I use this airbrush paint whenever I want something lighter than Steel or Gunmetal, but darker than dull aluminum. Think of any flat/dull aluminum color, and this one is just one shade darker. An upside is that this sprays fine over any primer I have tried, it does NOT need the gloss black base to work. Alclad paints are expensive, however they are worth it, the metal finishes are second to none. A couple drops in your airbrush is enough to do whole parts, I have not needed a second bottle.
