Vehicle Damage Identification Flashcards

Which term describes damage that is visible only after disassembly of a component or panel?

Answer: Hidden damage

Hidden damage is concealed behind or beneath components and is only revealed during teardown or disassembly.

A vehicle's unibody frame shows a 'diamond' distortion. What does this indicate?

Answer: A twisting force applied diagonally across the structure

Diamond distortion results from a diagonal force that causes the body to twist so that one corner is pushed forward or backward relative to the opposite corner.

When appraising hail damage, which tool is most appropriate for measuring individual dent depth?

Answer: Depth gauge (PDR dent gauge)

A PDR dent depth gauge measures the depth of individual hail dents accurately, which is critical for estimating repair costs.

What type of damage occurs in body panels adjacent to the primary impact zone due to transferred energy?

Answer: Secondary damage

Secondary damage occurs in areas surrounding the primary impact point as collision energy transfers through the structure.

A door gap that is wider at the top than at the bottom on one side is most indicative of which structural condition?

Answer: Sag damage

Sag damage causes the roof to drop downward, which results in door openings that are wider at the top than the bottom.

Which of the following paint defects is most commonly associated with collision repair that used improper heat during curing?

Answer: Blistering

Blistering in paint is typically caused by excessive heat during curing, which traps solvents or moisture beneath the film.

Corrosion found between two overlapping metal panels is known as:

Answer: Crevice corrosion

Crevice corrosion occurs in confined spaces between overlapping metal surfaces where moisture and contaminants accumulate.
