If you wish to continue with crystal coating after one year, the car owner can directly visit a 4S store for crystal coating maintenance. If you choose not to continue, it will not harm the car, but the protective effects of the coating will gradually diminish once the layer is gone. Below is a detailed introduction to vehicle crystal coating: 1. Definition: Crystal coating is a hard protective layer specifically designed for key areas of a car, such as the paint surface, glass, tires, rims, seats, engine, interior, and exterior trim. The materials used in crystal coating mainly fall into three categories: polysiloxane, polysilazane, and inorganic silicon. 2. Function: The highly resilient crystalline layer tightly adheres to the paint surface, effectively preventing cracking and peeling caused by thermal expansion and contraction. Its unique memory molecular structure also helps repair minor scratches on the coated surface.

Last year, I also had my car coated with crystal, and after a year, the coating noticeably thinned, with water droplets not rolling off as easily during washes. First, do a self-check: find a shaded area, splash some water to see if it still forms beads. If the water spreads out directly or leaves water marks, it means the crystal coating protection has failed. You can visit a professional auto detailing shop and have the technician use specialized equipment to measure the paint thickness before deciding whether to polish off the old layer and apply a new coating. The entire process takes a few hours and costs anywhere from a few hundred to a thousand yuan, depending on the type of crystal coating chosen. For maintenance, it's recommended to wash your car gently once a month, avoiding hard brushes or strong cleaners to prevent accelerating coating wear. Remember, crystal coating isn't permanent—it's normal for the effect to degrade after a year. Don't delay treatment to avoid corrosion from acidic or alkaline rain and snow.

As a DIY enthusiast, one year after applying ceramic coating to my car, I use a simple method to check its condition: spray a bottle of hydrophobic test fluid on the hood. If water doesn't bead and roll off quickly, it's time to prepare for reapplication. You can try spot cleaning first by using a dedicated degreaser to remove old residue, but avoid polishing yourself as it may scratch the paint. I recommend visiting a reputable shop for professional assessment on whether recoating is necessary. If budget is tight, opt for a basic ceramic coating package - spending a few hundred yuan can extend protection for another year. Daily maintenance is crucial; I wipe my car weekly with a microfiber cloth and avoid prolonged parking under direct sunlight, which can extend the new coating's lifespan by several months. For frequent drivers, consider environmental factors - heavy pollution in big cities accelerates coating degradation within a year.

After one year, the protective effect of crystal coating diminishes, so it's essential to inspect and address it promptly to ensure driving safety. First, observe the glossiness of the paint and the adhesion of stains. If you notice an increase in scratches or reduced water beading, it's time to consult a professional shop. They may recommend polishing to remove the old layer and applying a new coating to prevent UV damage and corrosion. Avoid washing the car too frequently—once every two weeks is sufficient—and use a neutral car shampoo to protect the coating. From a safety perspective, degraded coating increases accident risks, such as reduced visibility during rainy nights, so don’t skimp on this small expense. Act quickly; the cost is manageable, usually just a few hundred yuan.

Can You Take the Subject Two Test Without Passing Subject One?

Normally, you cannot practice for Subject Two without passing Subject One. The prerequisite for learning Subject Two is passing the Subject One exam and obtaining a driving study certificate. This certificate serves as a practical training permit, allowing you to begin hands-on driving practice. Additionally, this certificate is valid for three years, during which you must complete all other subjects except Subject One; otherwise, you'll have to start over. Generally, driving schools will have students practice basic skills before moving on to Subject Two, such as operating the clutch, steering, and shifting gears. Once these fundamentals are mastered, students may practice moving forward and backward to grasp the concept of half-clutch control. The key to Subject Two is controlling the vehicle speed with the clutch, with little to no use of the accelerator. After mastering clutch control, students begin practicing the actual Subject Two test items. For C1 and C2 driver's licenses, you must wait at least ten days after obtaining the driving study certificate before you can schedule the Subject Two test. The vehicle management office will issue the driving study certificate within one day after passing Subject One. Therefore, it takes at least ten days after passing Subject One to meet the conditions for scheduling Subject Two. For first-time applicants or those applying to upgrade to large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large trucks, they must wait at least twenty days after obtaining the driving study certificate before scheduling the test.

How Many Years Can a Car Be Driven Before It Can Be Scrapped?

For domestic 5-seat sedans and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial sedans, and wheeled special machinery vehicles also have no usage period limit. Commercial vehicles have a scrapping period, as follows: Small and mini taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles have a scrapping period of 10 years, and large taxi passenger vehicles have a scrapping period of 12 years. Public transport passenger vehicles have a scrapping period of 13 years, other small and mini commercial passenger vehicles have a scrapping period of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping period of 15 years. Mini commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out one copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, Scrapping Approval Application Form" and stamp the owner's seal. The registration office accepts the application and issues a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, the motor vehicle inspection office will determine if they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if they do. The owner chooses a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company dismantles the vehicle and takes photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner submits the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and vehicle dismantling photos to the motor vehicle inspection office for verification and signature. The license plates are then recycled, and the scrapping registration is processed according to regulations. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to non-commercial use, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of motor vehicle registration, the original owner can apply to use the original license plate number when registering a newly purchased vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation registration; (2) The owner must have owned the original vehicle for more than three years.

Does Tire Patching Affect Driving on Highways?

Tire patching still allows for highway driving. Here is some information about driving on highways with patched tires: Conditions: Tires repaired at authorized 4S stores can continue to be used. However, due to the quality of the repair or aging of the patch over time, air leakage may occur. If you continue to drive at high speeds without realizing this, prolonged driving with low tire pressure could cause sidewall damage, leading to tire failure. Therefore, patched tires carry certain safety risks compared to intact tires. Recommendations: For the sake of highway driving safety, it is generally advised to move patched tires to the rear wheels or use them as spare tires. This helps minimize the potential adverse effects of compromised tire performance on highway safety.
