These cans of spray paint are actually useful for painting big areas. The paint includes a synthetic acrylic lacquer that treatments in a brief period of times. Each can contains 100ml of paint, which will be sufficient to completely protect 2 or 3, 1/24 scale size plastic model car systems. Tamiya spray paints are not struggling with acrylic or enamel paints. They could be used over a cured spray painted area.
