So, I bought a mirror that was on the clearance rack a few days ago. It is small and cute, and when I saw it, I thought, 'Wow, that would make a great scrying mirror'. I took a picture of the box rather than deal with reflections and flashes and such --->

Nice, eh? It does have a small scratch in the center (which I am working on buffing out), but I am a bit stuck on what to do now. Should I try and paint it black? Leave it silver and just use it in the dark? If I paint it, can I seal it strongly enough that it won't get scratched later on? All of the instructions I found on google have to do with using a picture frame and black paint. Those aren't really going to help me.
Any ideas?
