Body Paint6-3

General

The 3-coat·3-bake (3C·3B) paint finishes give the CR-V a deep gloss and stunning finish. This manual provides information on paint defect, repair, and refinishing. Throughout, the objective is to explain in a simple yet comprehensive manner the basic items you should know about paint repairs. Select the correct material for the defect and repaint or refinish in the correct manner as described in this manual.

WARNING

  • Most paints contain substances that are harmful if inhaled or swallowed. Read the paint label before opening the container.
  • Spray paint only in a well ventilated area.
  • Cover spilled paint with sand, or wipe it up at once.
  • Wear an approved respirator, gloves, eye protection, and appropriate clothing when painting. Avoid contact with skin.
  • If paint gets in your mouth or on your skin, rinse or wash thoroughly with water. If paint gets in your eyes, flush with water and get prompt medical attention.
  • Paint is flammable. Store it in a safe place, and keep it away from sparks, flames, or cigarettes.



    • Basic Rules for Repairing a Paint Finish

    To repair paint damage, always use the 2-part acylic urethane paints designated; polish and bake each of the three coats, as in production, to maintain the original film thickness, and to assure the same quality as the original finish.

    Outline of Factory Painting Process:


    Features in Each Work Process
    1. Pretreatment and Electrodeposition
    2. In the pretreatment process, the entire body is degreased, cleaned, and coated with zinc phosphate by dipping.
    3. After the body has been cleaned with pure water, it is placed in an electrolytic bath of soluble primer (Cationic Electrodeposition).
    4. This produces a thorough corrosion inhibiting coating on the inner surface and corners of the body, pillars, sills, and panel joints.
    5. Chipping primer is then applied to the most susceptibles areas (see page 5-9) .
    6. Intermediate coat
    7. The intermediate coat is applied to the prepared surface for further protection against damage.
    8. Top Coat
    9. Enamel paint and either polyester or acrylic resin paint are used in the top coat for higher solidity, smoothness, brightness, and weather resistance.

    Preprocessing of Painting

    1. Featheredging
    2. NOTE:
    3. The paint film damaged area should be sanded flat and smooth.
    4. If this is not done correctly the end results will not be acceptable.


    Damage to metal surface:

  • Sand the damaged area flat and smooth.

    Use the disc sander and #60~#80 disc paper.





    Use the double action sander and #60~#80 disc paper.





  • Sand the area larger than the damaged area.

    Use the double action sander and #180~#240 disc paper.





  • If a double action sander is not available, use a rubber pad and wet or dry sandpaper.

    Use the flexible block and #280, #340, #400, #600 sandpaper.




    • Damage to undercoat, intermediate coat and top coat:

  • Sand the damage area flat and smooth

    Use the double action sander and #180~#240~#320 disc paper.





    1. Preparation of metal surface
    2. Remove all corrosion from the damaged area.

      Use a product that removes corrosion.





    3. Air blowing / degreasing

      Use alcohol, wax, and grease remover.

    Treatment of Metal Surface

    1. Filling / drying
    2. Small cracks or pinholes in the sheet metal should be repaired with a body filler and sanded flat and smooth.

    3. Use the 2-part polyester resin putty.
    4. Mix the putty with the hardener in the correct ratio.
    5. Follow the body filler manufacturer's instructions.




    6. Mix the body filler and hardener quickly.


    7. Apply the body filler in several thin coats, without air bubbles.
    8. Do not try to cover the surface with one heavy coat.
    9. Apply the body filler over the damaged area with a putty knife using light pressure.


    10. After applying the body filler, allow 5 to 6 minutes of normal drying time, then force dry it with infrared lamps or other industrial dryer at 122°F (0°C)~140°F (60°C).
    11. NOTE: Follow the body filler manufacturer's instructions for drying time.
    12. Polishing
