Indicates undercoated portions

The
undersides ofthe floor andwheelhouse areundercoated toprevent rust,vibration, noiseandstone
chipping.
Therefore, whensuchapanel isreplaced orrepaired, applyundercoating tothat part. Useanundercoating with
the following properties: rustpreventive, soundproof, vibration-proof, shock-resistant, adhesive,anddurable.
Precautions inundercoating
1. Donot apply undercoating toany place unless specified (suchasthe areas above themuffler andcatalytic
converter whicharesubjected toheat).
2. Donot undercoat theexhaust pipe,other partswhich become hot,androtary parts.
3. Apply bitumen waxafter applying undercoating.

• When ameasuring tapeisused, check tobe sure there isno elongation, twistingorbending.
• Measurements shouldbetaken atthe center ofthe mounting holes.
• Anasterisk

•
The electrode tipdiameter mustbereformed
properly according tothe panels thickness.
•
The spot ungget onHSS panel isharder than
that ofan ordinary steelpanel.
Therefore, forspot cutting HSSpanel, ahigh
torque drillofalow speed (1,000 to1,200
rpm) maybeused tomaintain itsdurability
and facilitate theoperation.

used asreinforcement inthe door guard barand inthe bumper, istoo high intensile strength touse
for general repairs.Whenthesepanels aredamaged, theouter panels alsosustain consequential
damage; therefore, thesepanels arenever remedied withoutreplacing thedoor assembly orbumper
assembly.

• The repair ofreinforcements (suchasside
members) byheating isnot recommended
since itinvolves theriskoflowering strength.
When heating isunavoidable, donot heat
such parts attemperatures above550°C (1,

022°F)

Heating temperature shouldbeverified with
a thermometer. (Acrayon-type andother
thermometer areavailable.)
• When straightening bodypanels, usecaution
in pulling anyHSS panel. Because itis very
strong, thismay cause deformation inadja-
cent portions ofthe body. Inthis case,
increase thenumber ofmeasuring points,
and carefully pulltheHSS panel.
Special
consideration forHSS must begiven tothe following points:
1 .Additional pointstoconsider
• Incutting HSSpanel, avoidgascutting if
possible. Instead,useanairsaw orahand
cutter toavoid decreasing thestrength of
surrounding portionsduetothe influence of
heat. Incase gascutting isinevitable, a
minimum allowance of50 mm (1.97 in)
must begiven.
