ABSTRACT:
A process for refinishing the surface of a body of acrylo-butadiene-styrene (ABS) polymer by applying to the surface a coating material and treating the body with a solvent. The surface is cooled, together with at least the material underlying the surface, to a temperature in the range about 32.degree. F. to 40.degree. F. The surface of the body is then contacted with a solvent vapor for a time sufficient to reflow the surface but not to warm appreciably the inner layer of the body. The process avoids distortion in the refinished surface.
