Which light source is most commonly preferred for reading dents in modern PDR?
Answer: An adjustable LED PDR light or line light
Adjustable LED line lights provide consistent, portable reflections in any environment.
What is the glue-pull method in PDR primarily used for?
Answer: Dents with no rear access
Glue pulling lifts dents from the outside when there is no access behind the panel.
What does 'gloss' of the paint surface reveal during dent assessment?
Answer: Areas of stress or paint stretching that appear as dull spots indicating possible cracking risk
Areas where paint has been stressed appear duller than surrounding surfaces, indicating overstretched paint that may crack during PDR if not handled carefully.
Why do PDR technicians often choose to work as independent contractors rather than shop employees?
Answer: Independence allows them to set their own rates, choose clients, and keep a higher percentage of earnings
Independent contractor status gives PDR technicians flexibility in pricing, client selection, and schedule, and typically results in higher earnings since they retain most of each job's revenue.
What does a 'sharp' dent (as opposed to a 'soft' dent) indicate about repairability?
Answer: Sharp dents have a defined crease that makes repair more challenging and time-consuming
Sharp dents have a defined crease or fold in the metal that requires more careful, targeted work compared to soft round dents, making them more challenging and time-consuming to repair.
What can cause small dents in a car?
Answer: Door Dings
Door dings are a very common cause of small dents in cars, typically occurring when another car door swings open and hits the side of a parked vehicle. These types of minor, shallow dents are often ideal candidates for Paintless Dent Repair (PDR). They usually don't involve paint damage and are small enough for technicians to effectively push out the indentation.
What is a 'bullseye' dent and what PDR challenge does it present?
Answer: A round dent with radiating stress lines that indicate the paint may be at risk
A bullseye dent has a circular shape with radiating stress lines, indicating the impact stretched the paint and metal significantly, raising the risk of paint cracking during repair.
When preparing a vehicle with widespread hail damage for PDR, which panel area is typically addressed first?
Answer: The roof panel
The roof typically receives the highest concentration of hail impacts and is addressed first to establish a systematic workflow pattern across the vehicle.
What feature distinguishes a 'whale tail' tool from a standard PDR rod?
Answer: A wide, flat blade for broad leverage on large panels
The whale tail's wide flat end spreads force across large, accessible panels like doors and quarter panels.
What is the purpose of paintless dent repair?
Answer: To fix dents in trucks, SUV’s, Jeeps, Crossovers, Vans, Mini Vans, Panel Vans, and more
Paintless Dent Repair (PDR) is a versatile technique designed to remove minor dents and dings from a wide range of vehicle types without requiring repainting. Its purpose is to restore the vehicle's body panels by carefully manipulating the metal back into its original form. This preserves the original factory finish across various models, from cars to larger utility vehicles.
What is the role of before-and-after photography in a PDR business?
Answer: Before-and-after photos document the repair for liability protection, marketing, and customer satisfaction records
Before-and-after photographs document the pre-repair damage and final result, protecting the technician from false damage claims, supporting marketing efforts, and maintaining quality records.
How does high-strength steel (HSS) differ from mild steel in PDR applications?
Answer: HSS is more rigid, resists deformation, and is more prone to work hardening, making PDR more difficult
High-strength steel is engineered to resist deformation, which means it also resists PDR manipulation and work-hardens faster than mild steel, requiring specialized techniques.
What is 'oil canning' in the context of PDR?
Answer: An unstable area that flexes in and out under pressure
Oil canning is a loose, springy spot that pops in and out and must be stabilized.
How does PDR differ from traditional auto body repair for dents?
Answer: PDR preserves the original factory paint by working the metal back from behind
PDR preserves the vehicle's original factory paint finish by massaging the metal back into shape from behind the panel, eliminating the need for filler or repainting.
What is a 'tension ring' in dent assessment?
Answer: The area of raised metal surrounding a dent caused by impact tension
A tension ring is the ridge of raised metal that surrounds the low point of a dent, formed when the impact pushed metal inward and displaced it outward.
What is the 'shadow test' used for in PDR quality inspection?
Answer: Positioning a single directional light to cast shadows across the repaired area, revealing any remaining high or low spots by the shadows they create
The shadow test uses a single directional light source positioned to cast revealing shadows across the repair area; any remaining surface irregularity casts a visible shadow that confirms the repair needs more work.
Why is thoroughly documenting pre-existing damage critically important before beginning vehicle preparation for PDR?
Answer: To protect the technician and shop from liability for pre-existing damage
Documenting pre-existing damage before starting work protects the technician and shop from being held responsible for scratches, prior dents, or other damage that was already present.
What is the value of PDR training that includes working on hail-damaged vehicles?
Answer: Hail events involve high dent counts and strict time pressure, training technicians to work efficiently and consistently across many similar dents on the same vehicle
Hail repair training develops the speed, consistency, and mental endurance needed to work through high dent counts efficiently — skills that translate directly to productivity in normal repair work too.
How should a PDR tech assess a dent located near a body line?
Answer: Body lines change how metal tension is distributed, making dents near them harder to repair
Body lines create concentrated metal tension that changes how the panel responds to pushing, making dents near or on a body line significantly more difficult to repair correctly.
What does the 'crease tool' in a PDR set address specifically?
Answer: Sharp line dents and creases needing concentrated pressure
Crease tools apply focused leverage along sharp line dents to work them out gradually.
