I found my toy gun at a thrift store for a dollar. Technically it's a little short, but it was very close for a very cheap price. After you have a piece, tape off your first section for painting.
I started by taping off the bottom so I could paint over the green and get a nice silvery grey color.
Before actually spraying it, I scratched in the writing on the barrel. I did this with the hope that the letting would show through post painting. It nearly worked.
Post painting, I determined that it was just too shiny and silvery, so I added a light coat of black.
There! Much better! Now the hard part of letting it dry. Seriously, just let it dry.
Now unwrap the bottom part and carve the pentagram into the handle and tape up the already painted part. I taped up as much as I needed and then covered the rest with newspaper.
Paint the handle and again, let it dry. A sunny day is best.
Looks pretty good! Some of the etching might need some touching up.
A little extra scratching and it looks pretty nice.
Last steps are the designs. I looked up a good reference shot from the show for the designs and the gold stripes. I started taping off for the lines, but it started to take paint off, so the second line I did by hand. It's not as straight but still okay.
And it's done! (Add a little orange tip if you're going out!) Hooray!
