****, I wish my avatar was my business card. Ace Hardware is where I work, Paint department specifically.
i looked at the durakote, its great if you're painting more than one firearm. if you're painting one, Kyrlon Camo with Fusion Technology. Just one thing to add, wait after you paint it, at least a week before any rough handling.
the guy at Operational Tactical has this weapons painting guide, he used Krylon spray paint. http://www.optactical.com/weaponpainting.html
