Durability: Less exposed to car wash brushes and wind drag. Easy Install: Uses tension and automotive-grade tape inside the channel (no drilling). Pro Installation Tip: For the perfect fit, clean the window track with rubbing alcohol first. After sliding the visors into place, roll the windows up slowly and leave them closed for at least 48 hours. This "sets" the visor into the weatherstripping for noise-free operation.
