Nothing in the ads indicated that the titanium was just a crisp, thin sugar shell. Rather like advertising an item as "gold" when it is really zinc with gold plate. The titanium may well be the very best coating ever applied to a Leica, but if I buy a "titanium" watch, the case is actually made of titanium, not just painted with titanium, and the ads from Leica mirrored the watch ads at the same time and led one to believe that the titanium was a construction material and never revealed that it was merely a coating. In the circumstances I think Titanized is appropriate and probably preferable to "cam sham scam".
