Hey we needed someone to try it out and I guess it had to be me, it was a question of time before someone came up with the idea.
I'm not even half way there and if I had to do it over again I would definitely buy polyurethane by the gallon, closed cell / 2 or 3lb
from a big name company like this one
http://www.uscomposites.com/foam.htmlThese pouches I'm using are polyurethane but it's hard to figure out what type/density etc...
When I'm done I'll see how many pouches I used so I can put a price on it. I'm pretty sure buying polyurethane by the gallon is a better deal, but we'll see.
