Orion Assembly is using a paint system I do not recall any other automaker using, but correct me if I am wrong. They call it a "wet" system, in that the primer is covered by the color which in turn is covered by the clear coat, all wet before the next, then the oven to bake it all in one go. I could not tell if this lessens orange peel, mainly because it am rarely able to perceive orange peel even when it is pointed out to me, but it does lessen the number of times the body has to go through the oven, and that should be a good thing.
