A multilayer window guiderail is disclosed. The window guiderail includes a rail portion having an outer edge, a rail surface and an opposing rear surface. The rail portion includes a core and an integral rail cover layer disposed on the core. The core includes a first polymer material and the rail cover layer includes a second polymer material. An apparatus for making a multilayer guiderail includes a plurality of die portions having respective cavity portions. The cavity portions are configured to define a die cavity having the shape of the guiderail, at least one of the die portions being a slidable die portion and at least one of the die portions being a fixed die portion. The parting surface of the slidable die portion is configured for sliding translation of its parting surface over the parting surface of the fixed die portion along a translation path.
