Review: You will be glad you chose this over bubble gum when you are out on the water !! - This stuff is great when you need to seal a hole in your boat. It is thick and tacky enough to hold a gasket in place while you mount it, isn't too runny and seals as a non-brittle but strong bond so it wont crack later. Buy this when you need it don't expect it to last long after you open the cap and use it. It is a fair price to pay when sealing areas you need to keep water out below your boats water line ( if you think this is expensive look into the 2 part fusor products used in the transportation industry). If you want to keep extra around I suggest buying a spare tube to keep unopened. A tip for those worried about "blowing the tip off" cut a large enough hole for the product to flow through...its thick and tacky, also use firm even pressure do not try and get it all out at once. If you have to you can place the tube in a bowl of hot water to soften the Adhesive and make it more fluid and easier to squeeze out. I used this for quite a few projects, recently I mounted a rod holder with it to protect the boats paint, and used it when I installed my livewell aerator, I also sealed a hole in the plastic liner of my beer fridge and to patch a gouge in a linoleum floor. I have been able to clean and re-use my last tube many times just by cleaning the threads after each use removing the applicator and punching a nail backwards down the tip. Fair winds and tight lines ! Review: Worked Great! - I read most of the reviews on the 3M Fast Cure 4200 Sealant and was a little warry but after using the product, I am very pleased. Yes, it is not an easy flow product out of the included nozzle but it has to be designed that way or you would have material all over the place. I suggest as others have, do not try to have to small of a hole in the nozzle because it is difficult when using a smaller hole. I kept tightening the nozzle after each hole I filled on my boat and had no problems with it. The product skinned over quickly and cured totally within 24 hours. I suggest everyone, read the directions so they are not trying to use the product for an application it was not designed for. Great product and will use again if the need arises. Wish there was one size smaller because once it is opened, in 24 hours, it can no longer be used. I was filling small screw holes where I removed snap grommets in the floor of my boat and wanted to protect the area the screws had created. Sealed great and permanent till I want to pull it out or put screws back in. ## Features - HIGH-PERFORMANCE SEALING: Form weather-resistant, malleable bonds between dissimilar surfaces and a wide range of marine substrates like wood, fiberglass, and metal - MULTI-PURPOSE MARINE SEALANT: This medium-strength marine sealant bonds portholes, deck fittings, rub rails, screw holes, and stanchion supports while still allowing disassembly - FAST CURING: Formulated for fast cure and rapid results, its tack-free in 1 hour and typically cures in 24 hours - READY FOR WET CONDITIONS: Excels in applications both above and below the water line - FLEXIBLE BONDS: Durable elastomeric adhesion maintains joint movement and withstands stress caused by shock, vibration, swelling and shrinking - For industrial/occupational use only.

The fitting attaching my bimi top is loose from the vibration. Hoping this can help me seal it tight** A: This is a great product, I used it to seal my fitting s on my sailboat. Not too sure it will act as a pure adhesive. If you have fasteners and this product together, this would be a good plan. **Q: Is this available in black?** A: Yes from 3m **Q: Will 4200 stick to pvc, vinyl and abs plastics?** A: as far as i know it will. i have used it to patch holes underwater on marine vessels. **Q: Will this adhere heat cable (snow melting) to a metal roof?** A: Yes but not advisable to use on asphalt shingles in my opinion . ## Customer Reviews ### ⭐⭐⭐⭐⭐ You will be glad you chose this over bubble gum when you are out on the water !! *by D***S on June 5, 2019* This stuff is great when you need to seal a hole in your boat.

Sometimes you will need to remove a fitting. So the 4200 is just easier to use. I use a thin amount on all plumbing fittings. It helps with the seal and boat movement. ## Frequently Bought Together - 3M TALC Marine Adhesive Sealant Fast Cure 4200 (05260) – Semi-Permanent Flexible Adhesive Sealant for Boats and Marine Applications – White – 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 Marine Adhesive Sealant 5200 - Permanent Bonding and Sealing for Boats and Marine Applications - Black - 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.com.ar/products/4737087-3m-marine-adhesive-sealant-4200fc-fast-cure-white-3-oz](https://www.desertcart.com.ar/products/4737087-3m-marine-adhesive-sealant-4200fc-fast-cure-white-3-oz) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-15*
