You do know that Defender is a stencilled game right? So it was just painted with a stencil and a spray can.
New stencils are available if you want to go that route.
If stencils are available, I would like to see where. I have looked at many sites, and haven't found any stencil sets yet. Some of the sites that I found links to that were supposed to have stencil sets for Defender, didn't.
Anyway, the original art was a total loss. It was under several coats of paint, and the cabinet was pretty beat up. At the time I wasn't planning on using it. The more I restored the cab, though, the more it was making sense to return it to original Defender glory. Had I decided to do it from the start, I would have traced the art.
Again, if anyone has links to a site that carries Defender stencils, please contact me.
