When I was in college, I knew a guy who was a chemical engineering
student that got the bright idea of trying to rig up an active
anode on his Ford Fairmont.  He would up eating the hell out out of
several parts of the unibody where it joined the front subframe
within a couple months of time.

I'd strongly recommend debugging one's technique on a car that one
can afford to mess up before trying it out on the ole Porsche 944.

I live in northeast Ohio which uses more winter road salt than
most other parts of the US.  I've found that the best method of
rust prevention is to frequnently wash the car.  I have a 1983 AMC
Alliance (no laughing please) that's got about 73K miles on it.  It
has received no rust prevention other than what it got from the
manufacturer; to date, it has virtually no corrosion problems.

What I'd like to know is if those cars that have stainless steel
exhaust systems never need to have the pipes replaced.  So far,
I've nver been able to get a tailpipe/muffer to last more than
about 4 years.

Spend a buck a week and go to one of those do-it-yourself car
washes with the power wand and wash out the underside of your car.

Salt is a four-letter word,
Bill
