I have done a couple of rifles in camo Duracoat. Pick some type of pattern, pick the colors (preferably to match the terrain you are in). Figure out what you will use as a stencil or something to create the pattern. Start with the lightest color first. Coat the whole weapon (or at least the majority) with the light color. Apply first stencil to block out where you want the first color to show through. Apply second color over entire weapon. Apply second stencil. Apply third color... and so on.
The first camo pattern I did was woodland. I used woodland brown, woodland tan, woodland green, and matt black in duracoat. I initialy used thier provided stencils, then switched to cutting out my own random stencils with an exacto blade out of thier material. It turned out really well and matched my woodland BDU's quite well.
The second pattern I did, was using the same colors, but a different pattern. This time I was going for a snake skin type pattern. I used tan as the base. I then used a laundry bag for a mesh pattern by holding it over the weapon by hand, and spraying the other colors over the mesh. I didn't use any stencils other than this mesh. I just held it over and sprayed green, brown and black over the tan and mesh in different spots. Not much black, more green and brown. I think it turned out pretty well, however a little lighter colored than I would like. If I did it over, I would put down some green or brown splotches all over the tan before puting down the mesh and spraying over that.
