These cans of spray paint are actually great for painting big surfaces. The paint consists of a synthetic acrylic lacquer that cures in a short period of that time period. Each can contains 100ml of paint, that will be enough to totally cover several, 1/24 scale size synthetic model vehicle systems. Tamiya spray paints are not suffering from acrylic or enamel paints. They may be used over a cured spray painted surface.
