Do these need clear coat protection?

Yes. Real carbon fiber benefits from clear coat to protect the weave from UV exposure and maintain gloss over time. Apply your chosen automotive clear coat after surface prep — this ensures consistent finish and long-term color stability.

How do I seal the edges where the two pieces meet?

Sand the mating edges smooth, then apply epoxy or carbon-specific adhesive along the joint before final installation. Once cured, you can seal the seam with matching clear coat or body filler if a seamless appearance is your goal. Test fit first to confirm alignment.

Will the carbon weave stay visible, or will paint cover it?

If you paint these, the weave will be covered. Clear coat applications preserve the visible twill pattern and showcase the carbon. For body-color matching, sand and prep the surface, apply primer, then paint — the texture will remain under the topcoat but weave definition will fade.
