I just checked a Ferrari Two Face and they are not printed. The logo is definitely etched. That must be some strong ass cleaning to wipe off that etching.Sorry to double post ... BUT! if you double click his picture and zoom in you can tell from the lenses they've kinda been thrown around and are definitely considered in USED condition. That being said it almost does look like a very faint FERRARI logo in the bottom right that has perhaps worn off over time from cleaning and just being thrown around. I almost can see it there. I honestly can't remember whether it is cut into the lens or screen printed on like their OAKLEY logos on some glasses. I'm guessing it's printed on and it has worn off. If you know they're real ... call Oakley customer service and explain and send them pics. And ask them, how could aluminum rust? Their site says aluminum, not C-5 Alloy. If it's their C-5 Alloy then that is a combination of metals, so technically that could potentially rust.
