# How to Paint Fiberglass Porch Beams
Over time, fiberglass porch beams can become faded by the sun. Fiberglass is painted with gel coat, which is a paint and a protective layer that is basically fiberglass resin pigmented with color. Gel coat has additives that protect against ultraviolet rays for outside applications. Repainting fiberglass beams is relatively easy, and it's much cheaper to do it yourself rather than hire a professional. Gel coat supplies can be found at marine supply stores.
