I would like to coat some of the hotter parts of the exhaust system too...
mostly just to look real cool, in black and all....

But was wondering one thing...

What causes these parts to rust through faster, the outside (relatively mild
in comparison) salt and water... or the inside moisture, mixed with sulferic
acid, or whatever else the combustion produces that is nasty, and sits it
the pipes after you get back from the store.
