Description

The HushMat 1978-1987 Buick Regal Firewall Kit is a sound deadening and thermal insulation material designed for classic cars. It effectively reduces heat transfer from the engine, headers, and exhaust into the vehicle's interior, making for a more comfortable ride. The kit also works to reduce road and exhaust noise, creating a quieter cabin environment. HushMat Ultra is a pressure-sensitive, constrained-layer damper with excellent adhesion properties.
