It would be interesting to know. Here is an interesting anecdote.
I worked for most of my life in the industrial coatings business. I mostly formulated clear finishes for wood. A common finish system used for kitchen cabinets required an acid catalyst (PTSA). To ship this by air was a pain, regulations required multiple layers of packaging because it was "corrosive". One day, annoyed after having to pack and ship some of this stuff and somewhat curious, I wadded up a ball of aluminum foil (aluminum, what airplanes are made of) and dropped it in a bottle of PTSA. Nothing really happened. So I screwed the lid on and set it aside.
Two years later the wad of aluminum foil was still shiny, sitting in it's bottle of "corrosive" PTSA.
