How does a soda can manufacturer print the logo and info on an aluminum can?
I thought maybe they were color anodized at first because they are so
durable, but after closer inspection and playing around, I think it is some
kind of super durable ink spray or silk screen process.

Acetone doesn't touch it and even a wire wheel takes a slow or deliberate
pass to remove it all.

Anyone know for sure?

Back when I did a little sal****er sailing, I was
struck by the irony of SS rusting, but pop cans
staying intact for years in a marine environment.

I think there's some kind of acrylic coating over
top of the printing.
