Will the carbon fiber pattern fade or yellow in sunlight?

The printed pattern is protected by a clear coat layer, but long-term UV exposure will eventually dull any black finish over years of direct sun. Keeping your truck garaged or under cover slows this process significantly.

Do these visors come ready to install, or do I need to prep them first?

These arrive ready to fit — no sanding, priming, or painting required. Test-fit all four pieces before committing to your mounting method.

What's the best way to seal the edges where the visors meet the window frame?

Edge sealing depends on your install method — if you're using adhesive, apply it along the mounting surface before positioning. If using mechanical fasteners, gaps will be minimal. A small bead of black silicone caulk along the top edge after install keeps water out without being visible.
