Bought a fixer upper for rental, the bathroom mirrors are good except for the bottom 2 inches where the silver is gone and they are dark in the back. There is not enough room to frame the mirrors . Is there some type of a trim tape that would look decorative, hold up to water splashing on it and could be run across the bottom edge, or a thin cheap mirror border. Being a rental I don't want to put much money into this. I heard about painting it. What type of paint would I use? Thank you for your time and help.
