In case you were not aware, last year Squadron joined up with Scale Colors to release a line of paints that include sets as well as individual colors. These paints are acrylic and are best thinned with a 50–50 mix of water (I prefer distilled water) and isopropyl alcohol or using the Squadron Scale Colors Thinner (product SCW001). This set is designed for use with an airbrush, and I would highly recommend it.
