This makes the car more planted on the road, providing better handling and control at high speeds, especially in performance-oriented driving situations.

UV and Weather Resistant Finish: The carbon fiber is coated with a UV-resistant clear coat that protects the material from fading, yellowing, and sun damage. The finish also offers resistance to weather elements, keeping the diffuser looking sleek and glossy for years.

Regular Cleaning: Maintain carbon fiber parts by cleaning them regularly with a soft cloth and a mixture of mild soap and water. Avoid abrasive or harsh cleaners that could harm the finish.
Use Microfiber Pads and Cloths: Opt for microfiber pads and cloths when cleaning or applying protective coatings to prevent surface scratches.
Protect from Sun and Chemicals: Limit exposure to direct sunlight and harsh chemicals, as they can damage carbon fiber. When possible, use protective covers or park your vehicle in shaded areas.
