Well, I worked in a sheet metal factory once and scarred my wrist from the cuts. I found a sympathetic psychiatrist who told the draft board I was insane. We used the scars as proof of a suicide attempt.
A mobile is an abstract sculpture made chiefly out of sheet metal, steel rods, wire and wood. Some or all of these elements move, propelled by electric motors, wind, water or by hand.

A lot of the jobs I had revolved around metal fabrication and creating and building and maintaining equipment.
I wasn't interested in car parts per se, I was interested in either the color or the shape or the amount... Just the sheet metal. It already had a coat of paint on it. And some of it was formed.... I believe that common materials are the best materials.

By trade I am a metal fabricator, so I have a degree in custom automotive fabrication.
