There are some exceptions that can prevent the repair ability of the dent. Dent repair will work on virtually all panels of your vehicle, with some limitations: 1. if the damage is 1" to 2" from the edge of a door, fender, hood, quarter panel, trunk or roof, dent removal may not work 100%. 2. If there is cracked, fractured, or missing paint at the core of the damage or dent, paintless dent repair may not work 100% 3. Dent repair will not work on pillar panels, rocker panels, or plastic or metal bumpers.
