I am replacing the roof vents on my 5th wheel. Is this what I need to place over the metal flange and roof interface?

Yes, this is what I have used and then use a self-leveling sealer over the top of the screws and edges of the vent.

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
