2. Identifying Your Car's Paint Code
Before using the touch up paint pen, it is crucial to confirm your vehicle's paint code to ensure an exact match. The Carhoo pen is specifically formulated for Toyota vehicles with paint code 1F9 Slate Metallic.
2.1 Locating the Paint Code
For Toyota cars, the paint code is typically found on the vehicle's identification plate or sticker. Common locations include:
- The driver's side door jamb.
- The passenger's side door jamb.
- Under the hood, often on the firewall or strut tower.
The paint code is usually a combination of numbers and letters, such as '1F9'.

2.2 Verifying the Color Match
Upon receiving the touch up paint pen, compare the original paint label on the pen's cap with your car's body color in natural light. This step helps confirm that there is no noticeable color difference before application. If the color does not appear to match, contact Carhoo customer service for assistance.
3. Application Instructions
Follow these steps carefully for optimal scratch repair results.
3.1 Preparation
- Clean the Area: Thoroughly clean the scratched area with soap and water to remove dirt, wax, and grease. Dry the area completely with a clean towel.
- Sand (Optional, for deeper scratches): For deeper scratches or rough edges, use the included 1000# or 2000# sandpaper to gently smooth the surface. Clean and dry again after sanding.

3.2 Priming the Pen
- Shake the Pen: Shake the touch up paint pen vigorously for approximately 15 seconds to ensure the paint is thoroughly mixed.
- Prime the Tip: Remove the cap. Press the pen tip vertically onto a piece of horizontal cardboard or a test surface about 30 times until the paint flows freely and evenly. This primes the tip and ensures smooth paint discharge.
3.3 Applying the Paint
- Initial Application: When repairing, hold the pen at a 45-degree angle. Apply the paint slowly and evenly from left to right, filling the scratch.
- Multiple Layers (if needed): For deeper scratches, apply 1-3 thin layers, allowing each layer to dry for at least 30 minutes before applying the next. Avoid applying thick layers, as this can lead to uneven drying and poor adhesion.
- Using the Outlining Pen: For very fine scratches, the included outlining pen can be used for precise application.

3.4 Post-Application
Allow the repaired area to dry completely. For best results, avoid washing or waxing the repaired area for at least one hour after application. The fast-drying formula ensures durability against UV rays, rain, and corrosion.
4. Maintenance and Storage
Proper care and storage will extend the life of your Carhoo Touch Up Paint Pen.
- Cleaning the Tip: After each use, wipe the pen tip clean with a paper towel to absorb any remaining paint. This prevents clogging and ensures smooth flow for future use.
- Recap Securely: Always replace the cap firmly after use to prevent the paint from drying out. The pen features a secondary airtight lid for double layer protection.
- Storage: Store the pen in a cool, dry place away from direct sunlight. An unopened pen can be kept for up to 5 years. Once opened, it can be reused within 1 year.

5. Troubleshooting
- Paint Not Flowing: If paint does not flow, ensure the pen has been shaken thoroughly and the tip has been adequately primed by pressing it repeatedly on a test surface.
- Color Mismatch: If the applied paint color does not match your vehicle, stop application immediately. Contact Carhoo customer service for support. Do not continue using the product if there is a significant color difference to avoid secondary damage to the original paint.
