A skin layer for covering a dash panel structure in overlying relation to an air bag cushion assembly. The skin layer is of a multi-layered construction including a top layer of virgin polymeric material forming a show surface of controlled predefined color across the vehicle dash panel and an underlying layer of regrind material formed from the scraps of material generated during molding and trimming of the dash panel covers. A tear seam may be scored across the underside of the skin extending into the underlying layer of recycled material in a desired break-out pattern for the air bag cushion. The skin layer may be disposed across an underlying layer of foam which in turn is disposed across a supporting panel structure.
