Works as Advertised

High quality sounds deadening material. I put it over some old Dynamat to get a little extra quiet. However, It’s a lot thicker than the 1/8” stated in the specs and has trouble sticking to edges. It covered the roof and floor of my extended cab. The thickness made reinstalling the headliner a bit difficult but overall it works. The difference was noticeable and worth it. Great bang for your buck for 40+sf.
