Review on Siless 80 Mil (2Mm) 36 Sqft Car Sound Deadening Mat - Butyl Automotive Sound Deadener - Noise Insulation And Vibration Dampening Material (36 Sqft) by Youssef Coolidge

Clean clean clean. Vacuum, degreasing cleaners, and isopropyl alcohol. I took a wire brush to slight rust spots. Easy to cut. You will need lots of blades, I suggest getting a knife with snap off blades. Get multiple size width rollers. Take your time, and lay out in small sections. Pre fit and cut out any screws, nuts, bolts, plugs you may need access to in future before removing back paper. Most important wear thin gloves because the foil is sharp and you will contribute sweat, blood and tears to your project. I'm using 80 mil for trunk area and 200mil for the rest of car.
