This is a great color and shade, it is very consistent and overlaps well. Its a great substitute for other grays on WWII planes and ships.

As with all Tamiya acrylics, thin between 1:1 and 2:1 paint to thinner for airbrushing. I personally thin about 65% thinner. 15-18 psi. Brush paint in one direction only and avoid over brushing until first coat is cured (not just dry to the touch)

Tamiya makes the hobby paint on the planet. Its so easy to work with. The coverage is awesome. At first, coming from Testors, I was hesitant because Testors is so thin and barely covers. Once I used it, it was a game changer. I will be switching all my paints to Tamiya.
