9. Spraying dual-liquid bumper primer surfacer (gray) NOTE: Use the urethane bumper primer. NOTE: Use #600 or finer sandpaper as any paper coarser than this might scratch the surface. • 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. -2. Air blow the surface to be repaired, then degrease with a wax and grease remover. -3. Also clean and degrease where masking tape will be attached. 11. Intermediate coating NOTE: Intermediate coating is recommended for bright colors. • Use the top coat enamel. • 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 surfacer over a wider area than the filler and the exposed surfaces of bumper primer. NOTE: Spray 2-3 coats to get 20-25 microns of thick- ness. Mixing Ratio: (Reference) • 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. • Mix the additive into the solid enamel color, metallic enamel or pearl enamel color in the ratio of 1 to 5 (by weight). • Mix the hardener into the mixture of pigment and additive described above in the ratio of 1 to 4 (by weight). NOTE: Keep the correct ratio, especially of the additive. Excessive additive takes longer to dry. • Adjust to the proper viscosity for spray by adding the thinner specified for the primer into the mixture of primer additive and hardener. Viscosity: 68°F (20°C) 11-13 sec. 10. Drying and polishing Force dry the primer surfacer with infrared lamps or other industrial dryer. Body parts being dried with an industrial dryer can get hot enough to cause injury. Do not touch parts being dried. Drying temperature: NOTE: • Use a dryer whenever possible. • Do not allow the temperature to exceed 158°F (70°C). -1. After force drying, wet sand the primer surface with #600 sandpaper.
