crafty | Paint for metal bottle caps?

If you were going to use some sort of paint and sealer on metal bottle caps that wouldn't chip, which paint would you use? I was thinking both a base coat and some sort of decoration (nothing too complicated). I know they make certain paints just for metals, which I've seen in hardware stores and the like. I thought spray paint might work for the base coat, but I wasn't sure about something I could spread with a brush for detail work. Does anyone have any particular recommendations/suggestions?

Thanks in advance, dreamwidth hive mind!
