12. All interior and exterior body painting is done via robotics, and most of the time it's done with the lights off. After all, the robots don't need light to see what they're doing, and eliminating them helps reduce GM's energy bills. Here you can see a body entering the main color booth. The GM team turned the lights on for us so we could get a photo. One of the main benefits of robots in painting is that they apply the paint the same way to every vehicle, thus the finish is impeccable and consistent. From here, the bodies travel through a few more processes including baking and clearcoat.
