A method of preparing a vehicle panel assembly (10) for attaching the panel to a vehicle is disclosed which provides a "ready-to-install" panel assembly. The panel assembly (10) includes first and second spaced sides (14,16), with the bead (26) of heat activated adhesive provided on the second side (16) of the panel. The panel (12) and bead (26) are heated preferably by applying shortwave and longwave infrared radiation, with the shortwave infrared radiation being applied to an adhesive free side (14) of the panel (12) to heat the panel and, thereby, indirectly heat the bead of the heat activated adhesive. The longwave infrared radiation is applied to the adhesive side (16) of the panel (12) to directly heat the bead and thereby activate the adhesive. The ready-to-install adhesive may be applied on or adjacent to a gasket, such as a polyvinyl chloride (PVC) molding, a urethane molding, or the like. Optionally, either during or after heating, the substrate is cooled in order to ease handling of the panel assembly after the bead of adhesive is activate and ready for installation. <IMAGE> |
