Ballistic sound dampening material is an elastomeric butyl and aluminum layered vibration dampener that conforms and fuses easily to sheet metal and other hard surfaces.
Ballistic greatly reinforces the interior of the Door, Floor, or Trunk and reduces vibrations and road noise
Properly applied Ballistic will even help prolong your speakers life by diminishing exposure to moisture and helping to stabilize tempters
Relatively odor free, designed to eliminate the smell issue without sacrificing effectiveness.
Perma Stick allows Ballistic to adhere to almost any surface. The better your sound dampening material adheres the more effective it will be.
