With a sudden drop in temperature and facing cold weather, some car owners may have the following question: Are you afraid of the cold when parking outside in winter? Is there any damage to the car paint? However, some car owners hold a different opinion: car paint is not afraid of freezing, but more afraid of exposure to summer sun. So is car paint afraid of the cold or the heat?
The conclusion is that car paint is afraid of both cold and heat.
The fear of cold in car paint is mainly manifested in the following aspects.
1.Not cleaning snowflakes can corrode car paint
Snowflakes may seem pure and pure, but they contain a large amount of corrosive substances such as acid, alkaline, or salt. If the snow covering the car is not removed in a timely manner, the car paint will be corroded by corrosive components in the snow. Over time, it may rust the car paint, causing the external gloss to lose its luster, and in severe cases, the car paint may peel off.
2.Snow melting agents have a strong erosive effect
Snow falling on the car paint will melt into water, and the accumulated snow will cause the bottom layer of water to condense into an ice layer. When the ice layer on the car paint is difficult to remove, a snow melting agent needs to be used.
At present, the main deicing agents on the market are chloride salt deicing agents (sodium chloride, calcium chloride, magnesium chloride, potassium chloride, etc.), commonly known as "ice salts". Mainly using snow melting materials to reduce the freezing temperature of water, melting new snow during snowfall, and preventing snow from freezing. Chlorides, sodium, calcium, magnesium, potassium, and other metal compounds all have a strong corrosive effect on automotive paint.
3.Low temperature makes car paint "brittle"
Low temperature environments in winter can make car paint more brittle and more prone to cracking after being hit.
On the other hand, stones and ice on the roadside are not the same. They are actually harder in low-temperature environments. Therefore, when driving in low temperatures in winter, stones and ice on the roadside are more likely to damage the car paint. Even small stones can damage the car paint and produce cracks during high-speed movement.
The fear of heat in car paint is manifested in the following aspects.
1.UV exposure exacerbates paint aging
Under strong sunlight, high temperatures and ultraviolet rays can cause excessive and rapid oil separation on the paint surface, resulting in a decrease in brightness and color of the paint. If exposed for a long time, the paint surface will form an oxide film, the service life will also be shortened, and excessive oil loss on the paint surface may lead to paint cracking.
2.High temperature rainwater, expanding paint damage
In the summer when it rains frequently, acid rain is also a major challenge for car paint. Acid rain contains acidic substances and has strong corrosion. Mild cases can cause discoloration of the car paint, while severe cases can directly leave spots, pits, peeling, and peeling on the surface of the car paint. In addition, high temperature and humid environments can also cause paint damage to continue to expand.
3.Parking under trees can easily get stuck with tree glue and bird droppings
To avoid high temperatures, car owners often choose to park in a shaded area. For car owners without a garage, under a tree is the best choice, but it is difficult to escape attacks from tree gum and bird droppings.
These types of things are generally highly acidic and not only stick to car paint, making it difficult to clean, but also have strong corrosiveness and permeability. If not treated in a timely and appropriate manner, they can cause permanent corrosion to the car paint in severe cases.
How to maintain winter car paint?
1.Try to park the car indoors and avoid strong sunlight during parking to reduce rain exposure.
2.Do not wash the car immediately when it is still hot. After being exposed to scorching sun or when the engine has just stopped running, cleaning with cold water can cause rapid cooling, which is not conducive to surface paint, and it is not advisable to directly wash the engine.
3.Do not use a dry towel to wipe the dust. Do not dry wipe the car, the small gravel on it may wear the paint surface, so be sure to rinse it with water.
4.Special corrosive substances should be cleaned immediately, such as fallen leaves, resin, bird droppings, and other dirt on the vehicle body, which must be cleaned in a timely manner to avoid corroding the paint surface.
5.Wash the car promptly after rain. Rainwater also has a corrosive effect on the car body, so it is necessary to wash the car in a timely manner after rain.
Of course, the most worry free and effortless way is to stick an paint protection film! Not only can it isolate external corrosion, but it can also self repair small scratches. Wearing car clothes can also avoid wash marks, sun marks, and create a shiny new car paint.
