Hi,

When someone says “when airbrushing the paint you must mist it so that the black undercoat remains visible, repeat this by adding a little white to your base color and mist again”

What does that mean Misting???

The way I understand it is to hold the airbursh back further than normal and put on the as a "mist". You can also lower the air pressure. Recommend you practice on an old model or sheet of plastic. This is based off my reading, as I have not tried it.
