85 GMC Sierra "Scarlett"

[N2TRUX]

Last night I squeezed a couple of hours of shop time in. Chris had helped me pull the headliner so I focused on making the inner skin acoustically dead. Research tells me it's not necessary to cover the entire panel so I tested that theory.Since the liner board is a tight fit around the perimeter, I concentrated on the center mass areas. I was very pleased with the results.

My thump test reveled that the roof skin now has the same dull thud when tapped with my knuckle as the rest of the truck. I plan to insert a thin foil liner to add additional heat resistance as well.
