First, let’s discuss the moment when cars begin to rust.

To be honest, you can’t pinpoint exactly when rust starts to set in. No, you can’t really tell that at this specific age that your car will begin to rust.

However, as time passes, your car will undergo the normal wear and tear can of things. Eventually, the protective coating diminishes. The automotive refinish gets exposed to the moisture in the air.

Older car models were manufactured using materials made of rust-proofing components. At the end of the day, car rust depends on the following factors beyond your control.

The causes car rust.

Before I begin, you should know that rust develops when iron is exposed to oxygen and water. When this happens, you will notice that a brownish coat will start to appear. Once it spreads, this mix of red and brown coat will gradually lead to corrosion.

Here are the common factors that will contribute to the rust on your car:

  • Age – The #1 factor to consider is the age of your car. Of course, the paint along with its protective film will eventually fade. If the bare metal is out in the open, oxygen and water can set in, and rust will start to develop.
  • Specific components – Know that older vehicles are made with less top-of-the-line materials. Today, with the advent of technology, the cars now have better materials that can prevent potential damage including rust and corrosion.
  • Weather conditions in your area – If you live in a place where there’s constant rain and snow, this will contribute to the eventual damage. You will have more chances to experience rust on your car. Salts are used to sand the icy roads so that it will be less slippery, but salts can hasten the corrosion process.
  • YOU – Whether you admit or not, your driving style can aid the development of rust. If you aren’t careful, you will increase the risk of corrosion. So, be careful when passing through puddles and other road bumps.

What are the types of rust?

Here are the common type of rust that you will see in most vehicles:

  • Surface rust – As the name suggests, this will only damage the top layer. You will notice this type of rust on the body panel. It is important to start treating the rust immediately. At this stage, you should work on it to prevent the spread.
  • Scale rust – When you ignore the surface rust long enough, it will eventually corrode. Moreover, the salts found on the road will speed up process.
  • Penetrating rust – Lastly, the rust with the most damage is the penetrating rust. If this happens to your car, you will need replace the entire part, and not just a tiny portion of the body panels.
