Sealed-cell aircraft padding. It's available in 1/4" and 1" thicknesses.
(You can double-layer 1/4" to make 1/2", etc..) Great material. Far more
effective than the lead-like thin stuff. I used it in my hand-built car and
it's awesome.

Anyone can install the Type IV. No big deal. And Raby has an airconditioning
setup, too. Just ask him.
