Sheet metal painting is a kind of automobile repair technology, which is to repair the deformed part of automobile metal shell. For example, if the car body shell is knocked out of a pit, it can be restored to its original state by sheet metal, and then the deformed car metal surface can be restored to the same brightness as other intact places by spraying special paint.

In order to be more perfect and accurate, we need to use sculpture techniques to make up for the defects. After the car is deformed and damaged for other reasons, every part of its flatness, wheel angle and line needs scraping and polishing.

Explain with this formula: scraping ash = repairing body skin = mold product = mold processing program. Any body skin of an automobile is stamped by a mold. Repairing body skin is like repairing a mold, so the molding process should be consistent with mold processing.
