I get the rust concept. My mother had one of those old giant cadillacs fromm the late 70s/early 80s. I call them "land yachts". It was parked about 50 yards away from Tampa Bay in Florida, in a carport.

The mist of salt water from the bay "ATE" (rusted) the fins off the back of the dam car. We watched those fins slowly disappear. As the car got older parts would just simply drop off. I called it the "green beastie"

Alas, it went to the big parking lot in the sky. The rust monster ate it
