Maybe I went a little overboard, but this is what happens when you ask a couple of teenage kids how to paint a gun; my daughter had some great ideas, like finding the right netting and stencils, plus it was a reason to take dad to the craft store. My goal was to do a distinct breakup pattern for winter in Minnesota. I taped the necessary things, sprayed it with a warm grey base coat, covered it with netting and did a flat tan overspray, then added flat brown using a 8x11 airbrush stencil bought off amazon. The wife was really impressed, which was a pleasant surprise. As the environment changes (e.g. changes from brown to green) and the paint wears, I can just layer on more paint using the mesh and stencil.
