That just cannot happen. PREVENT, that is.
Except for the fact that exhaust pipes ALWAYS rust from the inside out, it's just
that the outside is easy to see. That's one reason (aside for performance and
function) why ceramic coating is done both inside and out, and now different
coatings are used inside.
