3M 06580 Marine Adhesive/Sealant Fast Cure 4000 UV, White / 1/10 Gallon

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

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.

I bought this product for sealing the lens to a Bomar hatch frame on our sailboat. It worked great and provided good adhesion to both the plastic lens and the metal frame. I then decided to use it when replacing a portlight window. It seems to have worked very well there as well. It seemed to be easier to work with than a competitor's product that I used on a previous portlight. Time will tell as to how well it holds up and remains watertight. I especially liked that the instructions on the tube said that cleanup can be done with isopropyl alcohol. As cheap as isopropyl alcohol is, I was excited to use a cleanup agent that worked well and that I didn't have to feel that I needed to use sparingly due to cost. the alcohol cleaned up the sealant very well. The only negative that I can say is that it is fast cure (as the label says). It was almost too fast cure when applied to the lens. I left it set a bit too long (20-30 minutes) before dressing up the seam and it was difficult to smooth out-- my fault for waiting too long. As long as you clean up the seam and smooth it out relatively soon, it should work great.

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.

una vez que lo abres ya no lo puedes almacenar, sólo utilice un 10% del producto el resto se pego y la parte trasera de la lata se rompio al tratar de reutilizarlo
