High spots in ceramic coatings are uneven areas where excess product has cured, resulting in visible streaks or patches that detract from the vehicle’s finish. These imperfections often appear as darker patches or rainbow-like streaks on the paint, especially under proper lighting conditions. ​

Key Takeaways:

• High spots occur due to uneven application or inadequate leveling of the ceramic coating.​
• Proper lighting and inspection techniques are essential to identify high spots early.
• Timely correction methods, such as buffing or polishing, can effectively remove high spots.

Identifying High Spots

High spots are typically darker patches or rainbow-like streaks on your vehicle’s paint. They may also appear as smudges or streaks that differ from the surrounding areas. Proper lighting is crucial for detection; using a swirl finder light can help reveal high spots, especially on vertical panels. On lighter-colored vehicles, high spots can be more challenging to detect and may require additional lighting or inspection under cloudy skies.

Preventing High Spots

Prevention is key to avoiding high spots in ceramic coatings. Here are some best practices:​

• Apply Evenly: Use straight, even lines during application to ensure consistent coverage.
• Work in Small Sections: Focusing on manageable areas allows for better control and reduces the chance of missed spots.​
• Use Proper Lighting: Adequate lighting during application and inspection helps in identifying and correcting high spots before they cure.​

Correcting High Spots

If high spots are detected, prompt action is necessary to correct them:​

• Immediate Reapplication: For recently applied coatings, reapplying a small amount of the coating over the high spot and buffing immediately can remove the imperfection.
• Buffing: Gently buffing the high spot with a soft microfiber cloth can help level the coating if addressed promptly.​
• Polishing: If the coating has cured, lightly polishing the affected area with a mild abrasive polish and a soft foam pad may be necessary, followed by reapplication of the coating.

Conclusion

High spots in ceramic coatings can mar the appearance of your vehicle but are preventable and correctable with proper techniques. By ensuring even application, working in small sections, and utilizing appropriate lighting, you can minimize the occurrence of high spots. Timely identification and correction methods, such as buffing or polishing, can restore the flawless finish of your vehicle’s ceramic coating.
