Paint: Service and Repair
Refinishing Procedures
Refinishing Procedures
1. Featheredging (polishing damaged areas)
1. Damage to aluminum alloy base
-
Sand the damaged area flat and smooth with a double action sander and #60 or #80 disc paper.
-
Sand the boundary between the metal surface and undercoat with a double action sander and #180 or #280 disc paper. Try to sand a larger
area than the damage.
NOTE:
-
Make sure there is not height difference between the metal surface and undercoat.
-
If double action sander is not available, use a rubber block and wrap sandpaper around it to sand the surface.
WARNING: To prevent eye injury, wear goggles or safety glasses whenever sanding, cutting or grinding.
2. Damage to Undercoat
Intermediate coat 1
Intermediate coat 2
Top coat
Paint coat on replacement parts
Sand the damaged surface flat and smooth with a double action sander and #280 or #320 paper.
NOTE:
-
If double action sander is not available, use a rubber pad and wet or dry sand the surface with #280, #320, #400 or #600 sandpaper.
-
After sanding, check that the surface is flat and smooth.
-
Perform the operations in Item 1-1 above for the areas where parts are welded to the body.
2. Preparation of aluminum alloy base surface
Remove all corrosion from the damaged area using #180 or #280 paper.
3. Air Blowing/Degreasing
Air blow the sanded area, then degrease with a wax and grease remover (for USA usage-DuPont 38125 Enamel Reducer).
WARNING:
-
Do not use high air pressure: use only an approved, 210 kPa (2.1 kg/sq.cm, 30 psi) air nozzle.
-
Wear goggles or safety glasses to prevent eye injury.
4. Treatment of aluminum alloy base
-
Brush or spray a solution of chrome phosphate or washer primer to the exposed aluminum alloy base.
-
Use the following materials to treat the aluminum alloy base:
-
KAR washer primer (Kansai Paint) (for usage- DuPont)
-
110 active primer Agent (Nippon Paint)
-
G113 treatment (Isam Paint) (for USA usage- DuPont)
NOTE:
-
Follow the manufacturer's instructions.
-
Treat the aluminum alloy base surface, as much as possible, to provide a better bonding surface for the subsequent paint.
5. Application of Filler
Drying
Sanding
-
Small cracks or pinholes in the aluminum alloy base should be repaired with a filler and sanded flat and smooth.
NOTE:
-
Mix the filler to the hardener in the correct ratio.
-
Follow the filler manufacturer's instructions.
WARNING: 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 a 40-50 cm (16-20 in) from the filler while drying.
