1. A Maryland Auto Body Repair Technician is preparing to refinish a
repaired quarter panel. Before applying primer, the technician notices
traces of wax and grease contamination on the surface. What is the
MOST appropriate initial corrective action?
A. Apply additional primer surfacer to seal the contamination
B. Sand the panel with coarse grit paper only
C. Remove contaminants using an approved wax and grease remover
D. Heat the panel with a heat gun until the residue disappears
C. Remove contaminants using an approved wax and grease remover
Proper surface preparation is critical before refinishing operations. Wax,
grease, silicone, and other contaminants can cause fisheyes, adhesion
failure, and paint defects. Approved cleaning agents should be used prior
to sanding or coating application to ensure proper adhesion and finish
quality.
, 2. During structural repairs, a technician discovers that a unibody vehicle
has sustained damage to the front frame rail. Which equipment is
MOST appropriate for measuring structural alignment accuracy?
A. Brake lathe
B. Electronic measuring system
C. Tire balancer
D. Vacuum gauge
B. Electronic measuring system
Electronic measuring systems provide precise dimensional analysis of
structural components in unibody vehicles. Accurate measurements are
essential to ensure proper alignment, crashworthiness, and manufacturer
specification compliance after collision repairs.
3. Which welding process is MOST commonly used in modern collision
repair facilities for replacing steel body panels?
A. Oxyacetylene welding
B. MIG welding
C. TIG welding
D. Resistance spot welding only
B. MIG welding
MIG welding is widely used in collision repair because it provides efficient,
strong welds suitable for automotive steel panel replacement. It is
versatile, relatively easy to learn, and commonly recommended by vehicle
manufacturers for many repair procedures.
4. A technician is sanding body filler before applying primer. Which grit
range is generally MOST appropriate for final shaping prior to primer
application?
,A. 24–36 grit
B. 40–60 grit
C. 80–180 grit
D. 400–600 grit
C. 80–180 grit
Body filler is commonly rough-shaped with coarse abrasives and then
refined using medium grits such as 80–180 before primer application. This
creates an adequately smooth surface while maintaining proper primer
adhesion.
5. Which safety precaution is MOST important when working around
supplemental restraint systems (SRS)?
A. Disconnecting the horn relay only
B. Inflating airbags before removal
C. Disconnecting battery power and following OEM procedures
D. Spraying lubricant into connectors
C. Disconnecting battery power and following OEM procedures
Supplemental restraint systems contain explosive devices and sensitive
electronics. Following manufacturer procedures and disconnecting battery
power helps prevent accidental deployment and serious injury during
repairs.
6. What is the PRIMARY purpose of applying seam sealer during collision
repair?
A. Increase panel flexibility
B. Improve fuel economy
C. Prevent moisture intrusion and corrosion
D. Reduce paint drying time
C. Prevent moisture intrusion and corrosion
, Seam sealer protects repaired joints and seams from water intrusion,
which can lead to corrosion and structural deterioration. It also helps
reduce noise and restore OEM sealing characteristics.
7. A technician notices orange peel texture after refinishing a vehicle
panel. Which factor MOST commonly contributes to this condition?
A. Excessively fine sanding scratches
B. Improper spray gun setup or application technique
C. Excessive curing time
D. Low tire pressure
B. Improper spray gun setup or application technique
Orange peel is typically caused by incorrect spray gun settings, improper
viscosity, poor atomization, or incorrect spraying technique. Proper
equipment adjustment and application practices are essential for achieving
a smooth finish.
8. Which tool is MOST appropriate for removing minor dents without
damaging surrounding paint?
A. Slide hammer
B. Stud welder
C. Paintless dent repair tools
D. Plasma cutter
C. Paintless dent repair tools
Paintless dent repair techniques use specialized tools to massage dents
from behind panels without disturbing the original paint finish. This
method is effective for minor dents where paint damage has not occurred.
9. Why is featheredging performed during panel refinishing preparation?
