A method of repairing breaks in plastic sheet members such as those used on dashes of automobiles. The abutting edges of the crack formed at the break are coated with a liquid cyanoacrylate adhesive. The crack is filled with a particulate material, preferably hardened polyurethane foam or graphite which has been ground to a particle size corresponding roughly to that of common table salt. The particulate filler is soaked with the liquid cyanoacrylate adhesive and the liquid is then dried. For cracks of substantial depths, several layers of filler soaked with the adhesive may be utilized to completely fill the crack. After the filler composition has completely hardened and the repair smoothed by sanding, the immediate zone may be textured by spraying with a liquid vinyl lacquer. When the lacquer is dry, the region may be painted to blend with the remainder of the member.
