The fumes would clear the entire factory within the first 20 minutes. Sanding it would kill them all within a week.
We used to use Bondo on restoration projects, rebuilding old window frames and decorative work that couldn't be replaced but that was OUTDOORS. I was on a commercial jobsite once where someone thought it was a good idea to use it inside on some metal door frames.
The real icing on the cake was when they were sanding that shit while the new tenants were moving some stuff in. No ventilation, no masks, and no vacuums, they were trying to sweep up the dust which just resuspended it. When everyone started choking and complaining, they ignored it. When the contractor was called he wondered what the problem was. It all ended in a class action law suit that put the contractor out of business.
It's not that you couldn't use Bondo as wood filler, it's just that nobody in their right mind ever would for that application inside a factory. There are just too many better alternatives
