There are a lot of spray paints on the market. But finding one that will withstand the great outdoors is key to ensure your patio furniture looks great over time.
Keep in mind, even with a great exterior paint, I find touch ups are still required every few years with painted outdoor furniture. BUT, that is a lot more cost effective than replacing the furniture!
