I've used generic asphalt padding
and it does work pretty well to deaden sound transmission. Comes in
several thicknesses, too. Make sure every large, unstressed panel has a
good bit on it. It reduces transmission of sound by lowering the
resonance frequencies of the panels: sound that is absorbed by the sheet
metal from the engine and road isn't re-emitted into the cabin...
For heat, tho, jute padding (sometimes with a foil backing) really does
the trick. Just don't get it wet! It's kinda like a sponge...
I've never used POR15. But I've had good luck with Hammerite, both in
bomb cans and in quarts (thin it out with xylene 20% or so, and shoot it
like auto paint.) It's been durable, goes on easy enough, and you can
get that cool 'hammered' finish... BTW, you can buy gallons of xylene,
toluene, and acetone at the local hardware store! I went looking for
DDT after seeing that!
Toto, I don't think we're in California anymore...
