Electronic Anti-Corrosion Systems

[Express]

Since moving near the water I’ve noticed surface rust on many things metal in and around my garage.

Things like some tools, the lawnmower frame & stored exhaust components to name just a few.

These same and similar items sat around my Sydney home (Ryde) for years without any noticeable corrosion.

Which has got me thinking about my cars.

I know most new cars are less prone to early rust problems due to various treatments during the manufacturing process but that doesn’t mean everything survives unscathed.

For example I notice I need to be more vigilant with cleaning exhaust tips otherwise surface rust quickly appears, I also have some older cars around that I have no doubt the salt air would find to be a delicious meal.

Which brings me to my question, is there any value in electronic anti-corrosion systems or are these just a rip off?

How do they actually work or for that matter, not work?

What do other members who live in coastal areas do or is it just a fact of life I have to live with?
