Do I need to apply clear coat, or does this come sealed?

These ship as raw carbon fiber. Apply a UV-protective clear coat after final fitting to lock in color and prevent oxidation. A quality automotive clear coat also hardens the surface and makes cleaning easier long-term.

How do I seal the edges where the over fender meets the door or original panel?

Sand and dry-fit the edges first to confirm gap consistency. Once you're happy with fitment, seal the perimeter with automotive-grade trim sealant or self-adhesive weatherstripping before final fastening. This prevents water and debris from creeping into the gap.

Will the carbon weave pattern yellow or fade in the sun?

Bare carbon fiber is vulnerable to UV without protection. A clear coat acts as a UV shield and keeps the twill weave looking crisp. Reapply clear coat every 2–3 years depending on sun exposure and climate for best appearance.
