Paintless Dent Repair (PDR) does have its limitations when it comes to the size of dents it can successfully mend. It is highly effective for small to medium-sized dents, but may struggle with extremely large dents or those with pronounced creases. PDR is best utilized on dents where the paint remains intact and the metal hasn’t been excessively distorted. However, the specific boundaries of what PDR can achieve can vary, often hinging on the proficiency and expertise of the technician conducting the repair.
