[McIsabela]

It is normal for the production dates of new car glass to be different. Car glass is produced on assembly lines, and different batches of glass will have different production dates. Car glass is imprinted with letters, numbers, and patterns, representing the car manufacturer, glass brand, production date, and China's 3C mandatory certification mark. The functions of car glass are: 1. To shield from wind and rain, and to provide sound insulation and noise reduction; 2. To reduce wind resistance and guide airflow; 3. To protect the safety of passengers. The maintenance methods for car glass are: 1. Use dedicated or suitable wiper blades and replace them promptly; 2. Keep the windshield clean; 3. Use automotive-specific glass cleaner.
