Should I apply clear coat to protect the carbon finish?

Yes. Clear coat adds UV protection and keeps the weave from dulling over time. Sand the panels lightly and apply your preferred automotive clear in thin, even coats. This is standard practice for exposed carbon and extends the finish life significantly.

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

After fitting, inspect all edge gaps. Tape the perimeter with painter's tape, then apply a flexible urethane or silicone trim sealant along any visible seams. This prevents water intrusion and keeps debris out of the rocker cavity. Remove tape while sealant is still tacky for a clean line.

Will carbon fiber yellow or fade without care?

Carbon itself is stable, but the resin matrix is vulnerable to UV without protection. A quality clear coat acts as a barrier and keeps the weave looking fresh. Wash periodically and reapply clear coat every 2–3 years in high-sun climates for best results.
