Abstract: A cover for use to cover the windshield and the forward roof portion of an automobile where a moonroof may be installed is disclosed which cover is retained by being clamped between the window frames of the front doors and the front door frames of the automobile. The cover is of one-piece construction, and may easily be installed by a single person to snugly cover the entire windshield and front portion of the roof of a car, protecting it both from sun and from inclement weather. The cover has anti-theft provisions built therein to effectively secure the cover once installed against removal by wind or theft.
