The advantages of this color system: Revell Aqua Color paints come in completely new 18 ml containers that are ideal for application. The paints are water-soluble, low-odor, non-flammable, and contain virtually no organic solvents. There are 88 different colors that can be mixed together. After 2 to 3 hours, the paint is fully dry, and re-coating is possible after just one hour, which means it dries six times faster than enamel paints. The new colors can be easily layered over the existing enamel paints (14 ml) after drying, but they cannot be mixed together. The paint is also suitable for airbrushing. It is important to note that the paint should not be overly diluted, with a maximum of 20 to 25% water. Ideally, the paint should be diluted 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 started to dry, the spray gun can also be cleaned with Airbrush Clean or Aqua Color Clean. For brush application: The paints are easy to apply and feature high opacity. They leave smooth surfaces after brushing, almost as good as airbrushing. The final result is absolutely comparable to enamel paints and offers exceptional results when brushed.
