Just move it around and use it on glass water repellent vehicles.
By wiping the wiper for about 3 minutes on the dry glass surface, the water repellent ingredients kneaded into the silicone rubber seep and form a water-repellent membrane, which effectively repels water droplets. In addition, the wiper movement has been given a water repellent effect, so it will always maintain a stable water repellent effect without peeling off the water repellent coating on your vehicle.
