Rust on cars will appear sooner or later. For this reason, it’s essential to know how to fix rust on a car. Dark brown stain on the fender; a blob of paint at the base of a door. These are indications of rust. Otherwise, good cars are commonly dumped early because they rust. Despite the fact that it is typically avoided.

Learn how cars rust, where the problem areas are in your car, and how car rust may be repaired.

What Causes A Car To Rust?

The planet’s surface has an abundance of both water and oxygen, making it a common component of our biosphere. Steel that is exposed to air will soon rust owing to a process known as oxidation. However, certain steels rust more slowly than others. Furthermore, new cars are made of significantly more durable galvanized steel, a highly corrosive material.

The paint on your car is also important in preventing rust damage. It effectively keeps oxygen and water from entering the steel beneath its surface.


In general, as long as you consistently clean and care for your car, you shouldn’t have to worry about rust. However, if you have an old car that you want to restore, or if your vehicle has rust from being left outside for months, there are ways to treat the oxidation without replacing the steel entirely.

5 Easy Steps To Fix Car Rust

Mask the region you’re treating

Protect everything surrounding the rusted area you wish to eliminate using masking tape and newspaper. Allow a few inches between the border of the spot and the beginning of the mask. Spray primer and paint mist may go a long distance in the air.

Take Off the Paint Around It & the Rust

Sand the rust and the paint around it to the bare metal using sandpaper, a sanding block, or a power sander, depending on the level of the rust. If you need to fill a rust hole, first paint the area surrounding the hole with an etching primer and allow it to dry. Then, according to the package directions, mix the body filler and fill the hole. Contour it into the shape of the body panel as best you can. Leave it to totally dry.

Sand the area and use primer 

Smooth the area using 150 grit paper. It might be preferable to sand 2 times.  Wipe away the dust and dirt from the sanded area. When it’s dry, add a thin coating of paint primer, let it dry, then sand it smooth using grit paper. Repeat the primer/sanding procedure as many times as necessary. Sand the surface once you’ve finished your last application. When finished, wipe the area free of dust and dirt.

Paint the Location

Apply the paint once the area is clean and dry. Apply small layers to avoid paint buildup. Allow the paint to dry before sanding with grit paper and cleaning the area. Three times through the painting/sanding/cleaning procedure.

Put the Clear Coat on

Apply the clear coat according to the directions after the area is clean and dry. You can use a similar process to repair minor scratches on your vehicle’s body too.

How To Prevent The Formation

The good news is that this type of vehicle deterioration is largely avoidable. The most apparent piece of advice is to wash your car on a regular basis to maintain the body and bottom free of road grime, salts, and dirt that cause corrosion. Many contemporary car washes can blast the bottom of your vehicle with water to remove a lot of the filth.

Inspect the drain holes at the bottoms of doors and rocker panels, which enable rainwater to drain. Clear these holes using a pipe cleaner and keep the car’s nooks and crannies dry. WD-40 might also be effective in this situation. This lubricant prevents parts from corrosion, and its small nozzle may be used to blast away water or corrosive filth from tight underbody locations.


As you can see, repairing substantial rust on your vehicle is possible if you have the correct equipment for the job – and a little patience. You don’t have to undertake extensive repairs to restore your car to its pre-rust condition. If you follow this advice, you’ll be able to effectively tackle any significant rust removal operations.
