I made a realistic prop gun using a water gun

Through the Frugal Filmmaker http://filmflap.blogspot.com/ I found this guy KnopTop who has a Quick FX YouTube channel http://www.youtube.com/user/Knoptop. He posted this video for making a plastic gun look like old metal. All you need is black spray paint and metallic spray paint. I think his guns look better than mine, but I still thought it was pretty cool. You can check out the tutorial below:
