Just make sure that you get a good quality CF hood. If you have one that looks wavy (the resin) your paint will look that way. DGmotorsports hoods are nearly flawless and would be a good one to paint. But yes you can paint them with not problem.
paint parts of it is the point i think.... like on the wings west Mp3 the sides of the hood are color matched. thats the way ill paint my hood too if i ever get one
Since anyway, 99.9% of carbon fiber accessories sold in the U.S.A. are "clear coated" with resin or similar products, and from what I've seen, these coatings are similar to paint in thickness, so if you paint your C.F. hood partially or totally, it will very probably weight as much as without any paint but the original clear resin coating.
