A method is provided for manufacturing an upper reveal that conforms to a curved portion of a window opening of a motor vehicle door frame. The upper reveal is formed from TPV and a carrier. The method includes the steps of: co-extruding the TPV with the carrier; curing the TPV to form the upper reveal; heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV; and bending the upper reveal to conform to the curved portion of the window opening of the motor vehicle door frame.
