ABSTRACT:
A process for repairing surface defects in plastic articles, especially plastic articles formed from fiber reinforced thermosetting resins, includes the steps of applying a powder coating composition to a defective area on the surface of a plastic article, curing the applied powder coating composition through the application of heat, and removing excess cured powder coating composition from the area of the defect to conform the area of the defect to the proper contours of the plastic article. The process can be utilized for repairing surface defects such as porosity, scratches, gouges and sand-through areas of cured thermoset substrates such as automotive body panels formed from sheet or bulk molding compounds.
