I have a chandelier that is brass in appearance. It isn't anything fancy... just one of those lower end chandeliers that came with the house.
I saw a TV show a few months back (can't remember which one) that painted over one of these cheap chandeliers with black spray paint. However, (now this is the part I can't remember) they had a tiny bit of brass showing though on the edges. I can't remember if they painted it in a two step process... one with a bronze color and then a second light coat of black...
I don't know if anyone else saw this show I'm thinking about.
In general I would appreciate any suggestions on preparation and technique. My end goal is to have it look like an dark weathered bronze (almost black) finish.
