Better adhesion than silicone and can be removed without damage to gel-coats

Polyurethane and silicone formulated for use on fiberglass. It gives measurably better adhesion than silicone and yet, unlike most polyurethanes, can be removed without damage to gel coats. Fast-curing, low-odor, high-adhesion, non-corrosive and non-sagging.

Simply the best all weather caulk....

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.

Best Sealer in the Market

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!

Great stuff

Been Using Life Seal for years on portlights, hatches etc. It's easy, looks beautiful, and outlasts & outseals the others

A must have for any boat owner

I used it to seal from out water from any screw holes and to seal around accesories I mounted.

Boat Life Sealant

This is the best caulk hands down. It stays were you put it with no shrikage or cracking.

Did not cure and made a holy mess

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!
