3M Marine Adhesive Sealant 4000UV, PN06580, White, 295 mL Cartridge

Works better than any standard RV sealant. I always use marine quality items on my RV... They last longer and perform better on the road.

The 3M Marine Adhesive Sealant 4000 UV delivers excellent performance for sealing and bonding in tough outdoor conditions. Its UV resistance ensures it won’t degrade or discolor, even with prolonged sun exposure. The adhesive is flexible after curing, making it ideal for marine use and projects where durability is key. It’s easy to apply and provides a strong, lasting hold. A dependable choice for anyone needing a sealant that can withstand water, weather, and time.

I used this product on my RV. Works great. Don’t buy what the camper stores sell. Boat products way better than camper products. Still holding up great after several trips.

Works well. But you have to use the whole tube other wise it gets hard.

This is the best sealer I have ever used, the self-leveling is a great tool that allows the flow into the cracks, also sets up quickly, I did apply this stuff while it was above70 degrees which I believe helped with the cure time It may cost a little more but trust me it is well worth it for sealing the roof on my car trailer.

Product is great, easy to apply. 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.

This product, like all 3M products is outstanding. I used it to reseal a Pilothouse to deck seam that had developed some leaks. The previous seal/caulk had dried out, shrunk, and cracked. I cut it out and refilled the joint with 4000. I cleaned the area with acetone, masked off beyond the seam and applied 4000 with a caulking gun. The sealant flowed smoothly and filled the joint completely, easily resealing the leaky joint. This product is waterproof so cleanup is messy if you get it where you don’t want it. It does not smooth with a wet, gloved finger, merely smears. Apply enough to fill your joint and no more. Small overages will be “cleaned” up when you remove the masking. I applied the 4000 to a joint almost forty feet in length overall and the cure time is not so quick that I couldn’t easily pull the tape without pulling the caulk. It made an attractive seam and fixed the leak. Unlike 5200, 4000 doesn’t dry/cure so hard that it has to be ground out to remove it, but can be cut out with a knife at some future point if necessary. Unfortunately, this item was shipped by Amazon and though the box was undamaged, the interior bag was never sealed properly and the included nozzle was absent, having escaped through the improperly sealed inner bag before it was ever placed in the box. The fulfillment center never checked that the item was complete, because it was not. The delivery was quick and secure, the filling of the box was not.

This is THE product to use for marine applications when you don't want a permanent bond. The issue for me is, it's quite expensive and I only tend to use a fairly small amount at a time for repairs (e.g., installing a replacement stanchion). They tell you that you need to use it within one week of opening. This is only true if you want to dispense it through the nozzle. What I do for small jobs is punch a small hole in the side (I use a nail set or a nail), squeeze a little out using a caulking gun, and spread it with my finger (in a nitrile glove), then slap some tape over the hole. I've now been using one tube of a year on 6 small jobs, and I expect to do more.

Pero para apuros está el Fasf

es un sellador especializado para uso náutico de muy buena calidad recomendable para embarcaciones de recreo como veleros y yates

Lo aplique en un kayak después de 3 meses sin problemas

Buen producto, tengo poco de haberlo aplicado a mi kayak y va bien. Al secar su textura es suave, parecido a silicón. Éste modelo 4000 es semi permanente, por que se supone es relativamente sencillo retirarlo para cambiar la pieza o tornillo que está sellando y volver a aplicar una nueva capa del sellador. ACTUALIZACIÓN (FEBRERO 2023): No recomiendo comprarlo. El producto es bueno pero solo pude usarlo 1 sola ocasión y el 99% restante del producto no pude usarlo. Cuabdo lo abrí limpié la boca y lo cerré con su tapadera. Al intentar usarlo de nuevo la tapadera estaba rota, supongo que se hizo presión al secar el producto de la punta. No hubo forma de retirar el producto seco dentro de la boquilla...intenté con desarmador, con un tornillo, con acetona para suavizarlo y nada dio resultado. Los objetos traspasan el sellador, pero al apretar para que salga producto se bloquea con el que está seco y no sale nada incluso usando mucha presión...un completo fiasco ¡Tengo el tubo lleno de producto pero es inutilizable! ¡Dinero tirado a la basura!

One of the best rv repair and modification sealants.
