Removing fixed windows is a complex and time-consuming procedure, the implementation of which is beyond the capabilities of a mechanic - a car enthusiast. It is difficult to achieve a reliable and waterproof connection between glass and the body without sufficient experience and practice. In addition, this work is associated with the risk of glass damage, which is especially dangerous for laminated windshields, so car owners are strongly recommended to replace fixed glass, especially windshields, by contacting a repair and service station.
