Snake is right! Don't use Fusion on models, but the regular Krylon "Colormaster" (couple bucks a can cheaper)works good. Even though the can says paint&primer, I still use Krylon primer with it.
I usually use the cheap paints on the interior, chassis, and engine, and use Tamiya or Testors lacquer on the bodies, but I have used Krylon on a few bodies too, and it works fine.
