A protective cover includes a sleeve which overlies the entirety of the inside and outside of a vehicle window and has a peripheral seal which seals against the frame for the window which is integral with the vehicle body. A sock-like sleeve encloses the vehicle side mirror and a large protective portion overlies the painted door structure below the window. Fore and aft straps have fasteners on their ends which allow fastening to fastener halves mounted inside the front and rear wheel wells of the vehicle.
