Electronic rust protection, Does it work? Options

[Mangozac]

Hi everyone,

OK a friend of mine works in aftermarket car sales so she sells stuff like tinting and mats and rust protection.

I live by the beach and unfortunately I'm not able to garage my pride and joy so I was thinking that rust protection would be a good investment, especially seeing as I can get it on the cheap

The question is though, does it really work? The car is still in quite good nick and other than a few stone chips there is very neglible rust around. I've read the theory on the electronic rust protection and it makes sense but I remember that people are always scoffing at it whenever it is mentioned.

So if anyone can confirm its' performance either way it would be appreciated.

Zac
