These cans of spray paint are actually helpful for painting large areas. The paint includes a synthetic acrylic lacquer that cures in a short span of that time period. Each can contains 100ml of paint, that will be sufficient to totally protect 2 or 3, 1/24 scale sized plastic model automobile systems. Tamiya spray paints are not struggling with acrylic or enamel paints. They may be used over a cured spray painted area.
