New glass coating spray. 2 pieces. Easy, simple 9H spray-type glass coating agent. Since it is a liquid spray, it can be easily applied without the inclusion of air bubbles or dust. It can be applied in multiple layers, on top of protective films, and directly onto screens that are already scratched. Hardness reaches 9H equivalent after approximately 1 hour of drying. The effect lasts for up to 1 year, but there are individual differences as the effect diminishes with daily use. Each bottle contains enough for approximately 4 smartphone screens.
