to manufacturer specifications?
A. Hood panel
B. Radiator support
C. Front frame rails
D. Fender apron
,Rationale: The front frame rails are engineered to absorb and dissipate
crash energy; improper repair can compromise structural integrity and
occupant safety.
2. During paint preparation, what is the primary purpose of applying a
primer-sealer before basecoat application?
A. Increase paint gloss
B. Promote adhesion and uniform color coverage
C. Reduce drying time
