Will the carbon fiber pattern fade or yellow in the sun?

The textured carbon finish is UV-resistant by design. Hard panel construction holds color well, but like any exterior piece, prolonged direct sunlight will eventually age the finish. Parking in shade when possible extends the lifespan.

Do I need to seal the edges where these mount?

Installation method and edge sealing requirements aren't specified in the product data. Test-fit before committing to any adhesive or fasteners. If gaps appear, weatherstripping tape can seal edges to prevent water entry.

Can I clean these with regular car wash products?

Yes. Treat them like any painted plastic trim—mild soap, water, and a soft cloth work fine. Avoid harsh solvents or abrasive scrubbing that could scratch the carbon pattern finish.
