Rusty Bucket - the old (now gone) total sealed Fab. *Fairchild Semiconductor.

There are other examples in San Jose.

It gives a redish rust and it is tough.

Also - the greenish rust on 'Army' rifles is a rust that locks out
other versions of rust.



Army rifle finish is parkerizing, or properly "Parkerizing", since it
is/was a finish of the Parker company. That's a phosphate finish, not
oxide, so not "rust".
