You can also throw some salt over your shoulder. (At least it wouldn't be
near the metal).

Click and Clack's (the guys on NPR) looked into supposed add-on cathodic
protectors and the result? About as close to a hoax as one can get in the
American marketplace. (Which is pretty darn close). Maybe Volkswagen has
cathodic protection but it didn't help my VW's rusted hatch. Perhaps Mr.
Kweeder could report on the results of his experiments.

In short, Mr. Kweeder, you may be able to argue theory, but the practical
application suffers.

Of course, keeping the automobile submerged in a 100ml beaker will allow
for that desired current flow. ;-)
