Thanks, I actually used Krylon Flat spray paint for the base and exterior house paint for the details. I would have used an airbrush if I had one, but this way turned out ok. There were quite a bit of colors but I will try to list most of them:
Krylon Automotive Primer (As base)
Krylon Khaki Brown
Krylon Flat Black
Krylon OD Green
The exterior paints that I used with a brush were:
Nutmeg, OD Green and Taupe
There is a sticky in the shotgun forum that has step by step instructions if you wanted to take a look.
