Yes, you can paint CF Hoods.....I think they look best with a light paint sprayed over them....its when from far away it looks like the color of the car....but up close you can tell its a CF Hood and can still see the fibers

Another thing I have seen instead of hood pins is there are things out like hood locks or body locks....I forget who makes them but they sit flat and flush with the hood and you can paint them black so they aren't noticeable as much.....I was thinking of doing all this on my burgandy 4thgen but $$$ ya know....good luck
