My mirror is now shiny and black! I like it. My sister-in-law even said it looks like an expensive mirror now - is there a greater compliment? Here are some pics of the journey:
I sanded this bad-boy as much as I could before getting bored. Sanding is a dull activity, and I admit it probably could have done with some more sanding. I also inserted some catalog pages so that I didn't get paint on the glass - this ended up being less than ideal situation.

As you can see, I didn't use a primer, and I do not regret that decision.
3. Three more coats.
