Paintless Dent Repair PDR Techniques and Methods 2 — Questions and Answers
Question 1: What is the 'reading the dent' process in PDR?
- Looking up the vehicle's repair history
- Analyzing the dent's depth, size, and metal tension before starting (Correct answer)
- Checking manufacturer repair manuals
- Measuring paint thickness with a gauge
Correct answer: Analyzing the dent's depth, size, and metal tension before starting
Reading the dent means thoroughly analyzing the damage including its depth, shape, location of high and low spots, and the tension in the surrounding metal before beginning the repair.
Question 2: Why do PDR technicians work dents from the outside edge toward the center?
- It is easier to access the outside edges first
- Working from edges prevents overstretching the metal while relieving tension gradually (Correct answer)
- The center of a dent is always harder metal
- Edge-first technique requires fewer tools
Correct answer: Working from edges prevents overstretching the metal while relieving tension gradually
Working from the outside edge inward releases tension progressively and prevents the metal from overstretching, which would make the repair more difficult.
Question 3: What does 'feathering' a dent repair mean?
- Applying feather-light glue to a tab
- Gradually reducing pressure as you approach the correct panel height (Correct answer)
- Removing all tools from the work area
- Cleaning the panel with a feather duster
Correct answer: Gradually reducing pressure as you approach the correct panel height
Feathering refers to the technique of gradually reducing pushing pressure as the metal approaches its correct level to avoid overshooting.
Question 4: When repairing a crease dent in PDR, what is the recommended starting point?
- The deepest point of the crease
- One end of the crease, working toward the other end (Correct answer)
- The center of the crease
- Anywhere, order does not matter
Correct answer: One end of the crease, working toward the other end
Crease dents should be repaired starting from one end and working systematically toward the other end to relieve tension progressively along the length.
Question 5: What is 'metal memory' and how does it affect PDR?
- A software tool for tracking repairs
- The tendency of metal to return to its original shape after minor deformation (Correct answer)
- The hardness rating of a car panel
- A type of steel alloy used in modern vehicles
Correct answer: The tendency of metal to return to its original shape after minor deformation
Metal memory is the property of steel that allows it to return toward its original shape; PDR technicians exploit this characteristic to guide the metal back without adding material.
Question 6: Which PDR approach is used for a sharp, deep dent with a defined edge?
- Wide-tip pushing with broad pressure
- Targeted precise pushing along the sharp edge to relieve the fold (Correct answer)
- Glue pulling without rod work
- Sanding the edge smooth
Correct answer: Targeted precise pushing along the sharp edge to relieve the fold
Sharp-edged dents require targeted, precise pushing along the defined edge to carefully relieve the fold in the metal before addressing the main body of the dent.
