OK it's simple hook. You paint the piece of whatever you're painting like a dark dark gunmetal. Black works too. Then you take some screen like from your back porch. After the black dries ALL THE WAY you want to take the screen and hold it on the piece very tight. Make sure your fingers are not in the way. Then you want to spray with the screen on it a shade of metallic grey. Like plain gunmetal. Make sure only to put one good mist coat. Not a real light coat but nothing near a wet coat either. Just a good lil' tsss tsssssss. You know. Then take off the screen and let it dry. Cheap and sometimes cheap looking but nothing beats free and something you did yourself. I also do this on the read fender on my race bike models. Even though it's barely noticable under the fender it's just nice to know it's there so if your friend sees it you can be like, "OH! CHECK THIS OUT MAN! I DID THIS CARBON FIBRE ALL BY MYSELF!!" and be the pimp of your neighborhood. Hope this helps and good luck. Email me if you need pics or whatever.
