Since it is a pure glass product, it has an eco-friendly mirror finish that gives it a glossy finish, and is semi-permanently effective with reliable work during construction. In addition, the construction is relatively easy, the car is not scratched, and there are few construction failures, so there are no complaints from customers. The water-repellent effect is guaranteed for 5 years, and it has a gloss-restoring effect, so even if you wash the car with a car wash machine, the glass coating will not come off. It can also be used for wheels (aluminum) and resins / plastics (bumpers, etc.).
