Summit has a roof insulation for $20 to fit a 60-70 Hard top ford, the blackened fiberglass is pattern pressed on one side for glue, it's two pieces 1"x 18.5" x 48". I don't have to remove the back window, the teeth are available with a smooth plastic tool. Who said to do that? ( a painter) The manual I have said to start at the front bow and work back to the roof hooks. Then stretching towards the front teeth. Then the sail panels and door trim. Use Permatex white headliner adhesive to hold up the insulation and edge work.
