Review on 🚗 Ninety-Mil Thick NVX SDBP40 Car Sound Damping Mat - 40 sqft. Butyl Automotive Sound Deadener for Audio Noise Vibration Insulation and Dampening (Ten 18” x 32” Sheets) by Javarie Malick

One of the thickest materials on the market. The odor is very low and the quality of the aluminum is high. I was able to roll it into fairly deep crevices without breaking the aluminum. I have coated my whole car twice and with half an inch of acoustic foam on top there is no radiant heat in my car other than the windows. No, it goes through my doors into my door panels from my roof to the headliner. My AC has to run a lot less to keep my cabin cool, it may have added 60 or 80 pounds to my car but the ceiling is worth it.
