120 Mil deadener from Jon @ Sky High Car Audio (Cool buddy and good business). I'm also giving you my honest opinion about the product. Ive used b stock second skin, Peel and Seal, Fat Mat, Dynamat, and extreme, NVX and a few other and so far Sky high is the heaviest and thickest. The quality is great, the foil is very thick and the back is very very sticky (I put my money on it being rubber vs asphalt/tar based. If your looking there are so many great brands. I went with SHCA for price per sq ft and thickness. Please leave the roofing products for the roofs of houses and buildings not your car. Trust me its not the same and you will need 3-4 layers to get the same results with more hassle. Hope this helps and is informative to some and entertaining to others. Peace and Bass!!
