The appearance of rust on your car not only detracts from its value, but can impact its performance in some cases as well. And while there's no 100%-guaranteed way to keep the metal parts of your car from rusting, the good news is that there are a few simple yet effective steps that all vehicle owners can take to help protect a car from rust or, at the very least, slow down the oxidation process.

Apply a Rust Inhibitor Spray

One of the most effective ways to protect a car from rusting is to apply a rust inhibitor spray to the vehicle's exterior once every couple of months. Specifically, a rust inhibitor spray works by creating a thin, transparent layer of protection over the car's metal surfaces. This layer acts as a film that prevents water from penetrating it and oxidizing the metal underneath (which is what leads to corrosion and rust in the first place).

If you already have rust forming on your car, you may also want to use a rust inhibitor spray specifically designed to slow the progression of rust by absorbing oxygen around the affected area.

Wax (Don't Just Wash) Regularly

Many car owners think that by simply washing their cars regularly, they're protecting them from rust. While it's true that washing your car can remove harmful debris, such as dirt (which acts as a catalyst and speeds up the oxidation process in metal), washing alone isn't the best thing you can do for your car. In addition to washing, you should also take the time to wax your car regularly, which will help build up a protective layer while keeping your car looking shiny and new. You can wax your car yourself or have it done at most drive-through car washes.

Take Advantage of Covered Parking

Finally, whenever possible, keep your car parked under a covered spot, such as in a garage or carport. This is especially important while it's raining or humid outside, as parking in a covered spot can help to protect your car from the moisture that can start or speed up the oxidation process on car metal. Parking in a covered spot will also help to protect your car from other harmful elements. If you don't have access to a covered parking spot or carport, consider parking underneath a tree or other shaded area so as to minimize your car's exposure.
