The repair process of automobile dents is different from that of sheet metal painting, and there are generally three factors that affect the price, such as the size, location and sharpness of dents. In the picture, the price of white area is relatively low, the price of gray area is slightly higher, and the price of red and black areas is relatively high.
Secondly, the sag is small, which is generally calculated by the maximum extension length of the sag. The longer the maintenance, the higher the price, so it is not calculated by area. Strip pits are more expensive than regular circular pits (this quotation is only applicable to Shanghai area).
The last criterion is the sharpness of the depression. The sharper the depression, the more difficult it is to repair and the higher the price.
