Wow, you are really going into detail of paints! As you probably know I use Citadel's acrylic paints. I also got some Vallejo paints and they're quite similar. I don't know much about air-brush, but I' going to get into that, too, in some years...In any case I can recommend to you to spray-paint all your painted projects with a clear varnish.
Best regards from Germany!
