I plan on doing the door panels and other areas (kick panels, B & C pillars) with the Dynamat knockoff product. One thing to note, Dynamat (and the knockoffs of similar construction - butyle rubber & foil) was developed to reduce noise specifically from panel vibration (aka drumming). While it does help some with insulation, it is really a sound deadening product as opposed to an acutual insulation product, and used primarily to quiet an interior.

The floor was recoated to match the asphalt based coating that came from the factory. I may do layer of the HR700 product if needed to help with the heat. I really think most of the heat is going to come from the sun beating down on the roof, so that is why I wanted something thicker up there. The Dynamat knockoff of the doors should help reduce road noise and act as a moisture barrier under the original door panels. Obviously the HR700 is too thick for the doors and other areas to use under the upholstery panels. Plus it needs to stay away from the moisture present in the doors because of the internal jute construction.

I think I got two rolls of the HR700 from the local Rod Shop for ~$40. So only ~$20 a roll. And yes, two rolls were needed for the roof, with about 1/3 of a roll left over which I will use on the rear package tray.
