Thinning craft acrylics can be a tricky proposition! I have been reading about all these forums from model rocketry, model railroad, and model builders in general. For the most part they all swear about using Future Floor polish as both a clear coat on finishes, as a barrier between two different kinds of finishes, and more imporantly as a flow improver and thinner for acrylic paints.NOTE=Future Floor polish is now called Pledge Floor Care with Future shine. It is the same products and still works great.I will discuss primarily the results of putting mixtures of the paint with the Future to thin with the additional help of a little water. In the photo shown here, I have a mix of blue metallic paint mixed with an equal volume of Pledge Floor Polish with some water. As you can see it worked OK but I would like to mention that your paint MUST be like skim milk WITHOUT any lumps! Otherwise the airbrish will just clog up every 20 seconds and you will be doing more cleaning than painting.After repeated ventures with this stuff it is a great all around reducer for most types of acrylic paints. Sometimes I even use it neat without water to reduce paint. It did well with the thicker Createx airbrush paints and they came out smoothly.

It should be mentioned that there are a number of other unexpected materials that are use with various levels of success. I would also like to comment on the comparison of these in contrast to acrylic media designed for blending with paints.
