All very good points. You could rock it for a little while carbon, then painted it once it started to fade. Sure it won't be paid by insurance then, but so what, painting a hood isn't that much.
I wouldn't paint it all because of other peoples cars. Yeah I'll admit it's played. But so are so many other trends. I would drop all other considerations and just look at what you like the look of more. Then pick that. In the end your building the car for yourself and no one else.
