Interesting, I saw a Salsa frame that had this treatment and after two years with just a clearcoat it was still fine. Except of course where the clearcoat had come off. The frame had been sandblasted and treated before the clearcoat, so I wonder what the "treatment" was? Classic content is Ross Schaffer designs and builds, or did build and design, in a truly "classic" style. I also remember some of his early MTBs being just as light as many sport/touring bikes. enjoy, Brandon"monkeylad"Ives
