If Richard Serra is your favorite artist and the word "vintage" sends you racing to the nearest junkyard or flea market, plain, unadulterated metal is not on your decor list. Waiting around for nature to take its course on exposed tin, steel and iron is time wasted dreaming about a rich rusty finish. Speed up the process with household chemicals and coat your favorite metal wind chimes, punched-tin lantern, stripped wrought-iron candlestick, or steel picture frame with an "aged" orange-brown patina. Degrease the stripped metal with a commercial degreaser to remove grime, dirt or remnants of finish that will prevent the chemical reaction that causes rust. Wear protective goggles and gloves every time you handle chemicals during the rust patina process. Do not handle a degreased piece of metal with your bare hands, to avoid any skin oil residue, which repels the rusting solution.
