In the car wash machine, in addition to washing with water and washing with shampoo“Wax” “Water repellent” “Glass coat”You may be able to select a menu such as. Basically all these courses,Course to apply coating after car washis.

Wax coating

Wax coating will be a popular method for car wash machines.

If you select a course such as “Wax car wash” from the car wash menu, the body will be washed with shampoo and then wax will be applied to the surface of the body.

Similar to commercially available wax liquids, after washing the car, an “oil film” is formed on the body surface to prevent dirt. It will keep your car clean, avoiding dirt from rain and mud.

Depending on the shop where the car wash machine is installed (gas station, car wash, etc.), you can choose the menu from about 500 yen each time.

Of the three types introduced here, it is recommended for those who want to coat a car with a small budget.

Water repellent coating

Water repellent coating is a higher rank than wax coating and is a method with higher water repellency.

There are cases where the names and ingredients such as “foam blow” and “polymer coat” differ depending on the store where the car wash machine is installed. After performing normal car washing work, a coating agent containing silicone resin is applied to the body surface. The coating creates a protective coating.

The film that is made is said to be stronger than the components of the wax coating, and has the advantage of being less likely to stain the body for a long period of time.

The water-repellent coating depends on the shop where the car wash machine is installed, but it seems that there are many cases where you can choose the menu from about 1000 yen each time.

If you have a budget and want a longer-term effect than wax coating, we recommend water-repellent coating.

Glass coating

Glass coating is an advanced method over water repellent coating. In the menu set for the car wash, the case shown at the top stands out.

Notations such as “glass”, “prism”, and “premium” are used to enhance the durability of the coating and the gloss of the coating. After washing the car, a coating agent containing glass-based components is sprayed onto the body to form a film on the surface.

In the type explained this time, it seems that there are many cases where you can use it from about 2000 yen at a time with a high price setting in the menu of the car wash machine.

It is recommended for people who want to not only prevent the body surface from getting dirty but also maintain a glossy state, and those who are in special cars such as luxury cars and sports cars.

If the wax adheres to the glass part, it cannot be removed with car shampoo.Be careful with sunroof cars.

In addition, if the coating agent adheres to the windshield, it may cause cloudiness, the wiper to get caught, or chattering, which may interfere with driving on a rainy day.
