Floquil old silver first, then mask off various panels and spray on Floquil bright silver. I've been using this system for almost 20 years and am very pleased with the results I get. The paint is tough and I've never used primer. Unfortunately, Testors stopped making Floquil a while back, but I stocked up on it back then and still have a few bottles of it stashed away. Wish I had done the same with the original formula Future.
