I would be very careful. I am not a chemist, but I question if the sprayed side is on the side of the photo, will the chemicals eventually destroy the photo and paper inside if the frame? We are all careful of which archival papers we use when printing, seems that this would also be a consideration as well.
It is the outside of the glass that is sprayed, otherwise there would still be glare, but your comment about chemical reaction is a good thing to remember.
