Rain-X began in 1972 and was acquired by Pence Pennzoil in 1997, which was also considered to be merged into Shell because Pence is a subsidiary of Shell, and was acquired by Illinois Tools in 2012. For more than 40 years, Rain-X has been developing products for car owners in response to bad weather, and its water displacement coating technology and wiper products are very good, and the wiper products are ranked second in the ranking.

 

There are also many varieties of rainproof agents in Rain-X, and the original glass water repellent spray is more recommended, which has many sales channels and has a good water displacement effect, and the water droplets at a speed of more than 45 kilometers per hour have begun to slide away, and there will not be too many small water droplets on the glass during light rain. Compared with other waterproofing agents, Rain-X has a thinner coating, so the chance of scratching is relatively small, and even if there is noise, it is relatively slight and does not shake very much. Because the coating of Rain-X is relatively thin and the service life is relatively short, a bottle of Rain-X waterproof spray is about 500 ml, and the number of uses is more, and the unit price of more than 100 yuan is slightly more cost-effective.
