Clean the body really well. take drywall tape and put it over the area you want to look like carbon fiber then spray gray, peel the tape off and spray black. if you want a little more realistic look then instead of gray then hit it with back very lightly. go over the black with root beer then back with silver, peel the tape and finish with black. (Note: You will not get it right the first time so practice on some scrap lexan and be light with the root beer it will beed through other colors if laid down to heavy)
