What is the difference between automotive paint crystal coating and film coating?

4 Answers

Automotive paint crystal coating and film coating differ in the following aspects: 1. Different composition: The main components of film coating are generally organic and inorganic materials, while crystal coating primarily consists of silicon dioxide inorganic materials. 2. Different hardness: Crystal coating forms a crystalline structure, making it harder than film coating. 3. Different brightness: Crystal coating exhibits higher diamond-like crystal brightness. 4. Different durability: Crystal coating, being an inorganic crystalline material, offers greater stability and longevity. Additional information: The advantages of automotive crystal coating include: 1. Scratch resistance: Diamond crystal hardness reaches 6H, compared to the 2H hardness of standard car paint, effectively preventing most minor scratches. It also features elastic recovery properties, protecting the vehicle from daily minor scratches and reducing paint scratches by over 70% compared to regular film coatings. When external forces exceed the elastic protection range of the crystal, it typically only leaves scratches on the crystal layer without damaging the underlying paint. 2. Corrosion resistance: The ultra-fine nano-crystalline layer of diamond crystal isolates the paint surface from external elements, effectively preventing oxidation and resisting corrosion from bird droppings, insect residues, acid rain, etc.

I maintain my car regularly and have personally experienced the difference between ceramic coating and paint protection film. The paint protection film is like a thin protective layer, akin to putting a raincoat on the car's paint—it can shield against dust and rain stains but isn't very scratch-resistant and usually lasts about half a year before needing a redo, though it's relatively cheaper. Ceramic coating, on the other hand, uses nano-crystals, such as silicon, making it much harder and feeling like it merges with the car's body. It protects against small stone scratches, resists chemical corrosion, and blocks UV rays, lasting one to two years without issues. Although ceramic coating is more expensive, it’s more hassle-free in the long run, especially if you frequently drive long distances.

When working in auto repair shops, I've seen plenty of choices between ceramic coating and liquid coating. Liquid coating is mainly a liquid layer, simple and quick to apply - just spray a layer and let it dry. However, it offers weaker protection and is prone to wear or bubbling. Ceramic coating involves a chemical crystallization process that requires polishing the paint surface first, then applying a special liquid to form a silicon-based crystal layer with 9H hardness, which is much better than liquid coating's 6H. It also excels in durability, with excellent acid rain resistance and anti-aging effects. Overall, ceramic coating costs more but provides longer-lasting paint protection, avoiding the hassle of later touch-ups.

From an economic perspective, I consider ceramic coating and paint protection film (PPF). PPF is cheaper, costing just a few hundred yuan, making it suitable for short-term needs. However, its effectiveness is short-lived, lasting only six to nine months before it wears off, requiring frequent maintenance. Ceramic coating, though more than twice as expensive—potentially costing over a thousand yuan—can last for one to two years or more. It reduces the frequency of car washes and repair costs, ultimately saving money in the long run. Especially since I live in a polluted urban area, ceramic coating significantly reduces dust accumulation, offering better cost-effectiveness. If saving money is the immediate priority, opting for PPF as a transitional solution is fine, but investing in long-term protection is more worthwhile.

What causes the starter to smoke?

The reasons for the starter smoking are: 1. The engine temperature is too low: some diesel fuel does not burn and turns into oil vapor, which is discharged from the exhaust pipe along with the exhaust gas; 2. There is water in the fuel supply system: water in the fuel or combustion chamber is heated by the heat released during combustion in the cylinder and turns into steam, which is discharged from the exhaust pipe, forming white smoke; 3. The fuel injection timing is too late: due to the delayed injection timing, the cylinder temperature has already dropped when fuel is injected, causing some diesel fuel to not burn and turn into oil vapor, resulting in white smoke; 4. Poor atomization of the fuel injector: poor atomization leads to incomplete combustion of diesel fuel, which mixes with the high-temperature exhaust gas from normally operating cylinders in the exhaust pipe, causing white smoke; 5. The cylinder pressure is too low.

What should be paid attention to when driving in low visibility conditions?

When visibility is low, attention should be paid to using fog lights and operating the vehicle correctly: Always use fog lights: In foggy weather during early morning or evening, do not use high beams as they can make the road ahead even less clear. Turning on fog lights can help other pedestrians and vehicles see you, avoiding accidents. Use the car horn appropriately: Due to low visibility and poor sight, it is advisable to use the horn appropriately while driving to warn surrounding pedestrians and vehicles. Additionally, when hearing other vehicles' horns, respond by honking to indicate your position. Avoid sudden braking: When driving in low visibility conditions, avoid slamming on the brakes. Give the vehicles behind you adequate reaction time. When braking, start slowly and gradually reduce speed. It's best to take measures to alert the vehicles behind you.

Can I add vehicle damage insurance later if I didn't purchase it initially?

Yes. Additional extended information is as follows: 1. The "Motor Vehicle Damage Insurance Clauses" has corresponding provisions: Article 15 states that unless otherwise agreed, the insurance period of this contract is one year. If the insurance period is less than one year, the premium shall be calculated according to the short-term monthly rate approved by the insurance regulatory authority. The insured shall provide the insurance company with the insurance policy, the driver's license, the insurance vehicle's driving license, accident certificate, traffic accident determination letter, loss list, and other certificates and materials related to confirming the nature, cause, and extent of loss of the insurance accident. 2. Relevant provisions of the "Motor Vehicle Damage Insurance Clauses": Article 22 states that the insured vehicle damaged in an insurance accident should be repaired as much as possible. Before repair, the insured must inspect with the insurance company to determine the repair items, methods, and costs. Otherwise, the insurance company has the right to re-evaluate, and if re-evaluation is impossible, the insurance company has the right to refuse compensation.

Why are the production dates of the new car's windows different?

It is normal for the production dates of the new car's windows to be different, as long as the production date of the windows is earlier than the manufacturing date of the entire vehicle. The car's windows are purchased externally and then assembled onto the vehicle. During installation, they are randomly installed according to the production batch of the windows, so different dates are normal. Here's how to interpret the production date of car windows: 1. Currently, the most common method for indicating the production date of windows on the market is a combination of numbers and dots, where the numbers represent the year and the dots represent the month; 2. The dots can be placed either before or after the numbers. Dots before the numbers indicate the first half of the year, and the month can be calculated by subtracting the number of dots before the numbers from 7; 3. Dots after the numbers indicate the second half of the year, and the month can be calculated by subtracting the number of dots after the numbers from 13.
