PDR Repair Best Practices


These pages serve as a guideline to inform technicians, adjusters, body shops, and the general public about the procedures that may be necessary for proper Paintless Dent Repair (PDR) on a vehicle. While not all listed procedures are required in every situation, they provide valuable insight into those that might be needed and should be carefully considered when requested by the technician performing the repair.


Vehicle Condition:

The estimate should be conducted on a clean vehicle, in an indoor environment, and with the use of professional PDR lighting equipment.

Determining Dent Size:

When using the sizing coin or magnet, the dent must fit entirely within the measured circle for it to be classified as that specific size. If any part of the dent extends beyond the edges of the circle, it should be categorized as the next larger size and not estimated as a smaller one. The affected area is determined by the PDR technician and may include a surface area larger than the visible indentation.

Determining Double Panel And/or Heavily Braced Panels:

The vehicle should first be inspected to assess the level of access difficulty. This evaluation extends beyond commonly considered areas such as roof rails, doors, and deck lids. It also includes less frequently discussed sections like the front of hoods, tops of doors, areas beneath belt moldings, front portions of quarter panels, and deck lids—all of which are often heavily braced. A panel is classified as heavily braced or double-paneled when there is little to no direct access to the damaged area.

Special Cautions:

The details in this guide should be applied with consideration to the unique circumstances of each situation. No two dents, storms, or technicians are exactly the same, and each case should be evaluated individually. Factors such as repair location, storm-specific damage, pre-existing damage in the affected area, and other variables must all be taken into account. Each claim should be assessed on its own merits.

Estimating Explanation:

The necessity of the following procedures should be determined at the discretion of the servicing PDR technician. These steps may be required to access damaged areas before beginning the dent removal process. All R&I (Remove and Install) techniques should be performed in accordance with the manufacturer’s specifications. Please note that the procedures listed below do not include dent removal, panel cleaning or preparation, or marking/highlighting damage for estimating purposes.

The condition of the vehicle’s finish is crucial when evaluating the suitability of Paintless Dent Repair (PDR) as a repair method. Achieving a high-quality PDR outcome requires the paint to be in good condition. Several factors may limit the ability to fully restore the vehicle to its original factory condition, including but not limited to:

  • Removal of wax or paint sealant
  • Reapplication of wax or paint sealant
  • Matte or satin paint finishes
  • Vehicle wraps
  • Stripes, decals, transfers, or overlays
  • Non-factory (aftermarket) paint
  • Cracked, chipped, or deteriorated paint
  • Rock chips
  • Pre-existing damage unrelated to the storm event
  • Damage caused by storm debris, such as falling tree branches or wind-driven objects during high winds

Remove & Install Procedures For Hail Damage Repair Using Pdr Method:


The removal and installation (R&I) of any obstruction necessary to gain visibility, access, or leverage on the backside of the damaged area—on any vehicle—may result in additional charges, as determined by a qualified technician.

Fundamental PDR Procedures:

  • Lifting the vehicle when necessary to improve visibility, access, or to perform the repair
  • Removal and installation (R&I) of any obstructions deemed necessary by the technician to gain access or leverage behind the damaged area

  • The vehicle has a ribbed roof

Paint:

LABOR TIMES:

Labor times should be used to estimate the time required to remove and reinstall vehicle components that obstruct access to damage repair areas. These times may vary based on factors such as the size, depth, and location of the dents, the vehicle’s age and condition, the technician’s experience and equipment, as well as the vehicle’s make and model. Labor rates are typically determined by the regional location.

Because of the wide variety of storm damage and vehicle conditions, labor times for the following items may be added to an estimate. Multiple items per panel may be necessary, as many panels require the removal of several components to gain proper access. The items listed below, which are not exhaustive, may result in additional repair costs and/or removal and installation (R&I) time:

Dents that do not qualify for standard pricing

  • Oversized Dents – Even slight increases in size can significantly raise the complexity of the repair. Dents comparable to a half dollar, egg, tennis ball, baseball, softball, or grapefruit should each be categorized and assessed individually due to their unique repair challenges.
  • Multiple interconnected dents, or any dent located within the impact zone of another, require special consideration.
  • Deep or sharply defined dents
  • Stretched or elongated dents
  • Dents located on corners or edges
  • Dents on tight- radius or highly rigid curves
  • Creased dents
  • Dents on ribbed roof sections
  • Dents on large or extended body panels
