CAADE Damage Analysis and Inspection 3 — Questions and Answers
Question 1: A vehicle has been repaired and repainted, but the appraiser notices the new paint has a slightly different texture (orange peel) compared to adjacent panels. This most likely indicates:
- Factory panel replacement
- A previous collision repair using non-OEM refinishing standards (Correct answer)
- Normal paint aging differences
- Delamination of the clear coat
Correct answer: A previous collision repair using non-OEM refinishing standards
Texture differences between adjacent panels typically indicate a refinish repair, as factory paint application produces consistent orange peel across the entire vehicle.
Question 2: Which condition describes inward buckling of the firewall or front floor pan caused by a severe frontal collision?
- Sway
- Kickup damage
- Mash (Correct answer)
- Twist
Correct answer: Mash
Mash damage refers to a shortening or crushing of the front structure, often accompanied by firewall intrusion and floor pan buckling.
Question 3: An appraiser using a UV light source during inspection is primarily looking for:
- Frame cracks
- Repainted areas or body filler repairs (Correct answer)
- Rust perforation
- Fluid leaks under fluorescent dye
Correct answer: Repainted areas or body filler repairs
UV light can reveal overspray, repainted panels, and body filler repairs that are not visible under normal lighting conditions.
Question 4: When a vehicle sustains a rear-end collision, which structural component is most critical to inspect for hidden damage in a unibody design?
- Front subframe mounts
- Rear frame rails and spare tire well (Correct answer)
- Firewall reinforcement
- Hood hinges
Correct answer: Rear frame rails and spare tire well
The rear frame rails and spare tire well absorb and transfer crash energy in a unibody vehicle, making them prone to hidden crush and buckling.
Question 5: A vehicle's door opens and closes properly but shows uneven gaps at the top versus the bottom of the door aperture. This condition most likely indicates:
- A worn door hinge only
- Hinge pillar or rocker panel distortion (Correct answer)
- An incorrect door installed
- Normal body flex
Correct answer: Hinge pillar or rocker panel distortion
Parallelogram-shaped door apertures (tapered gaps top vs. bottom) indicate distortion in the surrounding structure, such as the hinge pillar or rocker.
Question 6: During inspection, an appraiser discovers undercoating has been freshly applied to only the rear underbody. This is a red flag indicating:
- Recent factory rustproofing
- Possible rear collision repair concealing structural work (Correct answer)
- Routine maintenance undercoating
- Dealer preparation prior to sale
Correct answer: Possible rear collision repair concealing structural work
Selective fresh undercoating in only one area is a classic technique used to conceal structural repairs, weld seams, or corrosion from prior damage.
Question 7: Which measurement on a vehicle's body indicates 'sway' damage condition?
- Diagonal measurements are unequal front to rear
- Left-to-right width measurements are unequal across the front or rear (Correct answer)
- Vertical height measurements differ side to side
- Wheelbase measurements are shorter than specification
Correct answer: Left-to-right width measurements are unequal across the front or rear
Sway damage is identified when the front or rear of the vehicle has shifted laterally, causing unequal left-to-right width measurements.
