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

(2) Set bumper section
2MaskingMask specified part (black base) with masking tape. Use masking tape for PP (example, Nichiban
No. 533, etc.).
3Degreasing, clean-
ingClean all parts to be painted with white gasoline, normal alcohol, etc. to remove dirt, oil, fat, etc.
4 Primer paint Apply primer one to all parts to be painted, using air gun. Use primer (clear).
5DryingDry at normal temperature [10 to 15 min. at 20°C (68°F)].
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.
6 Top coat paint (I)Solid color Metallic color
Use section (block) paint for top coat.
 Paint in use (for each color):

2. REPAIR INSTRUCTIONS FOR COLORED PP BUMPER
NOTE:
All PP bumpers are provided with a grained surface, and if the surface is damaged, it cannot normally be re-
stored to its former condition. Damage limited to shallow scratches that cause only a change in the lustre 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.
1) Minor damage causing only a change in the lustre of the bumper due to a light touch
Almost restorable.
2) Deep damage caused by scratching fences, etc.
A dent cannot be repaired but a whitened or swelled part can be removed.

1 Cleaning Clean the area to be repaired using water.
2 Sanding Grind the repairing area with #500 sand paper in a “feathering” motion.
3FinishResin section Coated section
Repeatedly apply wax to the affected area
using a soft cloth (such as flannel). Recom-
mended 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 subse-
quent operations in the “3)” section, depending
on the degree and nature of damage.
Polish the waxed area with a clean cloth after 5
to 10 minutes.

3) 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.)

1 Bumper removal Remove the bumper as required.
2 Part removal Remove the parts built into bumper as required.
3 Bumper placementPlace the bumper on a paint worktable as
required.
It is recommended that contour of worktable
accommodate internal shape of bumper.
(1) Bumper
(2) Set bumper section
4Surface prepara-
tionRemove dust, oil, etc. from areas to be repaired and surrounding areas, using a suitable 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 “vee-out”
the affected area using a knife or grinder.
(1) Paint surface
(2) PP base surface
(3) 20 — 30 mm (0.79 — 1.18 in)
(4) 3 mm (0.12 in)
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 sol-
vent.
Temporarily spot-weld the side, using a PP welding rod and heater gun.
(1) Welded spot (Use heater gun and PP welding rod)
(2) PP base surface
(3) Beveled section
N
OTE:
 Do not melt the welding rod until it flows out. This results in reduced strength.
 Leave 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 dam-
aged area.
(1) Melt hatched area
(2) Welding rod
(3) Section
N
OTE:
 Melt the sections indicated by hatched area.
 Do not melt the welding rod until it flows out, in order to provide strength.
 Always keep the heater gun 1 to 2 cm (0.4 to 0.8 in) away from the welding spot.
 Leave 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.
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
12Cleaning/
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 nec-
essary.
Recommended primer: Mp/ 364 PP Primer
N
OTE:
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 20°C (68°F) for 10 to 15 minutes until primer is half-dry.
N
OTE:
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.)
15Primer surfacer
coatingApply a coat of primer surfacer to the repaired area two or three times at an interval of 3 to 5 min-
utes.
Recommended surfacer:
 UPS 300 Flex Primer
 No. 303 UPS 300 Exclusive hardener
 NPS 725 Exclusive Reducer (thinner)
 Mixing ratio: 2: 1 (UPS 300: No. 303)
 Viscosity: 12 — 14 sec/20°C (68°F)
 Coated film thickness: 40 — 50µ
16 Drying Allow the coated surface to dry for 60 minutes at 20°C (68°F) [or 30 minutes at 60°C (140°F)].
17 Sanding (III) Sand the coated surface and its surrounding areas using #400 sand paper and water.
