Just don't use asphalt based ones. Make sure its butyl rubber based.

I used Al's Liner H-N-R. It is a heat and noise reducer. It comes in a one gallon bucket for about $50 on Amazon, a little bit more at Advance auto. I rolled two coats on the floor, firewall and behind the seat and I only used about 20% of the bucket. It can be brushed or sprayed on also.

It does reduce the heat coming up through the floor and firewall. I can't speak about the sound reduction yet as I still have several open ports in the firewall and floor.

Picture of the HNR on the floor. Each coat was about 1/16'' thick.
