Review on 🚗 uxcell 10pcs 80mil 25sqft Car Sound Deadener: Effective Heat Insulation Mat Pad for Damping, Self Adhesive Deadening Material for Door Roof Sound Barrier - Black by Matthew Fadoul

For the price, the 80 mil 25 square foot Uxcell car muffler is a good deal. The panels are very heavy and come with a backing paper which needs to be peeled off before sticking to a cleaned metal surface. As others have said, other brands offer better adhesion. My caliper battery died, so I couldn't test the claimed 80 mil thickness.
