-2.Hardening starts immediately after mixing.
Practical hardness will be obtained within 60 min-
utes. The surface will be tacky within 5 minutes and
nearly hardened after 15 minutes. It takes 12 hours
for the surface to harden thoroughly 68°F (20°C)
-3.Sanding can be done after:
• Ventilate when spraying paint. Most paint
contains substances that are harmful if inhaled or
swallowed. Read the paint label before opening
the paint container.
• Avoid contact with skin. Wear an approved
respirator, gloves, eye protection and appropriate
clothing when painting.
• Paint is flammable. Store it in a safe place, and
keep it away from sparks, flames or cigarettes.
Drying time:
NOTE: The HIGH ART MAT BLACK SURFACER is a
dual liquid type. If mixed, it will harden in a matter of
hours.
3. Primer Surfacer
NOTE: Use a dual-liquid type bumper primer surfacer
(gray).
• The primer surface is used to protect the PP resin
surface and to fill cavities or flaws in the intermediate
and top coats.
• Mix 10 parts of primer surfacer and 1 part of har-
dener. Add the specific thinner (30-60%) to the
mixture of the hardener and primer to attain the
proper viscosity for spraying.
4. Intermediate and Top Paint Coats (Body color)
NOTE:
• The paints are the dual liquid type based on the color
chart.
• Measure the pigment and hardener as described so
they are in correct ratio.
• Use the acrylic urethane paint prepared according to
the mixing chart as the intermediate coat.
Mixing Ratio:
Mix 5 parts of body color pigment to 1 part of additive.
Mix 4 parts of the mixture of the pigment and additive
with 1 part of the hardener.
NOTE:
• Dilute the mixture with 40-50% of the specified
thinner (Highart Thinner).
• Be sure to mix the correct amount of the additive.
• Use a spray gun to apply the paint. Do not use a
brush.

Refinishing Procedures
1. Sanding damaged areas
Shallow scratch:
• Level and finish damaged areas with #240-#400
sandpaper.
• Polish the leveled area with #400 sandpaper.
NOTE:
• Use a flexible block to sand the surface evenly.
• Do not remove too much material.
NOTE: Be sure to use a tack cloth. Dust and dirt are
electrostatically drawn to the surface.
3. Applying bumper primer (clear type).
• Stir thoroughly before applying the primer. Use a
spray gun or brush depending on working condi-
tions.
• Ventilate when spraying paint. Most paint
contains substances that are harmful if inhaled
or swallowed. Read the paint label before
opening the paint container.
• Avoid contact with skin. Wear an approved
respirator, gloves, eye protection and
appropriate clothing when painting.
• Paint is flammable. Store it in a safe place, and
keep it away from sparks, flames or cigarettes.
• Cover as wide an area as possible, except for shallow
grooves (2-3 coats).
NOTE:
50°F (10°C).
• Apply the primer to the back of the bumper if the
damage is a tear or hole.
Deep groove/tear:
• Level and finish burrs and other irregularities with
#240 sandpaper. Keep the surface as even as
possible.
2. Degreasing/Cleaning
• 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.
• Clean with wax and grease remover and dry with
compressed air.
surface with a tack cloth.
4. Drying bumper primer.
Body parts being dried with an
industrial dryer can get hot enough to cause injury.
Do not touch parts being dried.
