Quoted from sethbenjamin:

I have been intending to get on this for awhile…I’ve got one SF with an apron, one without. I can scan the original and make decals. I’ve gotten good results using vinyl decal paper with my Epson photo printer.
The SF apron has a pretty elaborate design (it’s remarkable just how much art they packed into these machines, really.) And yeah, the narrow parts around the border make this one particularly fussy to reproduce, which is why I’m thinking adhesive decal paper is the way to go. The stuff I found is still really thin, but takes color nicely. Last apron I worked on I sprayed a few layers of Rustoleum clear over the decals, which worked very well. I’m not sure if there would be an issue doing this with auto paints and clear coat, but enamel paint and clear looks quite decent, main drawback is just the layering of paint and annoyingly long cure time.
See pics. I’ve only done this one apron, and it’s comparatively simple, but at least gives a bit of “proof of concept.” I’ve made other more colorful decals and they have really good saturation. [quoted image][quoted image][quoted image][quoted image][quoted image]
