Why Dry Carbon Develops White Cracks & How to Prevent It

Dry carbon fiber is a premium motorsport material, but did you know it’s highly vulnerable to UV damage? If left unprotected, it can develop white cracks, hazing, and surface fading. In this guide, we explain why this happens and how to protect your investment.

🔹 Why Do White Cracks Appear on Dry Carbon?

Unlike wet carbon fiber, dry carbon does not have a protective gel coat. This makes it extremely sensitive to UV rays, leading to:

• ☀️ UV Damage: Prolonged sun exposure degrades the resin, causing cracks.
• 🌧️ Resin Oxidation: The carbon fibers weaken over time when exposed to air and moisture.
• 🔍 Microfractures: Heat cycles and environmental stress create small cracks that grow over time.

🔹 How to Prevent White Cracks on Dry Carbon

To keep your dry carbon parts looking brand new, follow these essential steps:

• ✔️ Apply a UV-resistant clear coat – This creates a protective barrier against sun exposure.
• ✔️ Use a ceramic coating – Adds an extra layer of UV and chemical resistance.
• ✔️ Avoid prolonged sun exposure – Park in shaded areas or use a car cover.
• ✔️ Regular maintenance – Clean with non-abrasive products to preserve the surface.

🔹 What If My Dry Carbon Already Has White Cracks?

Once white cracks appear, they cannot be fully reversed, but you can minimize their visibility by:

• 🛠️ Polishing the surface with specialized carbon fiber restorers.
• 🔄 Reapplying a UV-resistant clear coat to slow down further damage.
• 🔧 Professional refinishing for severe cases.

📌 Conclusion: Protect Your Carbon Fiber Investment

Dry carbon fiber is a high-performance material, but **it requires proper care** to maintain its look and durability. **Applying a UV-resistant clear coat or ceramic coating is a must!**
