Who is correct about the use of body filler and lead in sheet metal repair?

In the context of body filler and lead in sheet metal repair, Technician A likely emphasizes the use of body filler as the modern and preferred method for repairing dents and imperfections in metal surfaces. Body fillers, such as polyester resin, are widely used in the auto body industry due to their ease of application, durability, and ability to be shaped and sanded for a smooth finish.

Using body filler is generally considered safer and more effective than lead, which was commonly used in the past. Lead-based repairs can pose health risks due to lead exposure, and the techniques required for working with lead are more complex and require specialized skills. Moreover, the application of lead for repairs can be less practical compared to the flexible and user-friendly nature of modern body fillers.

Therefore, Technician A's viewpoint aligns with current best practices in auto body repair, emphasizing safety and efficiency in using materials that are both effective for repairs and safer for the technician.
