It's been many years now but someone brought in a oval convex glass mounted print. I'm certain it was the most expensive way back then. It was also welded into the glass. Our idea was to just make a copy photo, but the convex glass picked up all the reflections from 180 degrees around. We finally resorted to having an airbrush artist work on all those reflections. I still wouldn't have any better recommendations, except PhotoShop.
If you ever have to do that again put lights on each side at 45 degrees with a polarizing filter on each oriented the same way and then put a polarizing filter on your camera and dial away most if not all the reflections. With this setup you can control reflections on all sorts of surfaces including metal.
