ABSTRACT:
A vehicle spoiler includes a first rigid body part having an external surface contour, a second resiliently deformable foam body part having an external surface contour complementary to the first surface contour, and means for integrally securing the first and second body parts together. Preferably, the deformable foam body part is molded in situ on the rigid body part. A finishing groove extending between adjacent edges of the first external surface contour and the second external surface contour prevents recognition of differences between the materials and processes used to form the first and second body parts and prevents inconsistent transition between the body parts. A method for forming the spoiler includes fabrication of injection molded body shell parts bonded together by a foam material to form a rigid first body section. The rigid body section is then positioned within a molding cavity while foam material is introduced into the cavity and against engagement surfaces on the rigid body part.
