Dynaplate is the Sound Choice Dynaplate is a constrained layer damping material that structurally reinforces your car body panels for maximum sound pressure level. Using only a two-layer set-up yields non-flexible panels that prevents the “ballooning effect” common in SPL vehicles. Installation Dynaplate should be cut to the desired size before the release liner is removed. Remove dust, grease, moisture, and other foreign matter from the application surface. Peel off the release liner and place on desired area. Highlights Constrained Layer Damping Material Reinforces Body Panels Maximum Sound Pressure Level (SPL) Peel-And-Stick Application
