Abstract: The present disclosure is directed to an automotive component and method of finishing such component including a polymer substrate, a tinted primer disposed over a first surface of the polymer substrate, a semi-transparent metallic coating disposed over the tinted primer. The semi-transparent metallic coating and tinted primer define at least one discontinuity. The automotive component further includes a top-coat disposed over the semi-transparent metallic coating and fills in the discontinuity. In aspects, the automotive component is back-lit and includes a light emitting source optically coupled to a second surface of the polymer substrate.

Abstract: A vehicle trim component, a vehicle including a vehicle trim component, and method of making a vehicle trim component. The vehicle trim component includes a substrate including a first polymer. The substrate includes a first surface, and the first polymer includes bisphenol-A based polycarbonate. The vehicle trim component also includes an exterior layer including a second polymer. The second polymer includes isosorbide-based polycarbonate. The exterior layer includes an exterior surface, and the exterior layer is laminated to the first surface of the substrate.
