Paintless dent repair (PDR), also known as "paintless dent removal", is a collection of techniques for removing minor dents and dings from the body of a motor vehicle. A wide range of damage can be repaired using PDR; however, usually if there is paint damage, PDR may be unsuitable.
The most common practical use for PDR is the repair of hail damage, door dings, minor body creases, and minor bumper indentations. The techniques can also be applied to help prepare the damaged panel for paint. Such applications are referred to as "push to paint", or "push for paint".
Limiting factors for a successful repair using PDR include the flexibility of the paint, and the amount the metal has been stretched by the damage incurred. Hence, often extremely sharp dents and creases may not be repairable - at least not without painting afterwards.
