Repair Materials and Tools

Gun and brushes:

• Spray gun

NOTE: Any gun having a tip of more than 1.0 mm

(0.04 in) in diameter may be used for spraying the

primer.

• Viscosity measure

Iwata-type (IMS) cup, Ford cup

• Beaker

1-2 (1.05-2.10 US. qt, 0.9-2 Imp. qt) in capacity

• Stirring stick

Tools:

• Air or double action sander

• Sandpaper .(#240-#400)

Thinner and cleaner:

• Use the thinner specified for the primer.

• Any commercially available lacquer thinner may be used

to clean the gun.

Materials:

• Use primers equivalent to the ones shown in Types of

Chipping Guard Primer (Reference).

• Make sure to keep the thickness of the coat at 20

microns.

Masking:

• Masking tape, paper, vinyl sheet and plate (veneer and

steel).

• Masking plates are not necessary when spraying in a

booth.

Protectors:

• Wear an approved respirator or dust mask, gloves,

safety goggles and other protective clothing.

• Rags.

• 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.

Soft Chipping Guard Primer Coat

Coating Procedures

NOTE: This section covers the application of the soft

chipping primer to the replacement part.

1. Sanding the replacement part

Wear goggles or safety glasses to pre-

vent eye injury.

Sand the area to be painted with #240-#400 sand-

paper.

NOTE:

• Do not oversand the edges or corners of the part.

• Do not expose bare metal.

2. Air blowing/degreasing

NOTE: Measure the primer and hardener so they are in

correct ratio.

• Add the specified thinner to the mixture of hardener

and primer to attain the proper viscosity for spray-

ing.

2C 68’F (20’C) 18 sec 1

• These substances are not available in the USA Honda

recommends using DuPont’s 123 Vinyl Coating, or

Sherwin-Williams’ Vinyl Gravel Guard. Follow the

manufacturer’s instructions for application.

• Use the following materials:

• Spies Hecker Permacron 4:1 Surfacer 4:1 (Herberts)

• Standox 2K 4:1 Special Filler (Herberts)

• Once mixed with the hardener and thinner, the

primer must be used within the times shown below.

• 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.

• Paint thinner is flammable. Store it in a safe

place, and keep it away from sparks, flames or

cigarettes.

Clean the surface with compressed air and wax and

grease remover.

3. Masking

• Place masking tape or paper around the surface to

be painted.

• Cover as wide an area as possible with tape or paper

to keep primer from spreading.

4. Spraying chipping guard primer

• Stir the primer thoroughly.

• Put the primer in a beaker and weigh the needed

amount of primer to be used.

• Mix the hardener into the primer, following the

manufacturer’s instructions.

• 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 protec-

tion 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.

7. Intermediate and Top coating

• Sand the chipping guard primer film with #280-

#400 sandpaper.

• Follow the intermediate/top coating procedures (see

pages

8-9

and

8-10

).

• Fill the gun’s paint cup with the primer. Use a

strainer when pouring the primer into the cup.

• Primer should never be applied to a dirty or greasy

surface. Before spraying, blow dust and dirt off the

surface and clean with wax and grease remover.

(Method of spraying)

• Do not try to cover the surface with one heavy

coat. Apply several thin coats.

NOTE:

• Spray coat 4-5 coats to get 20 microns of thick-

ness, as one coat deposits 5-7 microns.

• Spray the primer at 250-300 kPa (2.5-3.0 kgf/

cm

2

, 35.6-42.7 psi) pressure. Spraying with im-

proper air pressure will cause imperfections.

• Open the gun 3-4 turns.

• Wipe up unwanted primer immediately with

thinner.

5. Cleaning spray gun

• After spraying, be sure to clean the spray gun

thoroughly with thinner or solvent.

• The gun will be perrnanently clogged if the primer is

allowed to dry.

6. Drying

• After spraying the chipping guard primer, air-dry for

7-10 minutes to evaporate the thinner in the

primer. Then dry it with infrared lamps at 176°F

(80°C) for 30-40 minutes.

NOTE: Insufficient baking may cause pinholes if the

primer coat is too thick.

• The temperature lamps and drying time

recommendations should be followed closely.

NOTE: The upper line of time shows specifications for High Primer Surfacer 2C, and the lower line Auto Primer Surfacer Mighty.
