The advantages of this color system: Colors in 18 ml containers are ideal for processing. The colors can be diluted with water and have a mild odor. They are non-flammable and contain virtually no organic solvents. There are 88 different colors that can be mixed together. The paint dries completely in 2 to 3 hours. You can repaint over a color after just one hour, which is 6 times faster than with enamel colors. These colors and the enamel colors (14 ml) can be easily painted over each other after the drying time is respected, but they should not be mixed together. The paint is also suitable for airbrushing. It is important to note that the paint should not be diluted too much, with a maximum of 20 to 25% water. It is optimal to dilute the paint with Aqua Color Mix, as it acts as a drying retardant and prevents the paint from drying too quickly in the spray gun. The spray gun should be cleaned immediately with water after use. If the paint has already dried, the spray gun can also be cleaned with Airbrush Clean or Aqua Color Clean. For brush application: The colors are brushable and have high opacity. Smooth surfaces after brushing are almost as good as when airbrushing. The end result is absolutely comparable to enamel colors. Exceptional results when brushing.
