Could this product be applied under water? I.E. Swimming Pools?

Jamie Hyneman of Mythbusters use to use it in the Caribbean to repair boat leaks outside the boat in the water. This was according to Adam Savage in a You Tube build video. https://youtu.be/YZV4A4Kl0yM?t=1521

Is this made in China?

Technical details upon this listing state "Country of Origin - USA"

Will this product work on small concrete/masonry wall cracks?

I guess to waterproof as it is very maluable
