underbody/engine block rust prevention?

Unless you get harsh winters in a city where the plowmen like to spread a crap load of corrosive rock salt and calcium on the streets, or if you're in a coastal city where you get a lot of sea breeze and fog, you will not need rust proofing or any sort of undercoating. That being said, it's definitely not a bad thing to be safe rather than sorry, but in all honesty today's cars don't rust like they did, heck, two or three years back. If you keep a good coat of wax on your sheet metal and don't let your car sit unattended, outdoors, for too long you shouldn't have any problems. Undercarriage oxidation will eventually occur, but any rotting of the rocker panels, frame or sub-frame is highly unlikely in this day and age.

If your car won't see any winter, you shouldn't have to worry about it.

I checked under my car about two days after I got it and there was already rust on part of the steering linkage. I have pics back home.. I couldn't believe it.

Normal, honestly. I was appalled to find that my brand new Mazda 3 had some surface rust on the hubs when I removed the wheels to put on the winter set, but then I remembered that pretty much every car at the shop, from Geo Metros to brand new BMWs, had this.

Perfectly normal. All cast iron parts will rust. The tie rod, hub areas, and brake rotors are all cast iron. Don't like it? Wire brush and coat with POR15 , Rustoleum, or other coating..

any recommendations on which product/company to use for rustproofing
want to get it done before winter starts
living in Canada the amount of salt on the roads is pretty bad
never done it to any previous vehilces
heard the oil spray is messy and not as good as some other methods
Thoughts?
