Thanks for the input so far guys.

I'm thinking of trying a couple of products from "dB Engineering" (http://www.800nonoise.com).

For the hood pad, their basic acoustic foam, with mylar surface treatment. Its rated continously up to 107*C and intermittently up to 135*C (whatever that means). The mylar should reflect the radiative heat back into my engine and keep it nice and toasty.

For the trunk, they have a nice foam with a vinyl covering, should be tough enough. Black vinyl should do the trick (hide the grease that its guaranteed to collect).

I think Larry is on to something with the front floorboard and firewall. I'll probly try a composite barrier called "Ultima WM2X".

This stuff is all pretty cheap compared to Dynamat, so its within my humble college budget. Any timely warnings or advice would be appreciated. I'll post my results once the stuff is installed (over a period of months).
