Car paint polishing should have been heard by most people, and the car wash would have used it as a maintenance project for car paints, such as a polishing of the entire vehicle prior to such projects as crystal plating or sealing. Some of the owners would also be willing to ask for a full-car polishing to make the paint look better and then look like a new car. There are also polishing services at 4s, such as small scratches on cars, car washes that can't be washed, which may not look good, or can be handled by polishing. Today i'm going to say, "what's the polishing, why don't we do it all the time?"
The polishing of the paint is the grinding of the paint, and it makes sense to polish the face of the shoes before polishing them. The paint of a car is complicated, not just sprayed on one level, but on several levels. At the bottom is the base paint layer, which is primarily rustproof and which also provides greater strength. The main colour of the base paint is gray, and occasionally black or white. It's painted on top of it. What color does our car look like, is black or white or red, and it's all painted。
The top of the paint, which is the outermost, is the varnish, which protects the varnish in it. It's like wearing a protective suit that's uv-proof, little stone-resistant. It also makes the paint smooth and smooth. The use of varnish is very wide, but everything that matters, such as household furniture, with spray paint, is at the top, and it's smooth。
When the vehicle has small scratches, it has to be polished when it is exposed to the wind, the acid rainbird manure is corroded, and the surface does not look bright and the surface of the varnish is damaged. The polishing requires a polisher, a small machine that rotates at high speed, similar to an angular grinder, with a polished sponge。
The paint is painted with the polishing of particles, and the surface of the varnish is polished by a high-speed rotation. So the scratches and the old paints were worn off, and the flat parts were shown, and the car lit up like it had just been sprayed. The principle is like grinding a rusty piece of iron with sandpaper, grinding out the rust on the surface, showing the iron inside, and making it smooth。
The polishing was not to repair the paint, but to grind out the damaged paint surface and show the good paint inside. Every time the light is thrown, the varnish is thinner, the less it is worn, the more it is. The total paint thickness of the vehicles is 120 to 180 micrometres, the thickness of the varnish is between 30 and 50 micrometres, and most vehicles are approximately 40 micrometres. It's not necessarily the thickness of the varnish that can be polished once in a while. Normal norms can polish about 3 micrometres at a time, with the potential to grind 5-10 micrometres if deep scratches are addressed。
Even a normal method of polishing can throw away dozens of times, and the paint is worn out. When the paint is gone, the paint inside will lose protection. Aging very quickly, the sun fades, it looks lightless, it looks dumb, it looks even worse. The oxidation occurs in a short period of time and is particularly susceptible to erosion and can even be scratched lightly. At that time, any paint maintenance was useless and had to be repainted for repair。
The polishing of cars should be counted as a means of repairing the paints, not as a conservation project, but at the expense of a small amount of paint for the overall beauty. So don't do it all the time, especially when the whole car is polished, and don't do it as a last resort. If the paint is scratched, it can be partially polished。
It is recommended that no scratches should be cast, since scratches are almost inevitable, and many of them never cross or follow the country's bushy roads, but sometimes they appear. It can be saved together, to a certain amount, to be polished together, with no more than once a year recommended. And it's best to find an experienced teacher. Don't hit too hard。
