Auto body workers were exposed to asbestos primarily through asbestos-reinforced body filler. For years, some automotive body fillers and putties were allegedly formulated with asbestos fiber for strength and sag resistance — and the dust released when those fillers were sanded was a direct exposure pathway for body-shop workers.
How Auto Body Workers Were Exposed
The hazard came at the sanding stage. After filler was applied to a dented panel and allowed to cure, body workers ground and sanded it smooth — releasing a fine dust into the shop air and the worker’s breathing zone. Because sanding was constant, dry, and rarely ventilated or wetted, body workers could inhale asbestos fiber daily over a career. Body workers also worked alongside brake and clutch dust in the same shops, adding to the exposure.
The Asbestos Materials — and the Products They Came In
Exposure tracked mainly to filler and surfacing products. Each links to products documented in the AsbestosIndex as allegedly asbestos-containing:
Asbestos-reinforced body filler (mixed, applied, and sanded):
- Bondo asbestos body filler · Bondo (Mar-Hyde) fiber-reinforced body filler
- 3M body filler / putty (fiber-reinforced)
Brake & friction dust in the same shops (body work often shared space with mechanical repair):
Take-Home Risk to Families
Like other dusty trades, auto body workers carried asbestos fibers home on their clothing, skin, and tools — exposing spouses and children who never worked with asbestos. See take-home asbestos exposure.
If you worked as an auto body worker and were diagnosed with mesothelioma or another asbestos-related disease after exposure to asbestos on the job, you may have a legal claim.
