Funtronics has the right stuff,
http://www.fun-tronicsllc.com/index.php?crn=258&rn=635&action=show_detailBut if your trying to save money and you spray paint things like I do... I tend to go a little heavier with paint and sand out if there is a hair or whatever and touch up the imperfections. Im a little OCD, thus I have gone thru 3 cans just doing a old 1950's tool box that was my Great grandpa's. Still not quite done. But Rustoleum makes some nice Red colors that a made for metal use, and at 5 bucks a can you can get a few verse the money for one of the real stuff. I thnk it says primer and paint in one but I would go ahead and primer and light sand it before paint application. If you don't have a sand blaster or a buddy with one go with the fly wheel idea or some good old fashion sandpaper and a block. Just make sure you take that fine grit back over everything and layer the paint and don't get into to big of a hurry... Oh and good ventalation. I liked it with the old sticker on there had a nice look, but get a good red paint and Coca Cola logo on there and it will pop. Im a Sooner fan so everything looks better in shades of red and white...
