An alarming dark stain can be seen on the fender. The bottom of a door has a paint bubble surrounding it. The floors were saturated after tripping into a puddle. Rust indicates that the iron worm has been busy. Get away from it. Rust, on the other hand, will appear.
Despite the numerous coatings and alloys created by chemists and engineers, iron’s chemical constitution means it will always rust in a natural environment. Iron and most steel, in fact, will completely disintegrate into iron oxide and other constituent components given enough time. This does not indicate that you are unable to operate your vehicle!
What Causes Your Car to Rust?
When iron-based metals undergo electrochemical breakdown, rust is generated. This breakdown is caused by the oxidation process, in which iron surface molecules react with oxygen in the environment to form Fe2O3, commonly known as iron oxide. Iron oxide is the main component of rust.
Exposed steel rusts at different rates based on the alloy components, thickness, environment, and type of heat treatment it undergoes. There’s also the salt effect to consider. Impurities in water, such as road salts and other contaminants, are known as electrolytes. The exchange of molecular components is increased when electrolytes are introduced to a chemical process.
Although adding alloying metals such as nickel and chromium to automotive steel might help prevent rust, nothing is fool proof everything corrodes eventually. When it comes off the roll, modern sheet steel also has extremely durable coatings. These effects are increased at final assembly factories, where newly constructed vehicle bodywork is immersed in anti-corrosion chemical baths before being painted.
Types of Rust
Surface Rust
Surface rust on your automobile happens when the paint breaks down due to mechanical or UV damage, which is why it may happen even in hot, dry weather. Surface rust is not a structural problem, and depending on the metal thickness and alloy composition, a level of “passivation” can be attained in which the surface rust actually shields the metal from further oxidation.
Scale Rust
If you don’t treat surface rust and allow the breakdown to move further into the metal, you may see bubbles emerging in your car’s paint. Because iron oxide molecules are physically bigger than iron or steel molecules, this is the case.
Rust entering through the surface in this way causes scale, which is a rough, pitted type of corrosion. Scale can be removed with a wire brush to remove rust, a grinding wheel to reduce roughness, and sandpaper to smooth the surface.
Penetrating Rust
Rust seeping through the surface in this way causes penetrating rust scale, which is a rough, pitted kind of corrosion. Scale can be removed with a wire brush to remove rust, a grinding wheel to reduce roughness, and sandpaper to smooth the surface. Do not attempt to rebuild the frame of your automobile.
What Is the Best Way to Prevent Rust?
The best piece of advice is to wash your car on a regular basis to prevent road dust, salts, and dirt off the body and undercarriage, which promote rust. Many contemporary car washes use water to blast dirt off your vehicle’s undercarriage. Rainwater can be drained through drain holes on the bottoms of doors and rocker panels. Using a pipe cleaner, clean the holes and keep the car’s nooks and crannies dry.
As with other rust repairs, sand off any rust that may be sticking through and rough up the area you want to paint with sandpaper, then brush or spray on the fresh coating. If you maintain it properly protected from the elements and free of hazardous salt and dirt, you should be able to get years of safe driving out of even the most damaged winter beater.
