Factory Trunk Deadner

That green trunk does look nice but I prefer a factory style painted surface. The back sides of the quarter panels are slathered with the thick stuff, that is fine with me.
Resto Rick sells gallons of the thick sound deadener. It goes on with a "Shutz" type gun. The closer you are to the panel, the flatter the material lays. Further out, it lays in a speckled form.
