Is Car Waxing or Crystal Coating Better?

Overall, car crystal coating is better than car waxing. The specific details are as follows: 1. From a process perspective, crystal coating has a more meticulous and strict application process compared to waxing. The waxing process involves cleaning the car thoroughly, then applying wax manually or mechanically, and wiping off the excess wax after 3-5 minutes to complete the process. The crystal coating process, after an initial cleaning, requires claying to remove surface contaminants, removing tar spots, polishing to eliminate oxidation layers and minor scratches, then degreasing to thoroughly remove any residual oils before applying the crystal coating. 2. In terms of effectiveness, crystal coating provides more comprehensive protection for the car's paint. Waxing generally offers brightening and hydrophobic effects and is one of the earliest car care products. Crystal coating, on the other hand, is currently the leading mainstream maintenance product in car care. Besides brightening and hydrophobic effects, crystal coating also provides some scratch resistance and protects against damage from bird droppings, tree sap, and acid rain. High-quality crystal coatings can also offer varying degrees of oil resistance. 3. From a protection duration standpoint, crystal coating lasts longer than waxing. Car wax typically offers protection for about a month and gradually wears off with each car wash, usually disappearing completely after 2-3 washes. Crystal coating, being a nano-level material, adheres better to the car's paint, providing protection that can last 1-2 years.

Why is there no ready stock for the Ora Black Cat?

The production capacity of this car is relatively small, and regardless of the version, all require waiting, with no inventory available nationwide.

What is the tire size of the Kia K4?

The Kia K4 comes with two tire sizes: 205/60R16 and 215/50R17. In 205/60R16, the first number 205 represents the tire width of 205MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, and 16 stands for the rim diameter of 16 inches. The middle letter "R" denotes a radial tire. In 215/50R17, the first number 215 represents the tire width of 215MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 17 stands for the rim diameter of 17 inches. The middle letter "R" denotes a radial tire. The Kia K4 uses Hankook H426 tires, which focus on quietness and comfort. The spare tire is a non-full-size tire. If you want to replace the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car, making sure the jack is positioned under the vehicle and forms a right angle with the ground; Remove the hubcap, loosen the nuts counterclockwise, but do not fully unscrew them—just enough to eliminate resistance. Keeping the tire on the ground when loosening the nuts for the first time ensures that the nuts turn, not the tire; Turn the nuts counterclockwise until they come off, repeat this step for all lug nuts, and fully remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, and tighten them by hand until all nuts are snug. The tire replacement is now complete. Besides the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h; Rim specification: Indicates the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F."

Why does the car key sometimes not respond when pressed?

The specific reasons why the car key sometimes does not respond when pressed are as follows: 1. Nearby interference. Car remote keys transmit signals in the form of radio waves, which are then received by the vehicle's receiver to perform corresponding actions. Facilities such as high-voltage power towers, radio base stations, and even thunderstorms and heavy fog can interfere with radio waves, causing the car key to not respond no matter how much it is pressed. 2. Building obstruction. Radio waves have a certain penetration capability, allowing us to operate the remote even through a wall or a building. However, as the battery power decreases, the strength of the radio waves is also affected. It may work fine when used face-to-face, but the waves may not penetrate when obstructed by buildings. 3. Low battery. As mentioned above, as the battery power decreases, the range and strength of the radio waves diminish. When fully charged, the remote might work from 100 meters away, but with half the battery left, the operational distance might be reduced to only 50 meters. At this point, if you operate the key from 50 meters away, you might only see the indicator light on the key turn on, but the car will not respond. 4. Loss of remote key code. Placing the key in a strong magnetic field or high-temperature environment may cause the loss of the remote key code, resulting in the car key not responding even when it has power. In this case, you need to visit a 4S shop or a professional car key store to re-match the remote key. 5. Remote key circuit board failure. The symptoms of a remote key circuit board failure are similar to the loss of the key code, but the difference is that the remote key can no longer be re-matched and must be replaced with a new one. At a 4S shop, replacing the key involves using a blank remote key sent by the manufacturer and matching it with your car.

Should the Wrongly Mounted Tire Be Reversed Back?

Tires that are mounted incorrectly need to be reversed back. Here is the relevant introduction about car tires: 1. Reasons why tires cannot be mounted in reverse: The main reason tires must be installed according to the specified direction is that the tread pattern design and its orientation have a front and rear directionality, which plays a key role in drainage, anti-slip, and other aspects during normal driving. 2. Wrongly mounted tires affect braking performance: Incorrect tire mounting can reduce the car's grip, create uneven resistance on both sides, thereby affecting braking performance, and also accelerate tire wear. This can easily lead to the car pulling to one side and unstable steering.
