For the love of God... Don't use vinyl artwork (self-made, or from twobits.com), or any of the Pac-Man sideart from localarcade.com.
Have patience, and locate a set of stencils. You'll seriously regret using vinyl artwork when the bubbles start showing, or it starts to peel off.
If done properly, the paint will last FAR longer than vinyl will, and can be touched up if needed. As you'll see by many of the Pac restorations here, stencils CAN be found, so as I said - have patience.
