The decals (or whatever you'd call the control panel stick-on labels) on my two original Duo-Therm overhead A/C units are getting pretty tired and wrinkly. The A/C units still work just fine, so I'd hate to replace them... but I would like to make 'em look new again, which would require replacement decals / labels (the ones that surround the two knobs). Has anyone ever seen these out there anywhere? I've had no luck with 'net searches.
