Refinishing Procedures

Refinishing Procedures

1. Base material reconditioning (sanding)

1. Replacement part
Lightly sand both sides of the part.
2. Slight scores or scratches
Use a flexible sanding block and wet-sand the damaged section with #400, #600.

NOTE: Sand level to remove damage.

3. Deep scratches, When filling

Use a flexible sanding block and wet-sand the damaged section with #180, #280.

NOTE: Perform the featheredging on the material surface and coat surface (primer, intermediate coat, and top coat) thoroughly and properly.

2. Degreasing, and cleaning
Clean the repair area with wax and grease remover, then blow with air dry.

WARNING:
- Do not use high air pressure; use only an approved, 210kPa (2.1 kg/sq.cm, 30 psi) air nozzle.
- Wear goggles or safety glasses to prevent eye injury.

NOTE: Wipe dust off the surface with a tack cloth.

3. Primer application
- Apply to the deep scratches and areas to be filled. This procedure might not be required by some manufacture's, products.
- Spray wider than the damaged section (i.e. area to be filled) two or three times.

NOTE: Follow the manufacturer's specification.

4. Coating with primer surfacer and drying

NOTE: Some manufacturers might require puttying before performing this step.

Spray the primer surfacer wider than the filled area and the exposed base material.
The spray guideline should be 20-23 microns.

WARNING:
- Ventilate when spraying paint. Most paint contains substances that are harmful if inhaled or swallowed. Read the paint label before opening paint container.
- Avoid contact with skin. Wear an approved respirator, gloves, eye protection and appropriate clothing when painting.
- Paint is flammable. Store in a safe place, and keep it away from sparks, flames or cigarettes.

NOTE: Follow the manufacturer's instructions.

- After coating with the primer surfacer, let the primer surfacer dry naturally for 5 to 10 minutes then dry the paint film of the primer surfacer with an infrared dryer.
- While drying the primer surface with the dryer, be sure to keep the dryer 40-50 cm (16-20 in) away from the paint film.

WARNING: Body parts being dried with an industrial dryer can get hot enough to cause injury. Do not touch parts being dried.

5. Filling drying and sanding

- The exposed base material could be directly filled, depending on the manufacturer's specification.
- Be sure that the primer surfacer is dried completely.
- Lightly dry sand the primer surfacer paint film with the #240 paper.
- Apply the filler in several thin coats.

NOTE: Mix and apply the filler according to the manufacturer's instructions.

- Dry the filler with an infrared dryer for 5 or 6 minutes.
- While drying the filler with the dryer, be sure to keep the dryer 40-50 cm (16-20 in) away from the surface.
- Scratch the filled surface with your nail. If the surface is white when scratched, dry sand and wet-sand with the #280, #320 paper. Be sure to sand level.

6. Cleaning with compressed air, and degreasing
Blow the entire area that is to be coated with primer surfacer with compressed air, then clean with wax and grease remover.

WARNING:
- Do not use high air pressure; use only an approved, 210kPa (2.1 kg/sq.cm, 30 psi) air nozzle.
- Wear goggles of safety glasses to prevent eye injury.

NOTE: Also wipe the masking area to help the masking tape adhere securely.

7. Masking
- Mask the area that should not be sprayed with the primer surfacer.
- Use the masking tape and paper to mask.

8. Coating with primer surfacer and drying
- Spray the two primer surfacer over the filled area.
- The spray guideline should be 20-25 microns.

NOTE: Follow the primer surfacer manufacturer's instructions.

- After coating with the primer surfacer, let the primer surfacer dry naturally for 5 to 10 minutes, then dry with an infrared dryer.

WARNING: Body parts being dried with an industrial dryer can get hot enough to cause injury. Do not touch parts being dried.

- While drying with the dryer, be sure to keep the dryer 40-50 cm (16-20 in) away from the paint film.

9. Sanding, and cleaning
Lightly wet-sand the whole area to be painted with # 600 sandpaper. Blow off with compressed air, then clean with wax and grease remover.

10. Top coating
- Remove dust with a tack cloth before top coating.
- Spray the top coat paint.
Spray until the primer surfacer is covered. The
spray guideline should be 30-35 microns.

WARNING:
- Ventilate when spraying paint. Most paint contains substances that are harmful if inhaled or swallowed. Read the paint label before opening paint container.
- Avoid contact with skin. Wear an approved respirator, gloves, eye protection and appropriate clothing when painting.
- Paint is flammable. Store in a safe place, and keep it away from sparks, flames or cigarettes.
- Do not use high air pressure; use only an approved, 210kPa (2.1 kg/sq.cm, 30 psi) air nozzle.
- Wear goggles or safety glasses to prevent eye injury.

NOTE: For the recommended top coat paint, refer to the "4. Top coat" of "Example of repair materials".

Solid: Color enamel color clear coat
Metallic: Metallic enamel clear coat
Pearl: Pearl enamel clear coat

11. Drying
After top coating about 10 minutes, then dry with an infrared dryer.

NOTE: Follow the paint manufacturer's specification to dry properly.
