Method of adhering an object to the exterior of a motor vehicle
View Patent ↗Dissolving paper ( 22 ) covers pressure sensitive adhesive ( 20 ) on a mounting face ( 18 ) of an object ( 16 ) to be mounted on an exterior surface of a body panel ( 10 ) of a motor vehicle by a mechanical fastening system ( 24 ). The mounting is exposed to a water wash. Water begins to be absorbed by the dissolving paper through the edge of the paper's outer perimeter. As the paper increasingly absorbs water, it dissolves in the water exposing the adhesive which then adheres to the panel.
1. A method for mounting an object on a motor vehicle body, the method comprising:
using a mechanical fastener to mechanically fasten the object to the body to place a mounting face of the object that contains pressure sensitive adhesive in confrontation to an exterior surface of the body but separated from the exterior surface of the body by a layer of dissolvable paper; and
then wetting the dissolvable paper with a solvent to cause at least some of the paper to dissolve and expose underlying pressure sensitive adhesive, and as a consequence, to cause the exposed pressure sensitive adhesive to come into contact with the exterior surface of the body.
2. The method as set forth in claim 1 wherein the step of using a mechanical fastener to mechanically fasten the object to the body to place a mounting face of the object that contains pressure sensitive adhesive in confrontation to an exterior surface of the body but separated from the exterior surface of the body by a layer of dissolvable paper comprises creating tension in the object, and the step of wetting the dissolvable paper with a solvent to cause at least some of the paper to dissolve and expose underlying pressure sensitive adhesive, and as a consequence, to cause the exposed pressure sensitive adhesive to come into contact with the exterior surface of the body comprises causing the exposed pressure sensitive adhesive to come into contact with the exterior surface of the body by a slight release of tension in the object that was created when the object was mechanically fastened to the body.
3. The method as set forth in claim 1 wherein the mounting face of the object comprises a resilient layer on which the pressure sensitive adhesive is present, the step of using a mechanical fastener to mechanically fasten the object to the body to place a mounting face of the object that contains the pressure sensitive adhesive in confrontation to an exterior surface of the body but separated from the exterior surface of the body by a layer of dissolvable paper includes causing compression of the resilient layer, and the step of causing the exposed pressure sensitive adhesive to come into contact with the exterior surface of the body comprises resiliency of the resilient layer aiding in forcing the exposed pressure sensitive adhesive to adhere and seal to the exterior surface of the body.
4. The method as set forth in claim 1 wherein the step of causing the exposed pressure sensitive adhesive to come into contact with the exterior surface of the body comprises causing the exposed pressure sensitive adhesive to seal a perimeter margin of the mounting face of the object to the exterior surface of the body.
5. An object for mounting on an exterior surface of a motor vehicle panel comprising a mechanical fastener for fastening the object to the panel to force a mounting face of the object against the exterior surface, and a pressure sensitive adhesive on the mounting face that is covered by a thin layer of dissolving paper that will dissolve when wetted with a solvent to expose the adhesive and allow the adhesive to adhere to the exterior surface.
6. The object as set forth in claim 5 wherein the object comprises a resilient layer on the mounting face containing the pressure sensitive adhesive.
7. The object as set forth in claim 6 wherein the pressure sensitive adhesive is disposed only on a perimeter margin of the mounting face and the dissolving paper comprises a strip covering only the adhesive.
