Edge Highlighting for slackers

First of all, I love DakkaDakka.  I read posts there quite often, and try to emulate techniques shown.  When I came across this article on edge highlighting, I thought it looked pretty simple.  However, the more I tried it, the more I just could not seem to nail it down. I think it might be the "2 shades lighter" part.  Of course, in my mind, I had already done all the edge highlighting for my army....so  not being able to do it in person was a bummer.

However, today, messing with my airbrush it occured to me that adding white might be a good substitute for this, and since I base all my models white...and I have an airbrush....

I basically used a white primer for the base, then hit these guys with blue(the color I've picked for their helmets, obviously) and before it could dry, I hit it from a distance with the airbrush on full power.  The curves seem to catch the air flow just right and the paint on them is pushed just a bit thinner, giving a look similar to edge highlighting that I am very happy with.

Now...if the airbrush would just paint eyes...
