How to locate vehicle paint color code?

The paint color code of a vehicle can be found on the Compliance / Manufacturer’s / Identification Plate which can be located in various positions of a vehicle depending on manufacturer. The most common location would be on the driver side door jamb. Other places to check are under the hood, inside the glove box, the trunk or on the vehicle's original window sticker. For more information and examples of manufacturers Identification plates, click here.

How to apply touch-up paint on vehicle?

1. Prepare the area

  • Thoroughly wash the car and the specific area you're repairing to remove any dirt, wax, or grease.
  • Ensure the surface is completely dry.

2. Apply primer (if needed)

  • If the scratch has gone down to bare metal, apply a thin layer of primer.
  • Allow the primer to dry completely according to the manufacturer's instructions.

3(A). Apply the basecoat

  • Shake the touch-up paint well to ensure it's thoroughly mixed.
  • Use a minimal amount of paint. For a scratch, try to dab the paint into the chip rather than brushing it on like a stroke.
  • Apply the paint in thin, light coats, as using too much can look clumpy.
  • Let each layer dry for 15-20 minutes before applying the next, if needed.

3(B). Apply the midcoat

  • If your vehicle's paint has a pearl layer, you'll need to apply the midcoat after the basecoat is dry. Follow the same process as with the basecoat, applying thin layers and allowing each layer to dry.
  • Apply necessary coats to achieve desired color match.

4. Apply the clearcoat

  • Once the final color coat is dry, apply a thin, even layer of clearcoat to protect the repaired area.
  • Let the clearcoat dry completely.

5. Finish and blend the repair

  • For a smoother finish, once the clearcoat is fully dry and the paint has cured, wet sand the repaired area with very-fine grit sandpaper (ie. 2000 to 3000 grit).
  • After sanding, use automotive rubbing compound or polishing compound to buff the area and restore the shine.
  • Apply a coat of wax to the repaired area after it has fully cured to protect the paint and provide a uniform appearance.
