This is the mirror from the dresser set I did for my daughter. Ignore the junk in the background, except that wonderful fur chair.
Anyway, I am in the process of painting it Gold. I love the Martha Stewart Metallic Paints, that you can get at Home Depot. Using Vintage Gold. I will leave the gold that is on the mirror and just lightly put the vintage gold over it. No prep needed, as that metallic paint attaches pretty good, and I don't mind a few nicks and scratches.
Hope to have it done this week and to post a full picture.
