Instead all that sweat and hard work produced walls tackier than any bordello. You can get everything from a chain department store or hardware store but you may get nicer metallic paint if you go to a paint store. Target or Wal-Mart is probably cheapest. I quickly learned that antiqued metallics look a heck of a lot nicer on walls. There's just so much space to cover that bright metallics, like the spray paint, make you feel like you're living in a jewelry box.
Antiqued metallics have a burnished finish over all that sparkle and shine.
I know, it's a pain to do. But this paint technique will come out much better over a brown primer than your white walls. Get the corners too or the gold will look weird over the white bits. Rinse out your roller and let it dry too. Metallics have nasty little particles in them that you don't want to breathe so make sure that your room is well-ventilated.
