Vallejo Model Air is good paint for you then since its all you can get. They work well out of the tube, but if for some reason you got some older tubes and its comes out thick you can thin it with some water of if they have a thinner for those paints.
i havent used all colors from them, but the ones i have used seemed to work out fine. You can even use their paints on small brushed to do detail work too (like eyes, lips etc..)
As for clogging a airbruh, that all depends on your model too. Some airbrushes tend to clog no matter what paint is used. But i haven't see Val paints clog my brush to much.
If you can get your hands on this Windsor newton brush cleaner, its great for pushing some thru your airbrush to clean any caked on paint.
