One shader that I have always felt was missing from the pack is a dull metal shader, the sort of thing that you would find in the engine compartment, old exhausts, underside of the car, etc. I have always used textures for this, like this one, but it would be nice if there was a cool shader similar to this. I have procedurals for various gun metals, but they are not quite duill enough for the things I need.
