Fly-in-hi, glad to see the detail shot. The dark grey wash is a nice subtle touch that doesn't come off as so heavy handed. It seems to help the eye keep moving around and not get stuck on just one spot. =] I've been considering colors other than black myself lately.
I actually bought this wash in a set of 3 colors that are supposed to be used on modern jets with light grey, medium grey and dark grey paints. This wash was the darkest of the three. I'll probably try the medium shade on the F-22 that I'm working on.
Although, I think these washes could be used on other colors like SEA schemes and such.
