KevinY- I can understand your hesitance in airbrushing bodies. CobraColors is awesome stuff, but it does work best if you've had some expeince with airbrushing. Sooner or later, it will of course be time to try iairbrushing a body, and when that will be is entirely up to you. But before trying CobraColors, at least thoroughly read through all of the tutorials Leon has posted on his CobraColors site.
