Rust Protection

[casterqc]

I've decided to start a new thread on rust protection, for those like me who have to deal with the snow...and the others who simply care.

I know there is already a thread on this but it ended up debating if rust protection was good or not.

Please lets only make this thread a good source of information for people that want to choose a good rust protection product.

Personnaly I never used any rust protection on my cars...and ended up dealing with surface corrosion and also perforation...don't want this to happen to my new car!

I know there is oil treatment you can put every year.
There is the wax treatment you can put every 2-3 years.
And also, new to me, the electronic device you can install for 200$can that protects your car from rust (like Counteract)

Have you ever use one of these products? What are your pro's and con's?
