Featured Build: 1967 GMC C10 Sound Deadening

MAC's garage GMC C10 Build

This 1967 GMC C10 came into Mac's garage with deadener that Mac says "smells like someone is getting a new roof inside the cab". We ran across this build pre-removal stage and suggested to Mac that he use dry ice and alcohol in a bag to remove the old stuff. Once that was accomplished, they reached out to us for some American made Damplifier Pro butyl sound deadening (about 36 sq ft). The truck floor is about 20 sqft and the back wall about 8 sqft. It took 18 sheets of Damplifier Pro to completely cover the floor and back wall.
