CAADE Vehicle Damage Assessment 5 — Questions and Answers
Question 1: When a bonded (adhesive-attached) exterior panel such as a rear quarter is replaced on a steel unibody, which joining method replicates OEM construction?
- Fusion MIG welding along the entire seam
- Panel bonding adhesive combined with plug welds at structural locations (Correct answer)
- Rivets and seam sealer only
- Spot welds spaced every 10 mm
Correct answer: Panel bonding adhesive combined with plug welds at structural locations
OEM bonded panels use structural adhesive for large surface areas and plug welds at designated structural points to match factory strength and corrosion resistance.
Question 2: A vehicle struck in the front has a bent radiator support but the frame rails appear undamaged. Which measurement best confirms whether the engine cradle is still in its correct position?
- Hood gap uniformity
- Datum plane measurements at the cradle mount holes compared to factory specifications (Correct answer)
- Tire contact patch alignment
- Engine oil level inspection
Correct answer: Datum plane measurements at the cradle mount holes compared to factory specifications
Engine cradle position is verified by measuring its mounting points against vehicle-specific datum plane data, ensuring drivetrain alignment and subframe geometry are correct.
Question 3: Under ICAR repair procedures, why must weld-through primer be applied before spot welding replacement panels?
- It increases the electrical conductivity of the weld
- It prevents corrosion in the weld zone where protective coatings are burned away (Correct answer)
- It replaces the need for seam sealer after welding
- It lowers the temperature required to form a nugget
Correct answer: It prevents corrosion in the weld zone where protective coatings are burned away
The heat of welding destroys surrounding corrosion protection; weld-through primer provides a sacrificial zinc-based coating to protect the bare metal in the weld flange area.
Question 4: When estimating paint refinish time for a bumper cover that has been removed for repair, which step should NOT be included in the R&I labor?
- Disconnecting park sensors
- Spraying the complete bumper cover with color and clear (Correct answer)
- Removing the fascia from the vehicle
- Releasing the retaining clips
Correct answer: Spraying the complete bumper cover with color and clear
Refinish (paint) labor is a separate line item from R&I (remove and install); applying color and clear is charged under refinish, not removal labor.
Question 5: An appraiser discovers that a vehicle has a salvage title prior to the current loss. How does this affect the appraisal?
- It has no effect if the damage is unrelated to the prior salvage event
- It reduces the ACV because salvage-titled vehicles carry a stigma discount in the market (Correct answer)
- It automatically makes the current loss a total loss
- It increases the repair cost estimate by a fixed percentage
Correct answer: It reduces the ACV because salvage-titled vehicles carry a stigma discount in the market
The resale market applies a stigma (brand) discount to salvage-titled vehicles, lowering their ACV compared to clean-titled equivalents regardless of repair quality.
Question 6: Which of the following best describes a 'short pay' situation in auto damage appraisal?
- The vehicle owner pays the deductible in installments
- An insurer pays less than the appraised amount without proper justification or negotiation (Correct answer)
- A shop completes repairs for below the agreed estimate
- A supplement is approved before teardown is complete
Correct answer: An insurer pays less than the appraised amount without proper justification or negotiation
Short pay occurs when an insurer issues payment below the documented appraisal amount without a valid, negotiated reason, which may trigger appraisal clause or legal remedies.
Question 7: When performing a damage assessment on a carbon fiber reinforced polymer (CFRP) component, which inspection technique is used to detect subsurface delamination not visible to the naked eye?
- Dye penetrant testing
- Coin tap test or ultrasonic inspection (Correct answer)
- Magnetic flux leakage
- X-ray fluorescence spectroscopy
Correct answer: Coin tap test or ultrasonic inspection
A coin tap test identifies hollow sounds indicating delamination in CFRP, and ultrasonic equipment provides more precise subsurface defect mapping in composite panels.
