Ballistic license plate frame with sound dampening and foam gaskets. Relatively odor free. There's nothing worse than having sound dampening material installed in your car, only to get inside and your car smells like a road paving project. Ballistic was specifically designed to eliminate the smell issue without sacrificing effectiveness. In addition to developing the thickest, densest material on the planet our engineers created a new adhesive, Perma Stick. Perma Stick allows Ballistic to adhere to almost any surface. The better your sound dampening material adheres the more effective it will be.
