Not so much a "coating" as it is a shell, or even a container of sorts, around the watermelon. It's like a half-inch thick or more, so, for me at least, it's not as impressive as first implied by the title.

They actually used this during the iraq war to coat buildings in certain locations. Bet it's still being used for all sorts of military uses. Look forward when they can make it clear.

Rhino Lining is much better. Line-X is the cheaper, lesser competitor.

Not sure which brand, but Mythbusters used spray-on bedliner to make a "house" bomb proof.

I want the next plane I fly on to be made outta this stuff.

I wouldn't wanna artificial vagina made out of that stuff, 'tho -- I mean, not at the moment, anyway.
