I'm in the process of doing a carbon fiber set of tins! The carbon fiber is not painted on, but it's not real carbon fiber, either! I'm doing the entire bike this way, both fenders, the tank, the sidecovers, the radiator shroud, and the headlight housing!
What you see here is JUST the beginning. I'm adding some "brushed aluminum" effects, and then I'll be spraying blue candy over all of it.
