Abstract: A body finish protector for an automobile having a filler neck cap recessed behind the body surface and covered by an access door. The protector comprises a flap of resiliently flexible rubber-like material, one end of which is permanently attached by sheet metal screws or other suitable fastening devices behind the access door. The flap has a first storage position within the recess when the door is closed and a second protective use position when the door is open for providing access to the filler neck cap. When the flap is in the use position, the free end of the flap is folded outwardly from the storage position into overlying relation with a portion of the body exterior surface adjacent the access door. The flap may be installed so that its tendency is to fold out or start folding out when the door is opened. In the use position, the flap protects the area covered by it from marring by the fuel tank filler nozzle and from staining by fuel drippage.
