Can I Paint My Steel Garage Door?

Of course, you can, but you don’t have to. As long as the enamel finish is intact, you don’t really need to add another coating; if you do choose to paint then you’ll have clean the garage door regularly to maintain the color and prevent rust. However, some people get tired of having their door remain the same color all the time, and if you get new siding or roofing, you might want to repaint the steel door to match. In addition, you should repaint if the door has any bare metal showing so that you can prevent rust.
