I was looking at the paint I had and noticed I had a can of red, that I used once and loved, but hadn't touched since. I also had a couple guns that had base coats on them, but didn't really have any plans. I doodled on a piece of paper trying to figure out how to make a good looking white and red gun, but every design ended up looking like a candy cane.
Out of no where I remembered some stencils that had come with one of the guns I bought recently. I grabbed one at random, it was the nerf logo. I went back outside, with the white gun, red paint and stencil. I didn't paint the gun at first, just stood there, worried it would look terrible after I painted it. I decided whatever, and stenciled the word "NERF" on the gun over and over. And ended up with this.
The gun, much to my surprise, turned out great.
