Should I apply a UV-protective clear coat?

Yes. Carbon fiber without clear coat will fade and yellow under sun exposure over time. A quality automotive clear coat protects the weave and maintains color depth. Sand the surface with fine grit before applying your finish.

How should I seal the edges where the pieces meet?

The seams between the three pieces can be reinforced with epoxy or resin along the back side before installation. Once mounted, ensure gaps are tight and minimal. Seal exposed edge areas with clear coat to prevent moisture infiltration.

Do I need to prep the carbon surface before painting?

Yes. Sand the entire piece to remove any mold release agent or manufacturing residue, then wipe clean. This ensures primer and paint adhere properly. A clean, prepped surface is essential for a professional finish.
