OK, I realize that airbrushes produce a really great finish,
but I've got a problem with some of the stuff I've seen.

When I see models with say, RAF bi-color patterns or modern
American tri-color patterns, I see alot of this feather edge
freehand stuff, where one color kind of feathers off into another.

However, on the actual  aircraft and vehicles I have seen, the
lines of demarcation between colors seem pretty distinct and should be
more so on the smaller scale model.  So what's going on here?
Is this a case of the tool driving the modeller?

Specifically, I'm working on an A-10 now with a three color
camouflage pattern (dark green, medium green, and dark grey).
When I look at the plans, what I see represented are distinct
patches of color, but when I look at the box, I see this indistinct
feathery stuff.  My inclination is to mask and use the airbrush or
use a brush.

Any opinions or advice on this?
