I'm impressed. I've loved this kit since I was a kid in college. Still have a 1/48th scale one with an old PE set made for it. That and the 'Stingbat" stealth attack helicopter are a couple of the neater kits produced. Revell's B2 Stealth bomber and the Testors SR-71 replacement are other futuristic kits I own.
I painted my original F-19 in all black in the 1980s, but when I built it again, it'll be in the "Air Superiority" gray scheme the directions also give.
