 10oz. Silicone require purchasing a special caulk gun? I was previously shipped tubes made of metal with pull tap opening like on a soup can** A: I was concerned as well but it has an internal plastic follower cup that a traditional caulking gun presses against: Similar to the traditional caulk tube. The additional metal seal helps to prolong the storage of the adhesive sealant. **Q: Has anyone tried mixing a color pigment into the glue before application? Will this effect the cure?** A: I have not and can only advise you give 3M support line a call and ask them and if you can I am sure they will tell you which coloring to use. I would not just mix in any color you don't know how the glue will react to it. Give 3M a call I am sure they will be glad to help. **Q: My kitty put a couple of pin hole sized punctures in my scuba bcd, causing a small, slow leak. will this patch it?** A: Yes it will. Allow five days to cure. Don’t use the fast cure. **Q: Is it paintable?** A: Yes it is paintable ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolutely amazing product *by C***S on April 4, 2026* Purchased this product to attempt to seal a challenging flashing issue which has three different material in an awkward transition.

I used it on a curved balcony wall and it was stronger than a post and rail assembly. There is a learning curve as it will be stiff in cold weather and a tad soft above 75°. Very strong bond. ## Frequently Bought Together - 3M Marine Adhesive Sealant 5200 - Permanent Bonding and Sealing for Boats and Marine Applications - Black - 3 Ounces - 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 TALC Marine Adhesive Sealant Fast Cure 4200 (05260) – Semi-Permanent Flexible Adhesive Sealant for Boats and Marine Applications – White – 3 Ounces --- ## 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.hr/products/4613298-marine-adhesive-sealant-5200-black-3-oz-tube](https://www.desertcart.hr/products/4613298-marine-adhesive-sealant-5200-black-3-oz-tube) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-15*
