A method ( 10 ) includes the steps of placing an insert ( 12 ) into a mold cavity ( 20 ), molding an insulating layer ( 30 ) of a homogeneous and continuous composition ( 28 ) over the insert ( 12 ). The next step includes placing the insert ( 12 ) with the insulating layer ( 30 ) into a second mold cavity ( 36 ) followed by the step of molding the part ( 46 ) of a homogeneous part composition ( 44 ) over the insert ( 12 ). The insulating layer ( 30 ) is disposed between the insert ( 12 ) and the part ( 46 ) and bonded thereto. The method ( 10 ) includes painting the part ( 46 ) wherein a paint ( 48 ) is injected into the second mold cavity ( 32 ) over the part composition ( 44 ). Flexible properties of the insulating layer ( 30 ) adapt to the differences between coefficient of thermal expansion of the part ( 46 ) and the insert ( 12 ) thereby eliminating problems of potential cracks, sink-marks, and the like.
