Marquis's thrust duct.

Marquis Songer's thrust duct. I think this is the second one, after he broke it at DuQuoin.

This is a special 2-part spray foam that is really strong when it's done, and as nearly as I know it's actually waterproof. As opposed to any other spray or pour foam I've encountered.
