Even if you’re using airbrush paints, you’ll need some thinners. Thinners help to ensure your airbrush doesn’t clog up and make cleaning easier. You may find that you need to thin your paints a little more due to the conditions on the day (airbrushes can be temperamental beasts). This thinner can also be used to thin Vallejo Game Color and Model Color paints for use in your airbrush.
