Abstract: A stone guard to protect the outwardly flared, curved edge of the rear fender of an automobile bordering the wheel opening against stone chipping. The stone guard comprises a body section having a cross-sectional configuration to conform to the contour of the portion of the fender bordering the curved edge, and the forward edge of the body section terminates in a flange which is positioned against the door jamb of the automobile. Extending downwardly from the body section is a lower flange which is adapted to be attached to the rocker panel of the automobile. Both the upper and rear edges of the body section are tapered in cross section and are disposed adjacent the curved edge of the fender bordering the wheel opening. Adhesive strips serve to secure the body section to the fender of the automobile.
