For polishing, many car owners have heard about it, but for those who don't know the car, there are many related questions and they are easy to be confused. Then we will answer the question mentioned by many netizens: must the car be polished after painting? Is it OK not to polish the car after painting?

一般汽車(chē)表面噴過(guò)油漆之后，可能會(huì)出現(xiàn)粗粒、流痕、反白、砂紙痕、橘皮等漆膜表面的細(xì)小缺陷，為了彌補(bǔ)這些缺陷，通常在噴涂后使用汽車(chē)拋光研磨劑，來(lái)進(jìn)行研磨拋光處理，這樣可以提高漆膜的鏡面效果，達(dá)到平滑、光亮、艷麗的要求。所以說(shuō)汽車(chē)噴漆后還是有必要做一下拋光的。

Generally, after spraying paint on the surface of automobile, there may be small defects on the surface of paint film, such as coarse grain, flow mark, whiteness, sandpaper mark, orange peel, etc. in order to make up for these defects, automobile polishing abrasives are usually used after spraying, so as to improve the mirror effect of the paint film and achieve the requirements of smooth, bright and gorgeous. So it is necessary to polish the car after painting.

拋光的利與弊相信很多車(chē)主都有討論過(guò)，事實(shí)上頻繁的拋光會(huì)讓車(chē)漆越拋越薄，甚至有可能出現(xiàn)拋穿的可能，所以業(yè)內(nèi)人士提醒，拋光在一輛車(chē)的一生中，更好不要超過(guò)5次。

The advantages and disadvantages of polishing are believed to have been discussed by many car owners. In fact, frequent polishing will make the paint thinner and thinner, and may even cause the possibility of polishing. Therefore, insiders remind that it is better not to polish more than five times in the life of a car.

那么什么情況可以起拋光呢？首先，新車(chē)不需要拋光。一般使用了3-4年的汽車(chē)，車(chē)漆已經(jīng)失去了新車(chē)的光澤，而且多了很多細(xì)微劃痕，那么這時(shí)可以通過(guò)拋光的方式來(lái)使車(chē)漆煥然一新。

So what can be polished? First of all, new cars don't need polishing. Generally used for 3-4 years, the car paint has lost the luster of the new car, and there are many small scratches, then you can polish the car paint to a new look.

拋光必須謹(jǐn)記步驟，首先要清洗整輛車(chē)，避免顆粒灰塵在拋光中造成新劃痕。接著在拋光前用水砂紙對(duì)車(chē)漆進(jìn)行打磨，注意不能磨穿漆層，輕輕打磨即可。

The polishing process must be kept in mind. First of all, the whole vehicle should be cleaned to avoid new scratches caused by particle dust during polishing. Then polish the car paint with sandpaper before polishing. Pay attention not to wear through the paint layer, but to polish it gently.

然后采用研磨機(jī)加上研磨膏進(jìn)行拋光研磨，這個(gè)步驟非常關(guān)鍵，需要經(jīng)驗(yàn)豐富的師傅來(lái)操作。研磨拋光結(jié)束后，擦凈車(chē)身，立即用光油蠟對(duì)拋光部位進(jìn)行擦拭，使車(chē)漆恢復(fù)光亮。

Then use grinding machine and grinding paste to polish and grind. This step is very important and requires experienced master to operate. After grinding and polishing, wipe the car body, and immediately wipe the polished parts with polish wax to restore the brightness of the paint.
