Videos: How To: Paint a Hydrant
Here are step-by-step instructions on how to paint a fire hydrant. (who knew you aren't suppose to paint the top lug because they are color-coded so the firefighters know what type of water pressure it connects to?!)
Remember if you are painting fire hydrants, the paint is oil-based, so wear clothes you don't mind getting paint on that's going to be on there forever. It also takes time to dry, so if it's on your hands or clothes, don't touch anything you don't want to be yellow.
