Does your engine and exhaust drone, road noise and vibration in your car drive you nuts? Is it so noisy inside you have to crank up the stereo or shout to have conversations? What about the heat radiating in from the engine, headers, floor, firewall, tunnel, exhaust and catalytic converter? Fix all these problems with the HushMat Ultra Super Bulk Sound Deadening Kit with Stealth Black Foil! HushMat is super-easy to install because it is self-adhesive, does not require special tools, surface prep or any adhesives, nor will it contaminate spray operations. And you can use it in firewalls, floor pans, tunnels, doors, roof, rear wheel wells, trunk and quarter panels. HushMat Ultra is a pressure-sensitive, constrained-layer damper, which has excellent adhesion to many difficult to bond substrates such as oily cold rolled steel, automotive E-coat, primers and finishes plus many plastics including polypropylene. The aluminum foil constraining layer and specially formulated visco-elastic polymer layer combine to give effective vibration damping over a wide temperature range. HushMat is the only OEM specified and approved sound deadening and thermal insulating material available to the automotive aftermarket. This kit contains 9 sheets of 18 in. x 32 in. Stealth Black Foil for 36 sq. ft. of coverage.
