Abstract
Unitary closure panels for automotive vehicles may be formed to have regions of different materials by a spray casting process. Separate sprays of different materials, for example two different metal alloys, are applied to touching regions of a spray application surface. The separate sprays may be applied sequentially or simultaneously to the forming surface to coat the respective regions so that the regions are contiguous or overlapping and a unitary body is formed. The spray formed body may be compressed and trimmed between facing surfaces to form a vehicle closure panel of specified outline, curvature, thickness, and porosity.
