With the rapid development of automotive manufacturing technology, the service life of cars has also been increasing year by year. As cars are driven for longer periods of time, the body of the car is riddled with scars. Faced with a beloved car with good performance but heavily damaged paint, do car owners feel powerless?

These scars, perhaps originating from seemingly insignificant details in our daily lives, have quietly become the biggest "hidden killer" of car paint. Today, let's uncover the true faces of these "culprits" and see if you have also been tricked!

1：The dual impact of high temperature and ultraviolet radiation

The ultraviolet rays in sunlight are the main culprit causing oxidation of car coatings. Under the irradiation of ultraviolet rays, the paint surface of the car gradually forms an oxide film, which becomes darker and less glossy, and the brightness and color depth decrease by several degrees. Long term exposure to sunlight not only causes the car paint to lose its original luster, but also may lead to oil loss, making the car paint fragile and prone to cracking.

2: The erosion of bird droppings, insect carcasses, and tree gum

Bird droppings, insect carcasses, tree gum, and other seemingly harmless natural residues are actually highly acidic. Staying on the surface of car paint for a long time can cause corrosion to the paint. Their corrosiveness is permeable and irreparable, making the originally smooth paint surface bumpy.

3: The chemical attack of acid rain

Acid rain has strong corrosiveness. Acid rain damage can be classified into three categories according to different degrees.
① Slight erosion: The surface of the car paint appears to have no significant impact
② Moderate erosion: The surface of the car paint will age, and even discolor and fade
③ Severe erosion: leaving spots, potholes on the surface of the car paint, or causing the car paint to peel or peel off

4: Traffic film pollution during driving

During driving, vehicles generate static electricity due to air friction, which adsorbs dust, exhaust gas, and oil stains on the paint surface, gradually thickening. Over time, a strong and hard film will form on the surface of the car paint, which is commonly known as the "traffic film". Traffic film not only affects aesthetics, but also corrodes car paint, leading to serious consequences such as discoloration, cracking, and peeling.

5：Sun stripe

There are many reasons for the formation of sun streaks, including improper car washing methods, friction with dust during high-speed driving, and wiping with wax brushes containing fine particles. Under the illumination of sunlight, intricate and small scratches present halos to the eye in circles. Especially in black car paint, the sun pattern is very obvious.

6："Intimate contact" caused by scraping and rubbing

It is inevitable to encounter scratches while driving, even small scratches may damage the car paint. Especially during the rainy season, acid rain poses a greater threat to the paint surface. Due to the acidic content of rainwater, it can corrode the car paint. If the damaged area is not treated for a long time, it will accelerate the erosion of the damaged area and the aging of the paint surface.
And if the scratched area is made of metal steel plate, rust is inevitable. If it is soaked in rainwater for a long time, the corrosion area will increase, thereby increasing maintenance costs and greatly reducing the value of the car.
7：Improper car maintenance and washing methods

Frequent polishing and the use of inferior car washing tools can cause irreversible damage to the car paint. Although polishing can enhance gloss, frequent operation can cause the car paint to become thinner and lose its original protection. When washing a car on your own, the burrs on inferior towels and corrosive detergents can also damage the car paint.

In addition to the seven major culprits mentioned above, daily exposure to wind, sun, rain, sand and gravel can also cause varying degrees of damage to car paint.
Therefore, as car owners, we should always pay attention to the paint condition of our cars and regularly inspect, clean, and maintain them. Once damage to the paint surface is found, it should be promptly repaired to prevent minor problems from escalating into major ones. At the same time, we also need to learn the correct car maintenance, master the correct car washing method, and avoid unnecessary damage to the car paint.
Of course, the best way is to apply Motec PPF to your car, which not only brightens the paint but also automatically repairs minor scratches, providing comprehensive protection for the paint. Taking care of your car is like taking care of flowers. Let's take action together to protect every inch of your car's "skin" and keep it shining in the long river of time
