Laser stripping is an advanced technique used to remove paint, rust, and other contaminants from metal surfaces with precision. In the process of laser stripping a Lada shell, a laser is employed to target and remove layers of unwanted material from the vehicle's body. This method is highly efficient and minimizes damage to the underlying metal. 

Before the stripping begins, the Lada shell is weighed to establish its initial weight. After the laser stripping process is complete, the shell is weighed again to determine the amount of material removed. This technique not only improves the aesthetics of the vehicle but also helps in preparing the shell for further restoration or painting.

The weight comparison provides insight into the effectiveness of the laser stripping process and the amount of material that was removed.
