Me too. As I get through my restore, I'll be
updating this thread which will (soon, tomorrow or Wednesday I think) have details about my control panel restoration and my new sides. Anyway, that thread has information about ordering custom vinyl, but here's the upshot:
custom vinyl sides runs about $170.
I actually found a pretty economical way to get the sides laminated (wood laminate like the 6-slot units), so that's what I'll be doing. In all the cabs I've seen with hard lam, they've had spray painted / air brushed logos.
Buying the reproduction vinyl and using that as a stencil (cutting out the logos then airbrushing them to the cab) occured to me as well, but any time you mess up a cut, it's 15-35 bucks. Versus contact paper / projection, where it'd cost about $3.
I might actually buy the reproduction, scan it, print it on transparency, project it, and then use the reproduction to gauge size... THEN trace contact paper, then cut it out, then use that as a template to paint.
Obviously, I'm overthinking this bit of my project, but I really want it to look good.
