I found by following the recommended ratio of 10 drops of paint to 3 drops of thinner and 1-2 drops of ploy left the paint a little too thick for air brushing. The batch I mixed was based on 30 drops of paint and found that at least another 3-4 drops of thinner were required to thin out the paint for the proper consistency for air brushing. Once the right consistency the paint covered the model in a single light layer.
I use this paint almost exclusively on my models and model making. It goes on so nice just remember to put a little primer on first and then the colour trust me awesome sauce.
