Does this carbon fiber come with clear coat protection?

No — these ship in raw carbon. Sand and prep the surface, then apply your chosen clear coat to seal the weave and protect against UV yellowing. A quality automotive clear coat will lock in the finish and keep the weave looking fresh long-term.

How do I seal the edges where the skirt meets the body?

Once mounted, use automotive trim sealant along the edges where the carbon meets the painted body. This prevents moisture and road debris from creeping underneath and keeps the installation clean and weatherproof. Standard body shop sealant works well for this application.

Will these work with factory rockers still in place, or do I need to remove them?

Confirm fitment against your vehicle's existing rocker geometry before drilling or mounting. Reference your vehicle's OEM rocker hole locations and panel edges to determine if the factory rockers need removal or if these install over top. A reference photo of your current setup will help clarify the install path.
