Features: The low-profile aerodynamic form suppresses wiper lift-off even at high speeds, achieving stable wiping performance. Water-repellent effect: Uses silicone rubber with PIAA's unique silicone oil, forming a water-repellent film and repelling rain just by operating the wipers for 5 minutes. Compatibility: Can also be used on glass with water-repellent coatings. Thank you for viewing. I purchased this but didn't use it, so I am putting it up for sale.
