Damage Estimation



When using the sizing coin/magnet, the edges of the dent must be inclusive of the size of the measured circles to be considered that specific size. If the edges of the dent damage exceed the size of the circle on the magnet, then the dent is counted as being the next size up and will not be estimated at the size down or smaller than the actual damage. The affected area is to be determined by the PDR Technician and may include surface area greater than that of the measured indentation.


The following items can be added to an estimate and may incur additional repair costs. Additional items should not be limited to one per panel since each item independently adds to the time and difficulty of the repair. The vehicle and vehicle damage will be inspected to determine access and repair technique/ difficulty. Items that may result in a longer, and/or more difficult repair and may incur additional repair costs include but are not limited to:

Tall Vehicles

Vehicle panels that require a technician to use the assistance of a bench/ladder in order to gain access to perform the repair.

Panels with Laminated Glass

Laminated glass is especially susceptible to damage. Special caution must be taken in order to properly perform a repair on panels containing laminated glass.

Extended Roof

Extra time and advanced techniques/tools can be required to properly repair an extended roof.

Glue Pulling

Glue pulling a dent(s) takes significantly longer to repair than the standard repair method. Some panels require the glue pulling method in order to be repaired properly.

Double Panels/Heavily Braced Panels

This should not be limited to roof rails, doors, and deck lids. This includes areas that are not typically involved in the discussion of double paneled areas. Front of hoods, tops of doors, door area underneath belt molding, quarter panels at front, and deck lids are often heavily braced. A panel is considered a heavily braced / and or a double panel when there is little to no direct access to the damaged area.

High Strength Steel (HSS) and Ultra High Strength Steel (UHSS)

HSS/UHSS have a higher Tensile Strength (MPa), resulting in a more challenging and time consuming repair.


Aluminum has less metal memory, resulting in a more challenging and time consuming repair.

Extra Thin Metal

Extra thin metal results in a more challenging and time consuming repair.

Panels with Sound Deadening

Sound deadening creates a barrier between the technician’s tool and the damage, resulting in a more challenging and time consuming repair.

Poor Access

Extra/tight bracing and lack of factory access holes can create poor access.

Extra Large Panel

Unusually large panels can create leverage problems, access difficulty and require extra time and advanced techniques.

Ribbed Roof

A ribbed roof results in having to repair dents on concave and convex surfaces. Dents that are not on flat surfaces result in a more challenging and time consuming repair.

Deep Dents

Dent depth can be assessed visually by qualified technicians, or measured in mm using a depth gauge.

Over-Sized Dents

See section titled “DETERMINING DENT SIZE”. With minute increases in size of the damage the difficulty of repair increases exponentially. Half dollar, Egg, Tennis ball, Baseball, Softball, and Grapefruit; should all be evaluated as their own respective categories

Sharp Dents

The ratio between dent size and dent depth (determined by the technician), as well as metal type, may result in a sharp dent(s) which require special technique and result in a more challenging and time consuming repair

Multiple connected dents or one or more dents that fall in the affected area of another dent

Stretched dents

Corner or edge dents

Dents on a tight radius, extra stiff curves



Shop supplies, tool tips, glue supplies, solvents, tape, compounds, etc.

Corrosion Protection

Refinishing/sealing undersides of painted panels where soft tipping is not an option

Diagnostic Scanning

With the current liabilities of working on vehicles, diagnostic scans are part of the repair process. Any vehicle with an OBD2 port needs to be scanned for pre-existing codes before work begins, and a post repair diagnostic scan performed to assure that the vehicle has been properly reassembled and that all safety features are communicating properly.

Additionally, should any vehicle features need calibration, the vehicle should be calibrated according to the OEM procedures, which may require the vehicle being sent to a qualified calibration center or dealership.
