These cans of spray paint are actually useful for painting large areas. The paint is made of a synthetic acrylic lacquer that cures in a short span of times. Each can contains 100ml of paint, that's sufficient to completely protect 2 or 3, 1/24 scale size synthetic model car numbers. Tamiya spray paints aren't suffering from acrylic or enamel paints. They might be used over a cured spray painted surface.
