hey wbill76,
You'd be better off practice spraying on a piece of styrene thats been painted. Airbrushing paint on paper will have a different finish than on primered or painted plastic. While a very good test bed, it has different surface qualities than plastic.
I keep a sheet of styrene handy and check my spray pattern on it. When it gets too difficult to see what I'm painting I just hit it with another coat of primer and it gives me a new blank canvas. Too much build up can be cleaned off with some alchohol or just a new primered piece of styrene.
Nice piece of model building there. I built Tamiya version of this and I've been looking into building dragon's version. Hope its as good as yours.
BTW, I'm a big fan of the aztek and have used it for some pretty great paint jobs.
