High cost, extremely high requirements for the construction environment and technical skills are all disadvantages of crystal coating. Below is a detailed introduction to the disadvantages of crystal coating: 1. High cost: The comprehensive market price of crystal coating ranges from around 1000 to 5000. For car maintenance and beauty, crystal coating is quite expensive. 2. Extremely high requirements for the construction environment and technical skills: Crystal coating construction is complex and demanding, requiring professional training for the technicians and a high-standard environment, such as a dust-free workspace. The skill level of the technician directly affects the effectiveness and lifespan of the crystal coating. 3. Crystal coating construction may wear down the car paint: Polishing the car paint is necessary before crystal coating. Generally, a car can withstand about 7 polishing sessions, and the lifespan of a single crystal coating is about 2 years. Too many crystal coating sessions can be counterproductive and damage the car paint.

Honestly, I've had bad experiences with ceramic coating. The first year I spent over 3,000 yuan on it, and the car wash shop hyped it up saying it would last three years. But after just eight months, I noticed the water beading effect weakened - raindrops wouldn't roll off anymore. The most annoying part is that reapplying coating requires polishing first, and each polish wears down the paint. My black car now shows obvious swirl marks in sunlight. Plus, bird droppings must be wiped off immediately after coating, or they'll leave stains. My colleague who uses wax spends just tens of yuan every couple months doing it himself. Later, my cousin who works in used cars told me ceramic coating doesn't increase resale value at all - buyers only care about scratches on the paint.

Is 40 or 30 engine oil better for Haval F7?

Haval F7 is better with 40 engine oil, as 40 oil is more viscous than 30 oil. Introduction to engine oil: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the deficiencies in the performance of the base oil, giving it certain new properties, making them an important part of lubricating oil. Selection of engine oil viscosity: It should meet both low-temperature startability and high-temperature lubricity. Choose the viscosity grade according to the region, season, and temperature, and try to use multi-grade oil. In winter in extremely cold areas, engine oil with OW, 5W, or OW/20 or 5W/20 multi-grade oil should be selected. In summer in hot areas, 40 engine oil or 20W/40 engine oil should be used.

What is the normal tire pressure for Emgrand GS?

The normal tire pressure for Emgrand GS is within the range of 2.4-2.5 bar. According to the international standard GBT2978-2008, the tire pressure requirements for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Hazards of excessive tire pressure: Reduced friction and adhesion of tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreased puncture resistance. Sharp objects like nails or glass on the road can easily penetrate the tire, leading to internal cracks, blowouts, and tire bursts.
