BODY REPAIR
1. When repairing and painting a portion of the body adjacent to plastic parts, consider their characteristics
(influence of heat and solvent) and remove them if necessary or take suitable measures to protect them.
2. Plastic parts should be repaired and painted using methods suiting the materials
,
characteristics.

Precaution in Repairing High Strength Steel
INFOID:0000000006245355
High strength steel is used for body panels in order to reduce vehicle weight.
Accordingly, precautions in repairing automotive bodies made of high strength steel are described below:
High strength steel (hss) used in nissan vehicles
SP130 is the most commonly used HSS.
SP150 HSS is used only on parts that require much more strength.
Read the following precautions when repairing HSS:
1. Additional points to consider
• The repair of reinforcements (such as side members) by heat-
ing is not recommended since it may weaken the component.
When heating is unavoidable, do not heat HSS parts above
550
°
C (1,022
°
F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropri-
ate.)

• When straightening body panels, use caution in pulling any
HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.
• When cutting HSS panels, avoid gas (torch) cutting if possible.
Instead, use a saw to avoid weakening surrounding areas due
to heat. If gas (torch) cutting is unavoidable, allow a minimum
margin of 50 mm (1.97in).
• When welding HSS panels, use spot welding whenever possi-
ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.
• The spot weld on HSS panels is harder than that of an ordi-
nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a low
speed high torque drill (1,000 to 1,200 rpm) to increase drill bit
durability and facilitate the operation.
• SP150 HSS panels with a tensile strength of 785 to 981 N/
mm

(80 to 100 kg/mm

, 114 to 142 klb/sq in), used as rein-
forcement in the door guard beams, is too strong to repair.
When these HSS parts are damaged, the outer panels also
sustain substantial damage; therefore, the assembly parts
must be replaced.

2. Precautions in spot welding HSS
This work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:
• The electrode tip diameter must be sized properly according to
the metal thickness.
• The panel surfaces must fit flush to each other, leaving no
gaps.
• Follow the specifications for the proper welding pitch.

Foam Repair
INFOID:0000000006245356
During factory body assembly, foam insulators are installed in certain body panels and locations around the
vehicle. Use the following procedure(s) to replace any factory-installed foam insulators.
URETHANE FOAM APPLICATIONS
Use commercially available spray foam for sealant (foam material) repair of material used on vehicle. Read
instructions on product for fill procedures.
