Nice product. With adhesive applied, this an all in one product. Easily cut to random shapes and dimensions and the adhesive seems to hold well. Removing the paper that protects the adhesive to apply in tight areas, presents a new set of problems. Having applied the product inside the panels of an old Trooper, it is yet to be determine if sound and temperature transfer are reduced.
