I think the way that was applied was to spray a fog of rattle can spray adhesive into the air over some news paper, and wave the frame under the fog as it falls and collect on the frame work. Then apply the covering carefully and shrink lightly with hair dryer if necessary. That is the way I was taught to apply condenser paper and ultra light mylar covering for penny plane indoor models. Real sharp double edge razor blades to trim the edges or a fine tip soldering iron.
Type at you later,
