What is Car Rust Proofing?

Car Rust Proofing is accomplished by spraying a protective wax all over the car’s parts where moisture can accumulate to avoid any rust on your vehicle and protect your vehicle from environmental damage.

Over time, and with our daily consumption of the car, in addition to weather factors and sometimes our wrong practices, the car’s lower quality outer, and perhaps the most prominent problems that irritate us and sometimes exasperate us are the appearance of bubbles that appear under the paint or reddish-brown spots. It is car rust, which you must treat as quickly and decisively as possible so that it does not spread to larger areas and destroy your dear car. The importance of rust proofing car also goes beyond other reasons that may fall under your desire to sell or buy a car, as car rust spots have a crucial and essential role in turning the scales of the buying or selling process. So, here is everything you want to know about car rust, its causes, types, treatment methods, and much other important information.

What is car rust?

Rust occurs when an iron-containing material is exposed to moisture. When the two substances come into contact with each other and react, oxidation is produced. The most common cause of rust in your car is rain.

How long does it take for Rust to form on a Car?

There is no set age for a car to rust. Over time, corrosion and wear damage the protective coating, exposing the metal to moisture.

Causes of car rust:

  • Climate: Regular exposure to rain, sleet, and snow increase your vehicle’s metal oxidation. The salts used to grind icy roads can also speed up erosion. Conversely, higher temperatures also contribute to higher corrosion rates.
  • Vehicle Life: Over time, protective vehicle coatings will wear out. If metal surfaces are exposed to moisture, they will eventually rust and corrode.
  • Manufactured materials: Old cars were made without protective coatings, making them more susceptible to rust wear. On the other hand, manufacturers are working today to develop materials and products for cars to prevent damage.
  • Driving style: If you are one of those who tend to drive off-road, know that your car will wear out more quickly.

Car rust flakes off when left on the surface for a long time untreated and enough to corrode the metal on the body panels.

Cause of car rust

Types of car rust

There are three types of rust:

  • Surface rust affects the upper layer of your car and results in bumps, scars, or bubbles on the car panels. Treating the damage at this point is very helpful to prevent rust from spreading to the rest of the vehicle.
  • Peeled Rust: This occurs when rust is left on the surface for a long time untreated, enough to corrode the metal on the body panels. Road salts speed up the corrosion process and can affect the integrity of the metal itself.
  • Deep Rust: It is the most advanced type of rust and the most harmful to the car. If peeling rust develops, you may need to replace the entire body panels.

Common Car Rust Locations

The most important thing to look for while rust proofing your car is the presence of bubbles in the car’s exterior paint. These bubbles are early tell-tale signs of rust.

Besides looking at the bodywork, there are a few other areas you should pay extra attention to while rust proofing your car. Check out these parts on the bottom of your car:

  • The chassis – otherwise known as the car’s chassis, look under the sides of the vehicle under the doors.
  • Wheel Compartment – The curves above your tires are prone to rust, especially on older cars that usually don’t have arch bushings.
  • Exhaust – Exhaust is exposed to moisture inside and out as it becomes covered in mud and dirt.
  • Suspension – tends to contact moisture due to its proximity to the tires and can get dirt under the car.

You should also make sure:

  • Car Floor – Lift the car floor mats and make sure there are no signs of rust.
  • Window surrounds – Make sure the areas around the windows or windshield are more exposed to moisture than others.
  • Doors – Check the doors from the inside and outside of the car.

  • Scratches – look for dents because they rust if not treated.
  • Harmful paint – caused by personal rust maintenance; if not suitable and effective, rust may reappear.
