I saw on another site that plain old "Krylon Matte Finish" rattle can paint is actually really good. And you get a life time supply for 4-5 bucks. Trick is to spray it thu a 5" straw into a empty jar that works with your airbrush. It will fill up a 1/2 or 1 oz jar pretty quick. Don't know about you folks, but over the decades I have spent 100's of dollars on flat clear paint in those little bottles. This is so far, the best I have ever used. It goes on a bit thick right from the can on a model I think. So spraying into an airbrush application is best IMHO. Let us know what you think.
