Me too!!!
Allow me a moment to wax poetic about my reasons for painting the body first, and also why I try to get most of the parts assembled and glued before primering and painting.
Most of us would think it is a mistake to do it this way, I know I thought so for many years, but with particular builds--this one is no exception--my fear always takes me back to my early days of building models when I would more likely than not goop up the glue, mess up a perfectly painted part painting it and THEN gluing it. A few years ago I had no idea how to use an airbrush (and I am not claiming I know how to use one now!) but now the aparatus has become more familar to me. In fact, I have lost every single iota of fear I had for it, which really helps. You know the saying, practice makes perfect!
Also, the fact that I was finally able to afford an Iwata Micron airbrush, and it's allowed me to really come in close and spray in tight spaces . . . which suddenly made it easier to assemble the parts first, doing so cleanley with Tamiya thin liquid cement, and then creative a smooth, unbroken canvas upon which to airbrush my paint . . .
None of the detail is really sacrificed much . . . of course, this would not work for an ultra shiney paint job!!!

But it IS a perfect technique for extreme-weatherd vehicles. And I should add that although this might be new for car builders, it certainly is not for our friendly folk over in the military part of the hobby. They've been doing it and doing it well for years!!!
Oh, and one more word about helping you lose the fear of the airbrush. When I first got my Eclipse--the first Iwata I was really able to afford--I carried mine to work, kept it in the car while I drove and I would practice and the pushing-down-pulling-back motion of the trigger. You do this enough and your hand and finger gets used to the machine!
