9. Spraying dual-liquid bumper primer surfacer (gray)

NOTE: Use the urethane bumper primer.

NOTE: Use #600 or finer sandpaper as any paper

coarser than this might scratch the surface.

• Do not use high air pressure; use only an ap-

proved, 210 kPa (2.1 kgf/cm

2

, 30 psi) air nozzle

• Wear goggles or safety glasses to prevent eye

injury.

-2. Air blow the surface to be repaired, then degrease

with a wax and grease remover.

-3. Also clean and degrease where masking tape will be

attached.

11. Intermediate coating

NOTE: Intermediate coating is recommended

for bright colors.

• Use the top coat enamel.

• Ventilate when spraying paint. Most paint

contains substances that are harmful if inhaled

or swallowed. Read the paint label before

opening the paint container.

• Avoid contact with skin. Wear an approved

respirator, gloves, eye protection and

appropriate clothing when painting.

• Paint is flammable. Store it in a safe place, and

keep it away from sparks, flames or cigarettes.

Spray the primer surfacer over a wider area than the

filler and the exposed surfaces of bumper primer.

NOTE: Spray 2-3 coats to get 20-25 microns of thick-

ness.

Mixing Ratio: (Reference)

• Ventilate when spraying paint. Most paint

contains substances that are harmful if inhaled

or swallowed. Read the paint label before

opening the paint container.

• Avoid contact with skin. Wear an approved

respirator, gloves, eye protection and

appropriate clothing when painting.

• Paint is flammable. Store it in a safe place, and

keep it away from sparks, flames or cigarettes.

• Mix the additive into the solid enamel color, metallic

enamel or pearl enamel color in the ratio of 1 to 5 (by

weight).

• Mix the hardener into the mixture of pigment and

additive described above in the ratio of 1 to 4 (by

weight).

NOTE: Keep the correct ratio, especially of the

additive. Excessive additive takes longer to dry.

• Adjust to the proper viscosity for spray by adding the

thinner specified for the primer into the mixture of

primer additive and hardener.

Viscosity: 68°F (20°C) 11-13 sec.

10. Drying and polishing

Force dry the primer surfacer with infrared lamps or

other industrial dryer.

Body parts being dried with an

industrial dryer can get hot enough to cause injury.

Do not touch parts being dried.

Drying temperature:

NOTE:

• Use a dryer whenever possible.

• Do not allow the temperature to exceed 158°F

(70°C).

-1. After force drying, wet sand the primer surface with

#600 sandpaper.

Refinishing Procedures (cont’d)

NOTE: It is not necessary to apply the clear coat.

• Spray 2-3 coats of the top coat enamel to get 15-20

microns of thickness. The primer surfacer (gray)

should not show through the top coat.

NOTE:

• Apply the top coat enamel to the repaired surface.

• Apply the top coat enamel to the entire surface of

the primer surfacer when replacement is necessary.

12. Degreasing and Cleaning

Air dry the entire surface, then clean with wax and

grease remover (for USA usage-Dupont 38125 Enamel

Reducer).

NOTE: For shading or spot painting, polish the area

with a polishing compound. Also sand with a #1500

paper to make a better bonding surface for the paint.

14. Top Coating

• Air dry and degrease the surface before spraying the

paint. Also clean the surface with a tack cloth.

13. Masking

• Remove all existing masking paper, then mask with

new paper.

• Use a heat resistant type masking tape (SCOTCH

TAPE) where tape is attached directly to the

bumper.

• Use brown paper or masking roll paper to cover.

NOTE:

• Mask the area completely to prevent overspray.

• Protect resin parts with aluminum foil under the

brown paper or masking paper to prevent damage

due to heat during baking.

• Ventilate when spraying paint. Most paint

contains substances that are harmful if inhaled

or swallowed. Read the paint label before

opening the paint container.

• Avoid contact with skin. Wear an approved

respirator, gloves, eye protection and

appropriate clothing when painting.

• Paint is flammable. Store it in a safe place, and

keep it away from sparks, flames or cigarettes.

• Remove dust and dirt from the surface to be coated

with compressed air, then use a tack cloth.

• Use a strainer when filling the cup with paint.

• Spray the paint evenly over the surface so the

replacement part is completely covered.

• For application of the top coating refer to step 11

» Intermediate coating.»

NOTE: Do not try to cover the surface with one heavy

coat. Apply several thin coats.

• With solid color (2-coat type), metallic color and

pearl color enamels, allow final coat to flash-off
(5-20 minutes) before applying clear coat.

• Mix the additive into the clear in the ratio of 1 to 5.

Adding the hardener and adjusting viscosity should

be done the same way as described on the previous

page.

Viscosity. 68°F (20°C) 13-15 sec.

15. Drying top coat

Body parts being dried with an

industrial dryer can get hot enough to cause injury.

Do not touch parts being dried.

• Before force drying, let it air dry for 5-10 minutes.

• Force dry the sprayed surface under the infrared

lamps for 60-90 minutes.

• Keep the drying temperature between 140°F (60°C)

and 158°F (70°C).

NOTE: Take care not to let the heat deform the part

during the drying process.

16. Polishing and Buffing

• Let the paint dry gradually, then polish the surface

carefully using a polishing compound and sponge

buff.

• To remove lint or dirt, wet sand the surface with

#2000 or finer paper first, then polish with com-

pound.

NOTE: Polish all roughness caused by sanding

thoroughly. To do this, first polish with very fine

compound, then with ultra fine compound.

• After polishing, remove the masking paper and

tape and wash the entire vehicle thoroughly.

ABS/PC Resin Parts

General

The door mirror housing, license plate trim, and front grille are made ABS resin.
They can be repaired if the damage or deformation is minor in nature. This section covers ABS repair. Repairing ABS is different from

other resins such as PP and urethane.

NOTE:

• The ABS resin is the copolymer resin consisting of the three monomers of acrylonitrile, butadiene, and styrene.

• Polycarbonate is a generic name for high polymers which have the carbonic ester structure in the structural unit. The most

prominent feature of polycarbonate is its tensile strength which shows the same level of yielding point as metals in the normal

temperature. It also has outstanding impact strength compared to other plastics.

NOTE: The following repair procedures also apply

to the door outer handle (PC).

Repair Materials

Examples:

Adhesive and filler: Epoxy

• Kemit TE2301 bond quick mender

Filler:

• R-M Stop zinc (R-M)

• 3M 5900 Repair Material (Akzo)

NOTE: Follow the manufacturer’s specification.

Top coat:
