Maintaining the body of your vehicle is just as important as maintaining its engine.
Fall is when most consumers think about rust control, but it's more ideal to perform the application this time of year. In the spring and summertime, the changing temperatures cause the metal on the vehicle to expand and contract more than in the fall and winter. This allows the product to penetrate even deeper into the body, although the product can be applied in any season.

There are some common myths around the use of oil spray, the most common being that it "drips" and could leave a mess on your driveway. The product may drip slightly, but it's a good thing. As the liquid finds its way into cracks and crevices, the excess tends to fall off of the vehicle. Personally, I've used the product for years and it's never left a drop behind. Another misconception is that cars with plastic panels won't benefit from the treatment. This isn't true. Your Saturn isn't made entirely of plastic, and there are many metal parts holding it together.

I asked a mechanic he thought of that kind of treatment. "I spray all of my cars. It protects vital components like brake and fuel lines as well as the unibody of the car" he says. The yearly application ranges in price from $110 to $140 and will prove to be far less expensive than repairing rust damage in the long run.

Another popular defense against rust is referred to as an electronic rust module. It represents a cutting edge approach to preventing rust by conducting a small electrical charge through the body of your car that interrupts the electrical exchange of ions that start the process of oxidization. Many carmakers offer it as a package with new vehicles, and cover them with a lifetime warranty against rust if their product is installed.

The effectiveness behind an electronic rust module is a little harder to grasp, and many will prefer the old-fashioned application of a physical barrier between the elements and the steel, though sales of the module are increasing.

Just like any other part of your vehicle, if you maintain it, it will reward you with long life, so if you've ever thought of protecting your ride against rust, now is the time to do it. Whether electronic protection or traditional oil spray appeals to you, maintaining the body of your car or truck for the long term stands to save you considerable time, money and hassle down the road.

There really is no excuse to be that motorist with the swiss-cheese rocker panels and duct-taped wheel wells now is there?
