Who is correct about the use of body filler versus lead?

The use of body filler in collision repair is widely recognized within the industry due to its versatility, ease of application, and effectiveness in repairing dents, scratches, and other surface imperfections. Body fillers, such as polyester resin, offer excellent adhesion properties and can be sanded down to a smooth finish, making them ideal for achieving a seamless repair that blends well with the surrounding surfaces. This method has largely replaced lead, which was commonly used in the past for similar purposes but has fallen out of favor due to health concerns related to lead exposure and the difficulty of working with it.

Lead was traditionally used for filling gaps and smoothing out body panels, particularly in older vehicles. However, its use has diminished significantly because of the hazards associated with lead, both in terms of inhalation and environmental pollution.

Therefore, Technician A’s assertion about the common use of body filler reflects the current practices in collision repair, making it the correct statement in this scenario.
