Abstract
Abstract This invention relates to a method for repairing plastic materials, and more specifically, automobile dashboards and the like. The method enables one to provide the repaired item with a texturized finish such that cracks, cuts, and other imperfections in the surface are completely covered in such a manner that the repaired item appears to take on the appearance of being new. The method comprises the steps of filling in cracks and other indentations with a hardenable filler such that a smooth surface is formed. A base coat of an acrylic resin is then applied over the surface followed by a texturized acrylic resin coating which forms a texturized finish on the surface. Depending on the original color of the item to be repaired, a thin colored coating may be applied over the texturized finish so as to form a continuous colored texturized finish over the entire surface of the now-repaired item completely masking the cracks and other imperfections in the surface thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
140 words
A method for repairing automobile dashboards and like plastic items having a texturized surface so as to provide the repaired areas with a surface substantially identical in appearance to the original surface, comprising the steps of: (a) filling in cracks and other indentations with a resinous filler such that a smooth surface is formed; (b) applying a base coat of an acrylic resin lacquer over the area having the now-filled cracks and indentations; (c) applying a texturize-producing resin coating over said base coat so as to form a texturized finish on the repaired area which is substantially identical in texture to the surface of the item being repaired; and (d) applying a thin coating having a coloring agent over said texturized finish so as to form a continuous colored texturized finish over the entire surface including said cracks and indentations.
Claim 2
Independent Claim
140 words
A method for repairing automobile dashboards and like plastic items having a texturized surface so as to provide the repaired areas with a surface substantially identical in appearance to the original surface, comprising the steps of: (a) filling in cracks and other indentations with a resinous filler such that a smooth surface is formed; (b) applying a base coat of an acrylic resin lacquer over the area having the now-filled cracks and indentations; (c) applying a texturize-producing resin coating over said base coat so as to form a texturized finish on the repaired area which is substantially identical in texture to the surface of the item being repaired; and (d) applying a thin coating having a coloring agent over said texturized finish so as to form a continuous colored texturized finish over the entire surface including said cracks and indentations.
Claim 3
Dependent Claim
15 words
A method according to claim 1 wherein said hardenable resinous filler comrpises an epoxy resin.
Claim 4
Dependent Claim
20 words
A method according to claim 1 wherein said resinous filler is sanded prior to the application of said base coat.
Claim 5
Independent Claim
146 words
A method for repairing cracks and cuts in automobile dashboards and like items having a flexible plastic skin and a semi-rigid foam core comprising the steps of: (a) depressing said skin and said foam core in an area surrounding each said crack and cut so as to form an area which can be filled in; (b) filling in said cracks and cuts and said area surrounding the same with a hardenable resinous filler; (c) smoothing said resinous filler so as to match the original contour of said item to be repaired; (d) applying a base coat of an acrylic resin lacquer over the area having the now-filled cracks and cuts; and (e) applying a texturize-producing resin coating over said base coat so as to form a texturized finish on the repaired area which is substantially identical in texture to the surface of the item being repaired.
Claim 6
Independent Claim
146 words
A method for repairing cracks and cuts in automobile dashboards and like items having a flexible plastic skin and a semi-rigid foam core comprising the steps of: (a) depressing said skin and said foam core in an area surrounding each said crack and cut so as to form an area which can be filled in; (b) filling in said cracks and cuts and said area surrounding the same with a hardenable resinous filler; (c) smoothing said resinous filler so as to match the original contour of said item to be repaired; (d) applying a base coat of an acrylic resin lacquer over the area having the now-filled cracks and cuts; and (e) applying a texturize-producing resin coating over said base coat so as to form a texturized finish on the repaired area which is substantially identical in texture to the surface of the item being repaired.
Claim 7
Dependent Claim
15 words
A method according to claim 4 wherein said hardenable resinous filler comprises an epoxy resin.
Claim 8
Dependent Claim
41 words
A method according to claim 4 wherein said method includes the step of: (f) applying a thin coating having a coloring agent over said texturized finish so as to form a continuous texturized finish of a predetermined color on said skin.
Claim 9
Independent Claim
151 words
A method for repairing automobile dashboards and like flexible plastic surfaces having a texturized surface so as to provide the repaired area with a surface substantially identical in texture to the original surface, comprising the steps of: (a) filling in cracks and other indentations in said plastic surface with a resinous filler such that a smooth surface is formed; (b) applying a texturized producing acrylic resin coating over the area having the now-filled cracks and indentations so as to form a texturized finish on the repaired area which is substantially identical in texture to the surface of the item being repaired, said texturize-producing acrylic resin coating comprising polymethylmethacrylate in a solvent mixture of isopropyl acetate, toluene, acetone and xylene; and (c) applying a thin coating having a coloring agent over said texturized finish so as to form a continuous colored texturized finish over the entire surface including said cracks and indentations.
Claim 10
Independent Claim
