Looking for foam...
Great Stuff is OK but doesn't go far.
Anyone know of a low-cost high-volume foam?
A friend mentioned "2-part styrofoam" and said it was used in packing
boxes (shipping ups, etc).
Want to fill canoe and a 21' boat for floatation. Hardness would be
nice too - but mainly water-proof fill is desired.
Thanks,
Elliot
