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

Clear coat is highly recommended. It protects the carbon fiber from UV exposure and environmental contaminants, maintaining the silk finish and preventing surface degradation over time. Sand and prep the surface before applying your chosen clear coat product.

Should I seal the edges where the two pieces meet?

Yes. Edge sealing prevents moisture from infiltrating the carbon fiber layers at the seams. After installation, apply an appropriate epoxy or edge sealant to both the top and bottom edges of the skirt panels where they interface with your vehicle. This extends panel longevity and prevents delamination.

Will the silk finish yellow or fade without protection?

Carbon fiber without UV-protective coating will eventually yellow and dull from sun exposure. Applying clear coat immediately after prep and installation protects the silk finish and maintains its color stability. Avoid prolonged uncovered storage in direct sunlight before installation.
