Used of glass guard:-

The glass guard works at the nanoscale level. Once applied, the product fills the microscopic pores in the glass or other surface and permanently bonds in place leaving a smooth, protective coating that can last indefinitely with proper maintenance and the occasional use of our specially formulated after-care cleaner. They are a great way to prevent the spread of germs from one person to the other, which ultimately helps slow down a virus-like COVID-19.
