Abstract
Abstract A method of applying a prepainted carrier film to an automobile body part in a vacuum thermoforming process. The prepainted carrier film has a top surface painted by a color coat formulation not containing any flakes and then coated with a layer of clear coat having a thickness of no less than 10 microns. The prepainted carrier film is heated and stretched in a vacuum thermoforming process and then assembled to a substrate for an automobile body part by adhesive means. The clear coat layer retains substantially the same gloss and color appearance of the stretched prepainted carrier film as prior to the such stretch.
