I have numerous screws on my topside deck of my 2000 Beneteau Oceanis 461 that have started having an occasional drip. No surprise since the boat is 15 years old and spent 8 years in the tropics as a charter boat. I have started removing and re-sealing them and so far, no leaks at all where I've been working and we've had a lot of heavy rain! Just as good as the more expensive 3M stuff!

The small squeeze-type tube is terrible. The cap includes a sharp point for breaking the seal on the tube, but once broken, the seal becomes a flap that keeps obstructing the flow of the sealant. Unscrew the applicator cap, clear, repeat, repeat, repeat. What a mess. The 3M tube doesn't do this.

    Comments about Marine Silicone Sealant:

    I needed to seal around the windows on the outside of the cabin. It was easy to use, a quick fix, but the pre-cut opening on the end of the nozzle was a little big for the job I needed. I had to be very careful not to make a mess.

        I only purchase West Marine adhesives and sealants. The West Marine products have a superior shelf life as compared to the 3M line of like products. All too often the 3M products go hard in the unopened container.

                Can't comment on durability as I just applied it but consistency and application seem on par with higher priced brands.
