I'm strictly interested in foam for chassis stiffening...

I mentioned in my reply that the TDS for that product (pdf on main
page) mentions that it "cures to a semi-rigid closed cell foam"...  My
question was whether or not there's a product out there that cures to
a "rigid" closed cell foam.  My guess is that such a product would
stiffen a chassis more effectively, if it exists...

Thanks,

Mark.
