Should I apply clear coat over the carbon fiber?

Yes. Clear coat protects the carbon weave from UV exposure and road contamination. Sand and prep the surface with appropriate grit before applying your chosen automotive clear coat to maintain the factory finish and prevent yellowing over time.

How do I seal the edges where the splitter meets the bumper?

After installation, inspect the edges where the splitter contacts the bumper skin. Use automotive-grade edge sealant or trim tape to close any gaps and prevent moisture and debris from entering. This also gives the joint a cleaner, more finished appearance.

Will this splitter last in daily driving with road salt and debris?

Carbon fiber is durable when properly sealed and maintained. A clear coat layer and regular washing protect against salt and UV damage. Inspect mounting points seasonally and reapply sealant as needed to keep the splitter in top condition.
