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.
