Abstract: A method of attachment of an external vehicle cover which includes means for discouraging theft of the cover is disclosed. The cover is made from a flexible material tailored to the section of the vehicle to be protected. It includes regions that can be clamped between articulating parts of the vehicle, such as a door and its frame. The end of the clamped region of the cover which is interior to the vehicle terminates in a thickened bead which prevents it from being pulled from the interior of the vehicle between the clamping surfaces of the vehicle. Thus the cover can only be removed from the vehicle by opening the door or cutting the ends therefrom. Removal by cutting renders the cover unusable and thus useless to a thief.
