Do these come with clear coat already applied?

No. These arrive as bare carbon fiber. Apply your own clear coat or custom finish to protect the weave from UV exposure and maintain the gloss. A quality automotive clear coat will seal the surface and preserve the carbon look long-term.

Will the carbon fiber yellow or fade over time?

Unprotected carbon fiber can yellow under direct UV exposure. Clear coat or a UV-protective topcoat prevents this. Once sealed, the weave stays vibrant and resists oxidation. Plan to apply finish before installation to protect all edges.

How do I seal the cut edges where the splitters meet the rocker?

Sand and prep the mounting surfaces on your rocker line before bolting the splitters in place. Once fitted, apply clear coat or edge sealant to any exposed carbon edges at the seams to prevent moisture ingress. This step protects both the carbon and your paint.
