Forget those instructions. You can buy "Raptor Sheen" from Hawkeye's Hobbies, on line. It is a paint additive. You mix it with Testor's Model Master Enamels and airbrush it on. I used light and dark ghost gray, with the Raptor Sheen additive. It's effect is subtle, but it looks good to me. Note, the Raptor Sheen additive is for Testor's enamels only, not Mr. Color or anything else.
