A method of preparing a vehicle panel assembly for attaching the panel to a vehicle is disclosed which provides a “ready-to-install” panel assembly. The panel assembly includes first and second spaced sides, with the bead of heat activated adhesive provided on the second side of the panel. The panel and bead are heated preferably by applying shortwave and longwave infrared radiation, with the shortwave infrared radiation being applied to an adhesive free side of the panel 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 of the panel 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.
A method of preparing a vehicle panel assembly for attaching the panel assembly to a vehicle, the vehicle panel assembly having a substrate and a bead of ready-to-install heat activated adhesive, the substrate having first and second sides and a peripheral portion, the bead being applied to the second side of the substrate and including a central core portion, an outer skin portion, and an interface portion on the second side of the substrate, said method comprising the steps of:
The method of preparing a vehicle panel assembly for attaching the vehicle panel assembly to a vehicle, the vehicle panel assembly having a substrate and a bead of the heat activated adhesive, the substrate having first and second sides and a peripheral portion, the peripheral portion including a gasket formed thereon, the gasket extending over at least a portion of the second side of the substrate, and the bead of ready-to-install heat activated adhesive being applied to the gasket, the bead including an interface portion on the gasket, a central core portion, and an outer skin portion, said method comprising the steps of:
