My wifes bike is a painted titanium.
We were talking about it today and if the paint starts looking poor in the next few years, she's going to have the paint removed and go with the polished titanium that's under the paint.
Mine (Airborne Carpe Diem) is the typical titanium bike which I like it not having paint since I'm planning on using it for lots of dirt road riding which tends to do a number on paint finishes.
