Before we talk about the best vehicle undercoating products, let’s tackle the root of the problem in the first place: Rust.

 

Rust will literally eat away metal. If you can imagine the undercarriage of an old car, you would probably find a lot of rust formation. If left unchecked, rust will consume the entire undercarriage, and this affects the overall integrity of your vehicle.

Before we get into the meat of how to prevent rust, it’s important to know what rust actually is. So to get a little bit technical, here’s some science…

Rust is an iron oxide that’s created by the presence of three things: an anode, a cathode, and an electrolyte. To quote How Stuff Works, “an anode is a piece of metal that will readily release electrons under the right circumstances. Cathodes are metals that will accept electrons. Electrolytes are liquids that facilitate the movement of electrons.”

Simply put, the metal in your car acts as both an anode and a cathode, while water (from rain, puddles, humidity, etc) is the electrolyte. It’s important to remember, however, that water alone is a poor carrier of electrons. What really does the job well is salt, which is why cars exposed to road salt and brine will accelerate the process considerably.

 

So what products can protect cars from rusting?

 

Some people take care of the paint and the interior, but those who really know cars will also take the time to protect the undercarriage using the best car undercoating sprays.
