I put down Al's HNR (heat and noise reducer) under Al's liner. I haven't had the chance to see if it made a difference. Unfortunately, I've lowered my expectations. There was a thread on a FB page about this subject and someone who did HNR showed temp readings before & after, and it made little or no difference. He ended up applying heat shield materials under the floor in places close to the exhaust. So I'm not sure I'd do it again. Lizard skin is expensive, and you'll need 2 different applications. They've updated their web page and it now seems to be ok under bed liner if you follow their directions. Back when I did this, their web site didn't approve bedliner on top of LS. Bed liner by itself won't do much for heat, but will help some with sound.
