The Professional Auto Drying Water Blade is a heavy duty blade that is designed to remove water from glass and painted surfaces with a simple swipe. This blade is constructed from a unique rubber material which conforms to the body of the car and pulls off the water in one direction. The handle is built from heavy duty molded plastic for years of use. The blade measures a full 12 inches for quicker drying times. The length makes it a great tool to dry trucks, vans, RVs and boats. The water blade glides gently over the paint to swipe water leaving a streak free shine with no spots. This blade also works great on glass.
