That's the way Chris! Whether it's an airbrush, spray can or full sized spray gun, the technique is the same, just like spraying a car. Start spraying before hitting the 'target', and follow through off the target. Always keep your wrist locked so that the 'brush/can is parrallel to the area being sprayed, and not twisting off to one side at an angle, in order to ensure an even coverage, without gaps, thin areas or build-up. With a spray can in particular, test-spray first, (onto card, a wall, the dog, anything but the model!)at a distance of at least 8 inches, to see how heavy the spray is; you might need to move the can further away from the work, to avoid too heavy a spray pattern or heavy paint deposit.
