Lloyd, I can't equivocate clothes' colors fading in sunlight with case-hardened colors fading. One's colored with dye. The other is not colored with anything. The colors we see on the gun is a prismatic effect. For sunlight to change what the eyes see, on a case-hardened surface, the photon bombardment Ryan speaks of would have to physically change the structural shape of the tiny prisms.
Can that occur? IDK. Basic physics never taught ME that. Heck, as old as I am I'm not even certain photons had been discovered when I last sat through a physics class. š¤£
