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

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
and
).
• 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.
