I'm pretty sure that framing a metallic photo with glass, ruins the effect. All the good ones I've seen are mounted on top of a stiff backer and displayed with no glass. Or, a framer will put a frame around the metallic frame but with no glass. You'd have to ask an expert if there is some kind of spray that can be applied without affecting the metallic finish.
Having been a professional framer for 20+ yrs. I do again suggest museum glass. The crystal clear nature will only ENHANCE the metallic effect. With the metallic paper, spraying or coating it will have a negative outcome. I AM SPEAKING FROM EXPERIENCE WITH AN EXPERT OPINION. Have a nice day.
