Linseed oil on metal would be good. It is edible. I use the raw on exposed wood on my porch and also on the kitchen cutting boards to help preservation. You can add the mold inhibitor from the local paint store on the outdoor stuff.
So we could recycle the cars body panels by eating them, good to know as there will be plenty of iron in the meals. A balanced diet would need you to eat the wheels, that’s not going to happen as rubber is just too chewy. 😜
