1. PROCESS STEPS
Process
No.Process name Job contents
1 Bumper mountingSet bumper on paint work table if required. Use
paint work table conforming to inner shape of
bumper when possible.
G5M0164
2 MaskingMask specified part (black base) with masking tape. Use masking tape for PP (e.g., Nichiban No.
533, etc.).
3Degreasing, clean-
ingClean all parts to be painted with white gasoline, normal alcohol, etc. to remove dirt, oil, fat, etc.
4 Primer paint First, apply one coat of primer to all parts to be painted, using air gun. Use primer (clear).
5 DryingDry at normal temperature [10 to 15 min. at 20°C (68°F)].
In half-dried condition, PP primer paint is dissolved by solvent, e.g. thinner, etc.
Therefore, if dust or dirt must be removed, use ordinary alcohol, etc.
6 Top coat paint (I)Solid color Metallic color
Use section (block) paint for top coat.

Paint in use (for each color):
Solid paint
Hardener PB
Thinner T-301

Mixing ratio:
Main agent vs. hardener = 4:1

Viscosity: 10—13 sec/20°C (68°F)

Film thickness: 35—45µ

Spraying pressure: 245—343 kPa
(2.5—3.5 kg/cm
2,36—50 psi)Use section (block) paint for top coat.

Paint in use (for each color):
Metallic paint
Hardener PB
Thinner T-306

Mixing ratio:
Main agent vs. hardener = 10:1

Viscosity: 10—13 sec/20°C (68°F)

Film thickness: 15—20µ

Spraying pressure: 245—343 kPa
(2.5—3.5 kg/cm2,36—50 psi)
7 Drying Not required.Dry at normal temperature [10 min. or more at
20°C (68°F)].
In half-dried condition, avoid dust, dirt.
8 Top coat paint (II) Not required.Apply a clear coat to parts with top coat paint (I),
three times, at 5—7 minutes intervals.

Paint in use:
Metallic paint
Hardener PB
Thinner T-301

Mixing ratio: Clear vs. hardener = 6:1

Viscosity: 14—16 sec/20°C (68°F)

Film thickness: 25—30µ

Spraying pressure: 245—343 kPa
(2.5—3.5 kg/cm
2,36—50 psi)
9 Drying60°C (140°F), 60 min. or 80°C (176°F), 30 min.
If higher than 80°C (176°F), PP may be deformed. Keep maximum temperature of 80°C (176°F).
