Nino, have you considered for your A list titles (like KISS) getting proper brass stencils made so they have proper ovrrspray ?
I think Timbo had brass or metal ones made a while ago. I would be using these for the six repaints on the queue at the moment. By far the best way of painting a cabinet.
While Gav and I were mucking around with different "tack" stencils, he found the perfect solution where I could spread talcum powder under the stencil which allowed paint to escape under the stencil. The effect was absolutely perfect. Other stencil providers make the common mistake of making perfect lines and circles etc etc - which is not what was done in the factory. The brass stencils were literally placed on the cabinet and sprayed in seconds. Registration issues, overspray and underspray were common. To have a perfect cabinet with perfect lines and geometrically accurate circles is not what I would call a faithful restoration. To me it is like clearcoating a cabinet, or using the incorrect colour.
These machines were painted to attract players, not art critics with protractors and micrometers.
