Just wondering if anyone driving their car in the winter with the snow and salt has applied a rust-proofing spray on their car? If so, what kind of product did you guys find works best?
I have to disagree. The reason they give a (usually 10 year) rust thru warranty is because car dealers know people will rarely keep their cars that long. And don't forget it's a rust THROUGH warranty, surface rust is excluded. You have to prove that the rust started under the paint and not from rock chips and such.it's fact that modern autos do not benefit from a coating. In the old daze we used Zeibart and others, may have been wasted even then. Note this process can be very heavy, why add more weight for no benefit?
Most sheetmetal in new cars is galvanized and/or treated specifically to stop rust, this is why we get a rust-through warranty on almost any new car.
BCasey....electric current somehow prohibiting a chemical reaction is proven to be bunk. Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron (and its alloys) in the metal with oxygen in the presence of water or air moisture. Other metals also undergo corrosion, but the resulting oxides are not commonly called rust. Given sufficient time, oxygen, and water, any iron mass eventually converts entirely to rust and disintegrates (the corrosion of aluminium is extremely slow because the resulting aluminium oxide forms a coating, which protects the remaining aluminium).I got a rust protection warranty for my car. They spray it and give me one of those little boxes that keeps a current running through the car to stop rust.
