If you are going to put this foam in something else, I wonder if that
expanding "Great Stuff" spray foam would be of help. (home depot,
lowes, etc).

If, for instance, you were thinking of putting your sheet in a hold or
something, you could spray this expandable foam instead.
I don't know if it 'likes' to be wet and turns to a sponge - but that
you could easily test for.

No, it doesn't (help/work well). Froth-Pak by Dow, or Fomo Hand-Foam, by
Fomo is closed cell and far cheaper for the volume needed. GS is open cell
and will absorb moisture readily, and be very expensive for any but crack
sealing.

I just went through this for my boat (not for floatation, but for
insulation, but the principle's the same).

From my notes:

froth pak 888-868-1183 option 2 local guy rep sez ok careful about
expansion http://www.dow.com/pusystems/product/fpport.htm will help you
calculate volume needs

fomo.com spray in, $42 for 2cf (where to buy?)

1 330.753.4585, home office

I wound up going with Fomo as it was available in larger (2CF rather than
only 1CF) small sizes, and cheaper, too.
