This is awesome work Nino, Thank you for sharing your process and details.
This has inspired me to look at an airbrush for future playfield work.
I just bought a plotter for making cabinet stencils and I can see it being handy for making playfield lettering stencils also.
Everytime I read one of your restoration posts I seem to learn something which is brilliant!
Cheers: Brettski... :)
