ASE Non-Structural Analysis & Damage Repair 3 — Questions and Answers
Question 1: Corrosion protection on the inside of a repaired box section is best applied using what?
- Cavity wax through access holes (Correct answer)
- Body filler
- Exterior clearcoat
- Seam sealer only
Correct answer: Cavity wax through access holes
Cavity wax sprayed through access holes coats enclosed interior surfaces that primer cannot reach.
Question 2: Before welding near fuel or brake lines, the technician should always do what?
- Remove or shield the lines and disconnect the battery (Correct answer)
- Increase weld amperage
- Apply seam sealer over the lines
- Leave the lines pressurized
Correct answer: Remove or shield the lines and disconnect the battery
Lines must be removed or shielded and the battery disconnected to prevent fire and electrical damage.
Question 3: A pull on a unibody panel that uses multiple anchor points primarily serves to do what?
- Hold the vehicle and counter the pulling force (Correct answer)
- Add weight to the frame
- Heat the metal
- Apply paint evenly
Correct answer: Hold the vehicle and counter the pulling force
Multiple anchors hold the vehicle securely and counteract the directional pulling forces.
Question 4: What does a body technician use to find low and high spots on a smoothed panel?
- A body file or guide coat (Correct answer)
- A torque wrench
- A multimeter
- A compression gauge
Correct answer: A body file or guide coat
A body file or guide coat reveals highs and lows by cutting or leaving paint in the contours.
Question 5: When replacing a bolt-on fender, corrosion protection should be applied where?
- On mating surfaces and fasteners (Correct answer)
- Only on the visible outer skin
- Nowhere, since it is bolted
- Only on the headlight bucket
Correct answer: On mating surfaces and fasteners
Mating surfaces and fasteners trap moisture, so they require corrosion protection during assembly.
Question 6: Cold straightening of high-strength steel is recommended because heat can do what?
- Reduce the steel's engineered strength (Correct answer)
- Increase its hardness permanently
- Improve weld penetration
- Make it more corrosion resistant
Correct answer: Reduce the steel's engineered strength
Heating high-strength steel can reduce its engineered strength, so cold methods are preferred.
Question 7: Which type of plastic repair material is used for flexible bumper covers?
- Flexible two-part adhesive or filler (Correct answer)
- Rigid metal filler
- Lead solder
- Epoxy primer only
Correct answer: Flexible two-part adhesive or filler
Flexible repair materials move with the bumper cover and resist cracking under flexing.
