I m av-kool is written on the glass of many cars. What does this mean?

This golden "I am Weigu" is called "Guan Wei Safety Standard". A car pasted with Wei film will put such an exquisite small sign on the window to confirm that the owner chooses Guan Wei film and enjoys the excellent quality of Guan Wei products.

Generally, vehicles equipped with VIGA will also put a big "I am V-Kool" safety sign on the rear windshield at the same time. This big safety sign is not only a status symbol, but also has a real safety function. At night, when the car lights hit this sign, they will reflect bright light, warning the rear car owners to keep the distance, which will bring safety to driving, especially at night.

This is the exclusive safety logo of the insulation film brand "Gu Wei" that many high-end car owners will choose, and V-KOOL is the English name LOGO of this brand.
