Fender Flares Edge Trim, Fender Flare Rubber Seal for Car and Truck Wheel Wells, Rubber Gasket for Fender Flares Universal, Bonds W/Automotive-Grade Adhesive Tape, T-Style, 30’ Length. Because this fender flare trim seal has a double-edged structure, which is thicker than ordinary rubber trims, if the fender has a 90-degree or acute-angle curved edge, this part will form a wrinkle.
