Sorry MaineSail. I remember that thread but I keep getting mixed up by BoatLife's advertising. It is a good thing you actually spoke to them otherwise I might have taken their product descriptions too literally
Can be applied underwater for emergency repairs. Can be applied to damp surfaces.
CURE: Since Life-Calk sealant is a moisture/temperature cure and requires the absorption of moisture from the surrounding atmosphere, an increase in the relative humidity or submersion in water will result in a shorter tack free time and faster cure.
