When I first got my car I called the dealer and asked about rust proofing. They said that BMW does a pretty good job on that when the car comes off the assembly line and not to worry about it. I believed them because my dad had an '85 528, he drove it every winter and not one spot of rust. But last year after the winter I noticed a few small areas on my car with some rust. Of course I got them cleaned up right away but before this winter I decided to get my car rust proofed. I was wondering what other people on these forums do.
Also, today I saw an add for a device called Counteract. From what I understand it provides a small current to a car's metal body which aids in preventing rust.
Here is the link: Counteract
Anyone hear/try a product like this? Just wondering if it really works.
Man am I jealous of you guys in the Southern States. It's so warm and dry there you probably never have to worry about rust.
