This is probably the easiest modification for your car. There are a lot of ways to make a carbon fiber hood. 1) You can use a “Testors” flat black paint marker and just paint it. Use flat black because carbon fiber hoods are not real glossy. If you want it to look more realistic you can use a piece of screen and take a toothpick with gunmetal paint on it and dab it in each of the squares in a checkerboard pattern. 2) You can use a permanent marker and just draw on it. 3) you can find a picture of carbon fiber and just print it out on sticker paper to make decal or just buy a carbon fiber decal from a hobby shop (NOTE: A carbon fiber decal will not be to scale).
