1 Bumper mountingSet bumper on paint work table if required.
Use paint work table conforming to inner
shape of bumper when possible.

2 MaskingMask specified part (black base) with masking tape. Use masking tape for PP (e.g.,
Nichiban No. 533, etc.).
3 Degreasing, cleaningClean all parts to be painted with white gasoline, normal alcohol, etc. to remove dirt,
oil, fat, etc.
4 Primer paintFirst, apply one coat of primer to all parts to be painted, using air gun. Use primer
(clear).
5 DryingDry at normal temperature [10 to 15 min. at 20ÉC (68ÉF)].
In half-dried condition, PP primer paint is dissolved by solvent, e.g. thinner, etc.
Therefore, if dust or dirt must be removed, use ordinary alcohol, etc.

7. Repair Instructions for Colored PP Bumper
All PP bumpers are provided with a grained surface, and if the surface is damaged, it cannot normally be
restored to its former condition. Damage limited to shallow scratches that cause only a change in the lus-
tre of the base material or coating, can be almost fully restored. Before repairing a damaged area, explain
this point to the customer and get an understanding about the matter.
Repair methods are outlined below, based on a classification of the extent of damage.
A: MINOR DAMAGE CAUSING ONLY A CHANGE IN THE LUSTRE OF THE
BUMPER DUE TO A LIGHT TOUCH
It is almost restorable as follows:
Process
No.Process name Job contents
1 Cleaning Clean the area to be repaired using water.
2 Sanding Grind the repairing area with #500 sand paper in a ªfeatheringº motion.
3 FinishResin section Coated section
Repeatedly apply wax to the affected area
using a soft cloth (such as flannel).
Recommended wax: NITTO KASEI Soft
99 TIRE WAX BLACK, or equivalent.Perform either the same operation as for
the resin section or process No. 18 and
subsequent operations in the ª3.º section,
depending on the degree and nature of
damage. Polish the waxed area with a
clean cloth after 5 to 10 minutes. Polish the waxed area with a clean cloth
after 5 to 10 minutes.
B: DEEP DAMAGE CAUSED BY SCRATCHING FENCES, ETC.
A dent cannot be repaired but a whitened or swelled part can be removed.
Process
No.Process name Job contents
1 Cleaning Clean damaged area with water.
2Removal of damaged
areaCut off protruding area, if any, due to collision, using a putty knife.
3 Sanding Grind the affected area with #100 to #500 sand paper.
4 FinishResin section Coated section
Same as process No. 3 in the ª1.º section.Perform process No. 12 and subsequent
operations in the ª3.º section.
C: DEEP DAMAGE SUCH AS A BREAK OR HOLE THAT REQUIRES FILLING
Much of the peripheral grained surface must be sacrificed for repair, and the degree of restoration is not
really worth the expense. (The surface, however, will become almost flush with adjacent areas.)
Recommended repair kit: PP Part Repair Kit (NRM)

1 Bumper removal Remove bumper as required.
2 Parts removal Place bumper on a paint work table as required.
3 Bumper placementPlace bumper on a paint work table as
required. It is recommended that contour
of work table accommodates internal
shape of bumper.
G5M0164
4 Surface preparationRemove dust, oil, etc. from areas to be repaired and surrounding areas, using a suit-
able solvent (NRM No. 900 precleno, white gasoline, or alcohol).

5 CuttingIf nature of damage are cracks or holes,
cut a guide slit of 20 to 30 mm (0.79 to
1.18 in) in length along the crack or hole
up to the bumper's base surface. Then,
bevel or ªvee- outº the affected area using
a knife or grinder.
G5M0165
6 Sanding (I) Grind beveled surface with sand paper (#40 to #60) to smooth finish.
7 Cleaning Clean the sanded surface with the same solvent as used in process No. 4.
8 Temporary weldingGrind the side just opposite the beveled area with sand paper (#40 to #60) and clean
using a solvent.
Temporarily spot-weld the side, using a PP welding rod and heater gun.
G5M0166
NOTE:
IDo not melt welding rod until it flows out. This results in reduced strength.
ILeave the welded spot unattended until it cools completely.
9 WeldingUsing a heater gun and PP welding rod, weld the beveled spot while melting the rod
and damaged area.
G5M0167
NOTE:
IMelt the sections indicated by hatched area.
IDo not melt welding rod until it flows out, in order to provide strength.
IAlways keep the heater gun 1 to 2 cm (0.4 to 0.8 in) away from the welding spot.
ILeave the welded spot unattended until it cools completely.

10 Sanding (II)Remove excess part of weld with a putty knife. If a drill or disc wheel is used instead
of the knife, operate it at a rate lower than 1,500 rpm and grind the excess part little by
little. A higher rpm will cause the PP substrate to melt from the heat.
G5M0168
Sand the welded spot smooth with #240 sand paper.
11 MaskingMask the black substrate section using masking tape.
Recommended masking tape: Nichiban No. 533 or equivalent
12 Cleaning/ degreasingCompletely clean the entire coated area, using solvent similar to that used in process
No. 4.
13 Primer coatingApply a coat of primer to the repaired surface and its surrounding areas. Mask these
areas, if necessary.
Recommended primer: Mp/ 364 PP primer
NOTE:
Be sure to apply one coat of primer at a spraying pressure of 245 to 343 kPa (2.5 to
3.5 kg/cm
2, 36 to 50 psi) with a spray gun.
14 Leave unattended.Leave the repaired area unattended at 20ÉC (68ÉF) for 10 to 15 minutes until primer is
half-dry.
NOTE:
If dirt or dust comes in contact with the coated area, wipe it off with a cloth dampended
with alcohol. (Do not use thinner since the coated area tends to melt.)
15 Primer surfacer coatingApply a coat of primer surfacer to the repaired area two or three times at an interval of
3 to 5 minutes.
