shjon, I really think the only solution you will be happy with is to remove the mirrors. Not an easy job in of itself. It depends on what kind of mastic the mirrors were put on with. If you will not do that what about the covering wall paper line. They are thicker than regular wall paper, usually have a testure on them and are made to cover problem walls. You may have to go to an off lable paste to get good adhesion on the glass surface. Once the liner is up you can also paint it.
