Who is correct regarding the cleaning process before sanding a vehicle?

In the cleaning process before sanding a vehicle, the importance of thoroughly cleaning the surface cannot be overstated. Proper cleaning ensures that any contaminants such as dirt, grease, wax, or old paint do not interfere with the sanding process. This leads to better adhesion for paint and repair materials applied later.

If Technician A emphasizes that the vehicle must be washed and dried properly before sanding begins, this is key because any leftover contaminants can cause scratches during the sanding process or lead to peeling and flaking of new paint. A clean surface allows for even sanding and a smoother finish once repairs are completed.

Understanding the cleaning processes helps technicians ensure that they are laying a strong foundation for the subsequent steps in the repair process, aligning with industry best practices for vehicle restoration and repair.
