Revell Aqua Color paints come in new 18-ml containers and are ideal for use. These paints can be diluted with water, have a mild smell, and are non-flammable. They contain practically no organic solvents and offer 88 different colors. The paints can be mixed with each other and are completely dry after 2 to 3 hours. You can paint over a layer after just one hour, making them six times faster than Enamel Color paints. The new Aqua Color paints and existing Enamel Color paints (14 ml) can be painted over each other after a certain drying time, but they cannot be mixed together.
