  • A wide field of use: cars, motorcycles, agricultural machinery, rail vehicles, industrial equipment, boats and yachts.

All the products shown on this page can be found in the automotive series catalog of KUDO®.

Repairing metal parts

Shallow scratch: only the clear coat and the paint are damaged, the primer is intact

How to tell: wet the scratch with water; if it becomes invisible, the primer is not damaged.

Selecting the right coating products

Metallic paint. Repair procedure:

  • Degrease the surface with silicone remover KU-9100.
  • If the scratch is small, use the brush to apply car repair lacquer KU-70000.
  • If the damaged area is fairly large, apply to it 1K automotive varnish KU-9010. It is best to clear the entire body panel. If clearing the entire panel is difficult for some reason, the clear coat can be applied to the damaged area only, and the transition zone treated immediately with spot blender KU-9101.

Non-metallic paint. Repair procedure:

  • Degrease the surface with silicone remover KU-9100.
  • If the scratch is small, use the brush to apply automotive repair paint KU-7XXXX in a matching color.
  • If the damaged area is fairly large, apply to it 1K alkyd automotive repair paint KU-4XXX in a matching color. If there is no matching color, have the color matched at a specialist store and use the pre-charged aerosol cans FILL SPRAY KU-9900 or FILL ONE KU-9901. Treat the transition zone immediately with spot blender KU-9101.

Scuff that has gone through the primer, the metal is intact

How to tell: wet the damaged area with water; if it is still visible, the coating is damaged down to the primer.

Selecting the right coating products

Metallic paint. Repair procedure:

  • “Open up” the damage (sand it).
  • Degrease the surface with silicone remover KU-9100.
  • If the scratch is small, use the brush to apply anticorrosion repair primer KU-70006. Let the primer dry, then use the brush to apply automotive repair paint KU-7XXXX in a matching color, and over the paint car repair lacquer KU-70000.
  • If the damaged area is fairly large, apply to it filler primer KU-220X. Once the primer has dried, apply 1K metallic automotive repair paint KU-4XXXX. If there is no matching color, have the color matched at a specialist store and use the pre-charged aerosol cans FILL SPRAY KU-9900 or FILL ONE KU-9901. Once the paint has dried, apply 1K automotive varnish KU-9010. It is best to clear the entire body panel.
