I noticed a photo of a pinball machine I have yet to restore while browsing the internet... so I had to see what it was about... It just so happens I have both 'sign shop' equipment and nearly 30 years experience in custom painting.
There is a low tack paint masking vinyl I use for most custom paint themes. Designs are quick and easy to duplicate, but for them to work the surface to be painted has to be prepared properly. If the paint peels off with simple masking tape it would first need to be removed or sanded to make sure all new paint will stick, this will greatly improve its durability.
Primed and painted the first color which is always the lightest color when red is to be used (usually transparent). Paint white, add the stencils, paint red, cover up the red and paint blue then remove all masking.
I do not have the design in the computer, but all I'd have to do is a straight on side photo of the design to convert and clean up.
