Yup.

Have you ever media-blasted an aluminum component after an electrolysis problem- it's horrifying. It can look like the part in your hand is all aluminum and intact before you start, but when you start blasting, the cancer is cleaned away, and you're left holding something that looks more like a piece of Swiss cheese.
