I started with the dark gray and blue Air Force version. I did use some automotive spray-can gray primer over the dark blue areas, I don't think I primed the entire airplane, but it won't hurt.

The Testors paint didn't eat any foam on my plane, and I have used it on bare foam on other planes. It dries pretty quick. Try it on an area you won't see after the plane is finished to make sure.

I paint my planes like any other models, several light coats to achive the color desired, rather than one or two heavy coats which would likely have runs. Give primer time to dry completely before covering it, and give paint time to at least get tacky before the next coat.
