Im supposed to apply a light coat of clear blue ( Tamiya enamel) on a clear window part of a helo im building; previously, i was able to do so by brush without producing brush stroke marks; however, this time, after adding some thinner to dilute the partly hardened paint, to my horror, the brush strokes appeared! the clear blue has a rather different consistency than standard enamel paints; my question is can i airbrush this reformulated clear blue i am using?
