Customers love the glossy, colorful finish coat on the outside of a car, but that coat is expensive and hard to apply on the inner surfaces of trunk or hood compartments. PPG has pioneered a process that applies high-gloss colored powder primer designed to match the final exterior color of the vehicle. A 10-color primer palette allows close color matching. The result improves aesthetics while saving money by allowing a single primer application with less film buildup. More intricate, detailed areas such as the in-trunk hinges can now be painted. Reclaimed powder from the paint line can be reused, meaning no volatile organic compound release, no paint sludge or hazardous material disposal. The process was first used on the 2005 Chevrolet Cobalt at General Motors' Lordstown, Ohio, assembly plant.
