In many people's eyes, if the paint becomes dim, or if the appearance shows sun lines or other scratches, just stop polishing. The construction time is short, the price is comparatively economical, and the effect is quite obvious. In practice, polishing seems to be the most direct and effective way. But the varnish itself is limited in thickness, and polishing time after time will make the varnish layer thinner and weaker, and eventually lose the ability to maintain the primer.
Before the appearance of invisible garments, we usually used waxing, glazing, coating and crystal plating to maintain the paint surface and prolong the life of the car paint. Waxing is one of the lowest cost ways. Its principle is to fill the pits of scratches with tiny wax components to restore the surface smoothness. At the same time, a thin wax film is formed on the paint surface, so that the paint surface does not contact with the air directly, thus slowing down the oxidation speed of the paint surface, and reducing the damage to the paint surface caused by larger particles in the air and ultraviolet rays in the sun. Waxing does brighten the car paint in a short time, but due to the soft nature of the wax itself, the durability is very limited. In general, if you wash the car two or three times, the wax layer will disappear completely. Sealing glaze and coating are more durable and easy to operate than waxing.
Both of them can be regarded as one thing. They are also sprayed with "invisible maintenance layer" on the paint surface. However, the materials used are slightly different, and the cost of glazing materials is lower. Although durability is obviously better than waxing, glaze sealing and coating will gradually fade away over time, depending on the application environment, which can generally last for 3-6 months. In addition, there is also a fast coating product on the market today. It is said that one spray and one wipe is equivalent to waxing, and can achieve the effect of crystal plating. The cost-effective ratio is still possible, but the durability is somewhere between waxing and coating.
Regardless of the above methods, in fact, there will be reaction. Take crystal plating as an example. If the crystal plating layer disappears, the aging of car paint will accelerate if it is not crystallized again. And if the crystal is plated again, it is necessary to stop polishing the car paint before the crystal plating. Generally speaking, the car can usually accept about seven polishing times. If the polishing times are too many and the varnish layer is too thin, the varnish layer will be damaged. As long as the invisible garment is coated with a high brightness colorless maintenance film on the surface of the paint, instead of covering up a layer of chemicals, it will prevent the destruction of the paint itself. In fact, the professional term of invisible garment is called paint maintenance film. Because of the high hardness and toughness of the material itself, it can achieve more satisfactory protection effect than crystal plating in daily use, prevent the paint from being scratched by sand or sharp objects, or corroded by acid rain or bird droppings, and has the ability of anti-ultraviolet ray and anti-oxidation.
If after a long period of use, the invisible garments also show more obvious scratches, discoloration and other phenomena, and even damaged in the crash. At this time, just tear off the invisible clothes, the car will be a new look.
But many people will ask, the same film, why stick on the car, the price is tens of thousands? In fact, because the invisible garments have higher requirements for maintenance performance, durability, extension performance, aesthetic performance and so on, they also need to invest more capital and spirit to stop research and development. In addition to the value of the garment itself, the construction of the invisible garment is actually no less difficult than that of the plated crystal. Especially for some comparatively thick products, coupled with the complexity of many models, the technical requirements for the construction personnel are also comparatively high. But compared with the crystal plating that can last for 1-2 years, the general quality assurance of invisible garments is more than 5 years, some even up to 10 years. But the price is only about twice as high as that of crystal plating, so the cost-effective ratio is quite high.
