If you have a air compressor you can pick up a spray gun pretty cheap. I suggest a gravity feed type, there much easier to use. Then you can use any paint you want, spray base coat-clear coat paints, and adjust the spray pattern. Here's a tank i did. I used House Of Colors Pitch Black as the base coat, then added some metallic flake to the clear coat. Wish I hadn't added the flake, it looked much better plain black. I love the shine though, you can see a reflection of me taking the pic.
