If the cracks aren't caused by mechanical damage, or a jarring impact to the window, they can be repaired with epoxy and some elbow grease. Begin by cleaning over the area that is cracked with a wet cotton rag. Then, apply epoxy to the crack, according to the instructions of the manufacturer. Let the epoxy completely dry before applying paint and sanding to the repaired area.
