They are popular for vehicles etc, but has anyone used one on a guitar? I have a vinyl plotter to custom cut decals, but cannot print on vinyl. Lots of sign shops around who have that kind of equipment though. My concern is that urethane or other clear finishes over a large vinyl decal will have adhesion problems. I think many people have done small vinyl decals without a problem, but a large decal may present a challenge. Either with solvents messing with the inks or the heat from the curing causing the vinyl to go soft. My thought was to cover the front, clear coat, then blend in the edges with paint, then clear coat. That way, the edges of the decal would be blended in. Getting vinyl wrapped around the compound curves makes my brain hurt- Anyone done fairly large vinyl with a clear coat?
