Claim:
A method for placing a resin layer on a selected surface of a metal frame member of an aircraft, the method comprising the steps of: (a) providing an overpress having an inner surface with a plurality of nubs protruding therefrom; (b) placing liquid resin on one of the surfaces of the overpress or the frame member; then (c) forcing the nubs of the overpress in contact with the selected surface of the frame member, causing the liquid resin to spread across the said one of the surfaces and allowing the nubs to define a clearance between the overpress and the frame member that fills with the liquid resin; then (d) allowing the liquid resin to cure into a layer of cured resin that bonds to the frame member, then removing the overpress from the selected surface of the frame member and the layer of cured resin; and (e) leaving the layer of cured resin bonded to the selected surface of the frame member, the layer of cured resin having hollow spaces where the nubs previously were located.
