My dad was a body and fender man for over 50 years. He also owned his own shop. Bondo dust, paint fumes, working with lead, welding fumes, grinding particles and asbestos. One would think that is what led to his death. Not so. It was the 2 pack a day smoking habit. I think that we are all safe. Unless we are pre-disposed to some chemical that will affect our health.
