Do I need to apply clear coat to protect the carbon fiber?

Yes — applying a UV-protective clear coat is the best way to preserve the finish and prevent yellowing from sun exposure. Carbon fiber exposed to UV without protection can fade over time. A quality clear coat seals the weave and keeps your finish looking sharp for years.

Should I seal the edge where the trunk meets the body?

Sealing the exposed edge is a good practice to keep moisture out of the weave and prevent any edge delamination. Use flexible automotive sealant or edge trim around the perimeter where the trunk interfaces with the body. This keeps water out and extends the life of the panel.

What prep work do I need to do before painting or clear-coating?

Sand the surface to create a smooth profile for adhesion, then wipe down with a tack cloth to remove dust. Use appropriate sandpaper grit for your chosen finish, then apply your paint or clear coat per manufacturer instructions. Proper prep is the difference between a flawless finish and one that won't stick.
