6. Do new cars need coating?

Many new car owners have this question: Do new cars need coating?: Yes. This is because new cars are usually simply coated with car wax after leaving the factory, without thorough paint care. To clarify this issue, we must first understand the reasons why cars become old.

Cars will become old after a certain period of use. This is the result of the "oxidation" of the paint itself. We have found out the causes and countermeasures that cause car paint to oxidize and share them with everyone. 

The main factors that cause car paint to become old are the following:

1: Reasons for the car paint itself: 
① The main components of the car paint include a large amount of resin, petroleum grease, metal and other elements, and the chemical properties of these components determine that they are easily oxidized and deteriorated, which makes the car paint itself also Has easy oxidation. 
②Car paint structure The paint surface is composed of multiple layers of overlapping paint sprays. Each layer has countless pores. The multi-layer overlapping surface effectively prevents moisture from corroding the metal parts, but the surface of the paint surface is still there. There are pores, so various substances will inevitably enter the pores to accelerate the oxidation of the paint surface.

2: External reasons: 
The oxidation of car paint itself is a slow process, but many external factors will accelerate its oxidation process, such as sunlight (ultraviolet light), dust (mainly iron powder), friction and collision, bird droppings and insect droppings, etc. Acid rain, scale, gum, air conditioning water, oil fumes, flying paint, improper care, etc.

As a car is used for a long time, the paint will become old. The lack of glossy paint is an important sign that a car is getting old. Oxidation is the main reason why car paint becomes old. Because the main components of car paint and metals, these substances determine that car paint is susceptible to oxidation. Especially in harsh environments such as excessive ultraviolet rays and acid rain, car paint is more likely to oxidize and become old.
