Revell Aqua Color paints come in new 18 ml containers and are ideal for use. The paints 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 available that can be mixed together. The paint is completely dry after 2 to 3 hours, and it is possible to paint over a color after just one hour, making it six times faster than enamel paints. The new colors and the existing enamel paints (14 ml) can be easily applied on top of each other after the drying time, but they should not be mixed together.
