The early 80s Corvette used titanium for the air filter cover. There had to be all sorts of bulletins for mechanics. Even though the cover was held on by large plastic thumb screws (and thus needed no tools for removal) it was a very convenient flat spot in the center of the engine compartment for placing tools on. The cadmium coating on hand tools will cause titanium to corrode, so don't use ordinary hand tools.
That's super interesting, I did not realize that. Isn't Cadmium banned nowadays? It's a pretty bad compound to ingest, especially in dust form. Not quite Beryllium Oxide but not exactly flour either.
