I've seen people use the stuff on firewalls and the undersides of hoods and stuff. It's that silvery heat reflective stuff that has adhesive on the back and you just stick it on. Any idea where to get this stuff? Since I don't have any heatshields on my exhaust, I've noticed it getting VERY warm down around the console/floor area in my car. If I stick my hand down where the e-brake handle comes out, it's HOT under there. I'd like to apply some of this stuff to the underside of the body where the exhuast pipe passes underneath. If you know where to get it let me know. TIA
