Oil film removal
Oil film refers to water stain, grease, pollutant and coating residues that cannot be removed with water or glass cleaner.
Why does oil film need to be removed?
It interrupts driving by obstructing the view. In particular, as water and oil film get stuck with each other in rainy days, it is hard to wipe out such foreign matter and have a clear view, hence leading to higher accident risk.

30% improvement in oil film removal due to dual particles!

Rain Repellent Coating
Rain Repellent Coating simply means resistant to penetration by water
Why is Rain repellent coating required?
The glass surface with rain repellent coating changes the rainwater into water drops to reduce the surface area of the rainwater to increase the visibility and to remove the rainwater more easily. Rain Repellent Coating is useful not only in rainy days, but also in snowy days.
