Abstract
Abstract The specification discloses a method and a kit for repairing surfaces, particularly vehicle surfaces, in which the surface to be repaired is covered by adhering a plastic sheet having beveled edges thereto, followed by sanding the beveled edges and adhering sealant to at least the visible edges, feathering the sealant so as to create a smooth surface, followed by painting the repaired area.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
272 words
A method for repairing an area of a vehicle body comprising: providing a thin sheet of stock plastic of sufficient size to cover the area to be repaired, said plastic sheet has a thickness of from about 20 mils to about 40 mils, said plastic sheet being sufficiently pliable that it can be manually shaped to conform generally to the area to be repaired, but sufficiently rigid to resist oil canning, denting and other localized deformation; cutting and shaping said plastic sheet to a size that it extends between ornamental deviations in the otherwise smooth surface of the vehicle being repaired whereby the edges of said plastic sheet are not as readily apparent to view; preparing the area of the vehicle to be repaired by making sure it is reasonably smooth and free of excessive flaking rust; manually shaping said plastic to conform generally to the area to be repaired; beveling the edges of said plastic sheet before said plastic sheet is adhered to the area to be repaired; adhering said plastic sheet to the vehicle area to be repaired with an adhesive; said method further including sanding the beveled edges of said plastic sheet to further effect blending with the vehicle surface after said plastic sheet is adhered to the area to be repaired; applying a sealant to at least the visible edges of said plastic sheet, feathering said sealant to create a smooth flowing surface from the surface of said plastic sheet to the surface of the vehicle, said sealant being of a material which dries firm, but resilient whereby cracking is minimized; painting the repaired area of the vehicle.
