1、 Shallow scratch: due to improper friction and daily care, there are slight scratches on the paint surface, but the primer is not exposed. This kind of scratch is more obvious in the sun. Usually removed by polishing.

二、褪色：大气中的油烟和污染物是造成车漆变色、褪色的主要原因。褪色与氧化不同，发生褪色时，车漆会出现不均匀的色差。中、轻度的褪色可用研磨、抛光治理，严重时重新喷漆。

2、 Fading: oil fume and pollutants in the atmosphere are the main reasons for the discoloration and fading of car paint. Fading is different from oxidation. When fading occurs, the paint will have uneven color difference. Moderate and mild discoloration can be treated by grinding and polishing, and repaint in case of serious discoloration.

三、水痕纹：水痕纹是水滴蒸发后留下的痕迹，呈环状。氧化、常用洗涤灵清洗的车容易染上水痕。

3、 Water mark: water mark is the mark left by the evaporation of water droplets, which is circular. Cars that are oxidized and commonly cleaned with detergent are easy to get water marks.

四、漆面氧化：在太阳紫外线的照射下，漆膜会不断向空气中蒸发油份以达到保护自身的作用，长时间就会导致漆面油分的过分散失。漆面的亮度都大打折扣，使漆面慢慢发白，形成氧化层，缩短了车漆的寿命，氧化严重的话可以通过研磨和抛光来处理。

4、 Paint oxidation: under the sun's ultraviolet radiation, the paint film will continuously evaporate oil into the air to protect itself, which will lead to excessive loss of paint oil for a long time. The brightness of the paint is greatly reduced, which makes the paint white slowly and forms an oxide layer, which shortens the service life of the car paint. If the oxidation is serious, it can be treated by grinding and polishing.

五、蚀痕：蚀痕是面状磨蚀。昆虫、鸟粪、树汁、焦油、沥青都有可能引起的蚀痕。轻微的蚀痕可用研磨抛光。

5、 Etch marks: etch marks are surface abrasion. Insects, bird droppings, tree sap, tar and asphalt may cause corrosion marks. Slight corrosion marks can be solved by grinding and polishing.
