How does one go about caring for exterior carbon fiber parts? :confused:

As far as I know, there's really not much special care needed for carbon fiber. You can probably wax it. You can put Dura Shine on anything, and that ought to be enough to keep it looking nice. I do know that it stands up to pavement better than urethane, and I've never seen discolored carbon fiber, so you probably shouldn't worry about it. The biggest clue is the fact that I've never seen any sort of "carbon fiber protectant" at AutoZone.
