A method of bonding a cured plastic member to a reinforcement member, said method comprising: forming an assembly by placing an uncured thermosetting adhesive between mating surfaces of the cured plastic member and the reinforcement member; placing the assembly between two electrodes, one of said electrodes including a plurality of electrically isolated concentrator members; and applying a high frequency signal having a frequency of between about 10 megahertz to about 110 megahertz at a voltage of between about 300 to about 8000 volts to the electrodes from a dielectric heater for a period of time from about 15 seconds to about 120 second which is sufficient to cure the adhesive, said concentrator members providing even concentration of energy from the high frequency signal at selected areas of the adhesive such that the plastic member is bonded to the reinforcement member without substantial adverse affect to the surface quality of the plastic member.
