My favorite I've done, and one of recent, Kimber Hunter foreend shortened/remolded, painted green, then granite speck applied then clear.
Man I really like that paint! Exactly what is it?
Rustoleum Hunter Green followed by Rustoleum Granite stone texture, practiced with the granite paint before spraying the stock. That's just a couple light swipes with the granite texture paint. Then a pile of clear coats.
