Once you remove the plastic inner fender splash shield on the XJ, you've got a clear shot to the door hinges and front edge of the front door from the wheel opening. We chopped a pool noodle to length and jammed it up between the inner and outer fender to keep mud and debris from fouling the hinges. We later painted it semi-gloss black to make it blend in better. Like any fiberglass fender product we've put on a Jeep, some massaging was needed to make these flares fit correctly. We used a 40-grit flapper disc on our angle grinder to get the job done.
