Repairing cracks is simple and quick with masking tape or duct tap. For minor cracks, such as stress cracks that are caused due to differences in temperature one strip of tape covering both sides of the window should be enough. For deeper cracks, like those caused by impact, it's recommended that the tape is extended across the entire length of the crack to ensure it can keep the glass in place.
