I was hoping somebody with better experience would answer this, but if
you saw input from somebody that it worked OK for them, that'd be good
enough for me. I'm sure there's a wide range of properties of urethane
foam, some of which is completely unusable. When I built N56ML, I
bought standard building urethane foam from a company that made it in
Nashville. They had a 4' x 8' x 2' deep mold that they sprayed (while
mixing) the two parts to make a "loaf"....complete with a big head on it
as it grew, then ran it through a big vertical band saw to slice it to
thickness. They'd make it what ever thickness you ordered. I bought
all my foam from these guys and made one trip to Nashville in a borrowed
pickup truck to get it all. It was very cheap, and best I could tell,
was identical to what AS&S and Wicks was selling. I've seen and used a
large variety of colors, usually yellow, tan, brown, or pink, but
sometimes green as well. You might try building insulation
establishments nearby. Nowadays there are inexpensive DIY spray kits
that may make sense in some places on the plane, but flat panels are
probably best from a weight standpoint.
Even styrofoam from Home Depot works, if you get the right kind. It's
just a lot harder (and therefore slower) to sand, and one thing that
drives me crazy about it is that sanding it generates a static charge,
and you wear half of it around for the rest of the day, as well as
spreading it all over the place. Best strategy would buy a minimal
sample and give it a try, if that's an option....
