Outdoor travelers often wear sunscreen because excessive ultraviolet radiation can damage the skin and cause skin aging, redness, melanin precipitation, etc. Similarly, vehicles under the hot sun should also pay attention to sunscreen, so as to avoid serious oxidation, loss of luster, gradual color deviation and cracking of resins, metal particles and organic solvents in the paint after years of ultraviolet radiation, which will affect the image and value preservation rate of the vehicle.
The chemical components of automobile paint include film-forming substances (resins), pigments (including metal or mica particles), organic solvents and additives. These components will gradually oxidize under the irradiation of ultraviolet light, resulting in color deviation and dry cracking. This is one of the reasons why used cars look impure. Usually, the black paint with poor maintenance tends to be brown and gray, and the white paint tends to be yellow. Therefore, please park your vehicle in the indoor parking lot, building backlight or under the shade of trees to avoid UV damage. It is recommended to wax the car paint once a quarter to prevent water, ultraviolet, static and brighten.
Sometimes, the "gifts" of nature are not what we need. For example, the gum, bird droppings, insect limbs, etc. falling from the sky on the car paint need to be removed in time to avoid corroding the car paint and causing color spots. Among them, bird droppings can overcome hardness with softness, and their destructive power cannot be underestimated. Because bird droppings contain uric acid, the pH range is 3-4, belonging to strong acidity (pH7 is neutral); In addition, it also contains ammonium salt, which will produce electrochemical reaction with the body metal under wet conditions, thus damaging the metal strength.
The physical structure of vehicle paint is usually divided into electrophoresis layer, intermediate coating, paint layer and varnish layer. The main component of the varnish layer is transparent synthetic resin, which can protect the paint layer. After long-term oxidation, the light transmittance will be reduced, resulting in the dim appearance of the vehicle. It is recommended to carry out in-depth maintenance of the paint surface regularly, find professional technicians to use the tools and car paint products certified by the original factory for efficient construction, and provide suggestions on coating or glaze sealing, so as to maintain the lasting brightness of the varnish.
In late summer and early autumn, the ultraviolet ray is strong, the temperature in the car is high, and the interior is easy to be stained with sweat. It is recommended to use a special cleaner to regularly maintain the interior leather, because clean water or soapy water will cause the protein components in the leather to deteriorate and harden, resulting in chapping or discoloration. At the same time, avoid leaving food in the car, so as to prevent the high temperature in the car under the sun from fermenting and producing peculiar smell, which will affect driving comfort.
