Do I need to apply clear coat after installation?

Yes. While carbon fiber won't rust, UV exposure will dull the finish over time without protection. A quality clear coat—applied after final prep and fitting—locks in the weave detail and keeps the panels looking fresh for years.

How do I seal the edges where the carbon meets the door and rocker panel?

After fitting, sand the edges smooth, then use edge sealer or clear coat around all perimeter gaps. This prevents moisture creep and keeps the weave from lifting. Your paint supplier can recommend a compatible edge product for your chosen top coat.

Will these yellow without UV protection?

Carbon fiber under bare exposure can take on a yellowish tint as UV breaks down the resin. A protective clear coat applied during prep stops this entirely. Once sealed, the carbon maintains its color and gloss indefinitely.
