Oddly enough, I'm not a huge fan of spraying with Model Air, but I love brush painting with them, especially their dark greys for detail painting in cockpits etc. It's thinned to just the right consistency that I like so I can literally put a drop down and paint straight away. I do use a lot of their model colour paints, but now that I've discovered my love of brush painting the model air variety, I'm not sure I'll be buying any more.
