Took an old Salvation Army store mailbox and gave it a faux rust treatment! LoVe How it turned out! I just used a sponge brush to paint on a few coats of matte brown acrylic paint, pulling at it so the paint had that raised, textured look (as in, don't brush it on). Then I sponged on some raw sienna (orangey color), and a little bit of gray. Played with it till I got the look I wanted. LOVE the vintage look!
