A composite part manufactured via a dual cast slush molding technique includes a skin layer having a first side and an opposite second side and a foam layer formed in situ on the second side of the skin layer. The first side of the skin layer defines a Class A surface. The skin layer and the foam layer each comprise a polymer of the same type and are respectively formed from a first resin-based composition and a second resin-based composition. The first resin-based composition and the second resin-based composition each may comprise a polyvinyl chloride (PVC)-based composition or a thermoplastic polyolefin (TPO)-based composition.
