Do I need clear coat on raw carbon fiber?

Yes. Raw carbon fiber is exposed to UV rays and will yellow or fade without protection. A quality automotive clear coat seals the weave and preserves the finish. Apply after any surface prep and sanding.

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

Sand the mating edges smooth and apply a thin bead of epoxy or automotive-grade adhesive before final assembly. Once cured and sealed with clear coat, the joint becomes weatherproof. This step prevents water intrusion at the seam.

Will carbon fiber rockers rust or corrode?

No. Carbon fiber is inert and will not rust. However, check the mounting points and fasteners—use stainless steel hardware to prevent corrosion at attachment areas, especially in salt or wet climates.
