Body Repair Manual

Refinishing Procedures (cont'd)
Paint
Body parts being dried with an
industrial dryer can get hot enough to cause injury-
Do not touch parts being dried.
• Allow the filler to air dry for about 5-6 minutes,
then force dry with an infrared lamp.
NOTE: Keep the lamp 40-50 cm (16-20 in) from the
filler while drying.
• Stop drying the filler if a white mark appears when
the surface is scratched with your nail. Wet or dry
sand the surface flat and smooth with a #280 or
#320 paper.
6. Air Blowing/Degreasing
Air blow the surface to be repaired, then degrease with
a wax and grease remover (for USA usage-Dupont
38125 Enamel Reducer).
NOTE: Also clean and degrease surfaces where masking
tape will be attached.
7. Masking
Mask the areas surrounding the damage to prevent
overspray from the primer.
8. Application and Drying of Primer/Drying
• 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.
• Spray the primer over the filler and surface (use
epoxy or urethane 2-part primer).
Spray : 2-3 coats.
• Use the following materials:
• 615S Primer Surfacer (DuPont)
• Primer Surfacer EP (Akzo)
• NPS735 Urethane Primer Surfacer (R-M)
• Let the primer air dry for 5-10 minutes, then force
dry with a infrared lamp.
NOTE: Keep the dryer 40-50 cm (16-20 in) from the
surface.
9. Polishing Undercoat
• Remove the masking paper and tape.
• Check that the undercoat has dried thoroughly, then
dry or wet sand the surface with a #280 or #320
paper.
NOTE:
• Use a rubber block and sand flat and smooth.
• Sand the entire surface to be refinished.
10. Air Blowing/Degreasing
• 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.
Air blow all the surfaces, then degrease with wax and
grease remover (for USA usage-DuPont 38125 Enamel
Reducer).
NOTE: Also degrease the surfaces where masking tape
will be attached.
11. Masking
Mask the undamaged areas surrounding the damage to
prevent overspray from primer surfacer (undercoat).
NOTE: Use masking tape and paper to mask the body.
A vinyl cover may also be used to effectively mask the
body.
