This is great stuff! Already thinned, the only thing you have to do is give it a little shake and pour it in your spray gun or airbrush. This is also one of those times where you should follow the Mfg. instructions by using this as a base for their metallic paints. Besides working great, the metallic colors are also lacquer based, so if you go putting the metallic color over an enamel, you're inviting problems. I will be getting more without hesitation!
