What I have done to mine is use auto primer in gray, brown, OD green, and black. All flat colors and then spray with flat clear laquer to seal. The foliage patterns came from using the plastic leaves as overlays from the craft center area at Wal-Mart. I iron them flat between towels and they lay nice and flat and for the curves I use double sided tape to hold them in place. Layering comes from adding more leaves as you add more colors. Use a good quality primer like Rustoleum. Wipe the stock after painting the clear coat on and the finish actually is somewhat rough for a good no-slip grip.
