I understand the cool factor of showing off the carbon fiber. I would get tired of that fast.
We took a tour of the Dallara Indy car factory a coupe of weeks ago. They make ALL the Indy cars now, and several of the LMP cars and they don't brag much about it, but they also built the HAAS F1 cars. They know Carbon firer.

Cool facility.
It is never going to be a decision I have to make, to paint my carbon fiber car or leave it exposed.
