Dynamat

SPL competitors, here's the real deal! Designed to maximize Sound Pressure Level, Dynamat's Dynaplate is the ultimate vibration killer — an extremely thin, super-lightweight (0.16 pounds per sq. ft.) damping material, with a pressure-sensitive adhesive for easy installation. A two-layer application of Dynaplate structurally reinforces your car body panels for maximum SPL, eliminating the "ballooning effect" common in SPL vehicles. If your goal is low weight and extreme performance, Dynaplate is your best sound damping choice. One sheet covers an average-sized door. (This kit includes three 24" x 30" sheets totaling about 15 square feet.)
