Paintless dent repair(PDR) is a "scaled kinetic inversion process" of repairing small dents and dings without the need for traditional body work that require fillers and paint. Most PDR work is done by accessing the inside of the body panel to be repaired using specialized tools.
Making PDR even more appealing is that most repairs can be done in a fraction of the time involved with a body shop. Where as a body shop will need your vehicle for a couple of days( at least ), PDR can be done in a morning....anywhere. No major time lost, no need for a rental car, no hassles.
What about cost? PDR is a very inexpensive cost alternative to traditional body shop work. An average door ding can be as much as $350 or more to repair. PDR can fix the same ding starting at $85.
