Addressing Common Issues Post-Application

Introduction

Ceramic coatings offer exceptional protection for your vehicle's paint, but they aren't entirely foolproof. Even with proper application, issues can arise that may affect the appearance and performance of your coating. This guide addresses the most common post-application problems and provides practical solutions to resolve them.

High Spots and Streaking

The Issue

High spots occur when excess coating isn't properly removed during the leveling process. They appear as streaks, smears, or rainbow-like discolorations on the surface.

Causes

• Insufficient buffing after application
• Applying too much product
• Working in conditions that are too hot or cold
• Allowing the coating to cure too long before leveling

Solution

For Fresh Installations (Within 24-48 Hours):

1. Apply a small amount of the same ceramic coating to the affected area
2. This will reactivate the high spot
3. Immediately buff with a clean microfiber towel using firm pressure
4. Inspect under different lighting to ensure complete removal

For Cured Installations:

1. Use a light polish with a finishing pad on a dual-action polisher
2. Work at low speed (speed 3-4 on most polishers)
3. Focus only on the affected area to minimize impact on the coating
4. After polishing, clean with an IPA solution and reapply coating if necessary

Water Spotting

The Issue

Water spots appear as white, circular marks on the coated surface, often containing mineral deposits.

Causes

• Hard water drying on the surface
• Washing in direct sunlight
• Inadequate drying after washing
• Chemical contamination in water

Solution

For Light Water Spots:

1. Mix a 50/50 solution of distilled white vinegar and distilled water
2. Spray onto affected areas and let sit for 1-2 minutes
3. Wipe clean with a microfiber towel
4. Rinse thoroughly with clean water and dry immediately

For Stubborn Water Spots:

1. Use a dedicated water spot remover formulated to be safe for ceramic coatings
2. Apply according to manufacturer instructions
3. For persistent spots, a light polish may be necessary (same technique as fixing high spots)

Hazing or Cloudy Appearance

The Issue

The coating appears hazy, cloudy, or has a milky appearance rather than the expected glossy finish.

Causes

• Application in high humidity environments
• Contamination before or during application
• Improper surface preparation
• Product incompatibility with previous treatments

Solution

1. First attempt an IPA (Isopropyl Alcohol) wipedown:

   • Mix 50% IPA with 50% distilled water
   • Apply to a microfiber towel and wipe the affected area
   • This may remove light hazing from residual product

2. If hazing persists:

   • Use a fine polish with a soft foam pad
   • Work at low speed with light pressure
   • After polishing, clean thoroughly and assess if reapplication is needed

Reduced Hydrophobic Properties

The Issue

The coating no longer repels water as effectively as when first applied.

Causes

• Surface contamination buildup
• Chemical damage from harsh car wash soaps or cleaners
• Environmental fallout (industrial fallout, rail dust, etc.)
• Natural degradation over time

Solution

1. Decontamination wash:

   • Use an iron remover to address metal contaminants
   • Follow with a clay bar treatment
   • Wash with a pH-neutral shampoo specifically for coated vehicles

2. Apply a ceramic boost spray:

   • These products are designed to refresh the hydrophobic properties
   • Apply every 3-6 months for optimal performance
   • Follow product instructions carefully

Swirl Marks and Light Scratches

The Issue

Fine swirl marks or light scratches appear on the coated surface.

Causes

• Improper washing technique (using circular motions or abrasive materials)
• Automatic car washes with brushes
• Dust wiping with dry towels
• Abrasive polishing compounds

Solution

1. For light swirls:

   • Use a ceramic-safe polish or pre-wax cleaner
   • Apply with a soft foam finishing pad
   • Work in straight overlapping lines at low speed

2. Prevention is key:

   • Always use the two-bucket wash method
   • Wash with high-quality microfiber wash mitts
   • Use grit guards in your buckets
   • Dry with plush microfiber towels using light pressure

Peeling or Flaking

The Issue

The coating appears to be peeling or flaking off the surface.

Causes

• Inadequate surface preparation before application
• Contamination between paint and coating
• Application over non-compatible products
• Manufacturing defect in the coating

Solution

This is unfortunately one of the most serious issues and typically requires complete removal and reapplication:

1. Remove the failing coating:

   • Follow proper coating removal procedures (see our guide on coating removal)
   • Ensure complete removal of all residues

2. Properly prepare the surface:

   • Clay bar the entire vehicle
   • Polish to create a perfectly clean surface
   • Perform multiple IPA wipedowns

3. Reapply the coating following manufacturer instructions meticulously

Maintenance Tips to Prevent Issues

• Wash your vehicle every 2 weeks with pH-neutral shampoo
• Avoid automatic car washes with brushes
• Don't wash in direct sunlight
• Use ceramic-specific maintenance sprays quarterly
• Address bird droppings, tree sap, and bug splatter immediately
• Avoid parking under trees when possible

When to Seek Professional Help

If you've attempted the solutions above without success, it may be time to consult a professional detailer who specializes in ceramic coatings. They have access to professional-grade products and equipment that can address more severe issues without compromising your vehicle's paint.

Conclusion

Most post-application issues with ceramic coatings can be resolved with proper techniques and products. The key is addressing problems quickly before they worsen. With proper maintenance and care, your ceramic coating can provide years of protection and gloss for your vehicle's finish.
