Does naybody use an airbrush to wash thier models? What are the pros/cons?

I've never tried that but I do use my airbrush to shade the flat areas of the vehicle, or maybe lighten would be a better word. That way it leaves the grooves and lower parts of the model a darker colour giving it a dirtier, less worn look. Maybe I'll give it atry on an old model to see what happens. :-)

I've applied washes with my air brush, but frankly based on the results, I now steer clear, and strictly use brushes for washes.

I have a two stage airbrush so I can control both airflow and paint/wash flow. It seems everytime I tried to airbrush on a wash I'd get a "splash" look if I was too close, and if I backed off a bit, the wash tended to puddle. Maybe my technique was wrong, I don't know, but it didn't work for me.

However, I've always had success applying washes with various size brushes, so that's how I do it.

As noted above, you could experiment on a couple of older models and see how it goes. If you're successful I'd be interested to hear what you did, and then I'd give a try myself.

Good Luck.

I also use the Airbrush to lighten areas for weathering. I have never used it for wash. I prefer brushes for this.
