I have used this sealant before, on hatches, port lights, screw holes , bathrooms and just about anything you need to seal anywhere. It is easy to use, can be smoothed out, with a wet finger, stays white and has a little shine when it dries. I have never had it peel off or yellow. It held up very well in my bathroom as well as everywhere I used it on the boat. Just be mindful there is a difference between the lifeseal and the life caulk. This one dries pretty fast, the other does not.

I bought a 10oz cartridge of black LifeSeal to seal a Lexan lens to a metal hatch frame. It never cured a bit, leaving a gooey mess to clean up. Left black streaks all over the deck after it rained 3 days after applying (I was still hoping for a cure at that point).[...] Don't gamble with this!

          I used this product to stop a persistent water leak along my boat's toerail. It went on smoothly, dried fast and stopped the leak.

          Comments about Life Seal Sealant:

          The first time I used it, I was somewhat taken aback by how quickly it came out and how difficult it was to work with. Gee, just like 4200. Choice of caulk is a matter of personal preference.... personally I like the water clean-up aspect, but it's sure not as easy to work with as home latex caulk. Protects a zillion times better, however,

          Better than silicone or polysulfide. Better than all the 3-M products. I've used it on the boat and at home, and it is great!

              This caulk is a must for every boater. It adheres to wood, fiberglass, and metal and will not crack. Its elasticity is its best quality.
