What brand/product are you using or planning to use? There's a lot to choose from it seems.

Not a slabside but an undercar exhaust car. I applied Lizardskin, a ceramic coating, on the underside of my floor panels, rear wheel well/trunk panesl and transmission tunnel. I have had some bubbling directly above my mufflers where it seems to have lost adhesion in areas. That could be due to my not scuffing up the aluminum enough for a good bite into it or just a limitation on the material. Otherwise, it probably helps but it's not enough and something is needed on top of the floor panels on the inside to. Not sure if I would use it again.
I applied a mastic dampening material (B-Quiet) and then a temperature material over that (Thermo-Tec) on the top side on the floor pans. I would not use the B-Quiet again probably due to it's weight. Instead I would use Frost King duct insulation like ERA applies to the foot boxes and I think it has a better insulation rating. It probably weights half as much. the Thermo Tec was a foil-surfaced, woven silica insulation and a self-adhesive backing. Very good stuff, not real expensive and light weight.
Lots of good products out there. Some are primarily for dampening road noise and vibration more than for insulation value.
