Process Description of work
1. Preparing faulty areas for
repainting
Remove graining and runs by wet-rubbing with #400 sandpaper, and after
the surface is smooth, finish by wet-rubbing with #600 – 800 sandpaper.
If there are areas where the paint film is insufficiently thick, wet-rub them
with #800 sandpaper.
If there are areas on the outside of the above which are to be coated with
clear paint, wet-rub them with #1500 sandpaper.
2. Degreasing and masking Air-blow areas to be repair-painted and also the vicinity thereof, carry out
degreasing with a silicone remover, and then carry out masking as
necessary.
3. Applying an intermediate
coat
If the substrate (ED) is visible through the baked paint film, apply an
intermediate coat.
• Apply the intermediate coat to a thickness which is sufficient to
adequately hide exposed ED areas. The film thickness should be 15 –
20 µm.
• Wipe away misted areas using thinner.
• Wait 3 to 5 minutes to allow the paint film to set, then force-dry it at 80°C
for 15 minutes.
• After force-drying, allow the paint film to cool down, then wet-rub the
intermediate coat with #600 waterproof sandpaper.
• Using #800 waterproof sandpaper, finish the base painting area (the
outer side of the intermediate coat) by wet-sanding.
* If the substrate (ED) is not exposed, there is no need to apply an
intermediate coat.
