Paintless Dent Repair (PDR) is the technique of removing dent and dings from your automobile by massaging the damaged metal with specialized tools back to its original condition without fillers and painting. This maintains the original factory paint, thereby eliminating color mismatch issues created by traditional body shop repairs and generally can be completed at your home or workplace within an hour at a fraction of the cost.DentTech has been providing many of the largest body shops and auto dealerships this service since 1998 in the San Francisco Bay Area.
