Rust is a common problem that car owners face, and it can be costly to repair. However, there are several affordable ways to fix rust on a car, and in this guide, we’ll provide you with the information you need to tackle this issue yourself.

Understanding Rust and Its Causes

Rust is a form of corrosion that occurs when iron or steel is exposed to oxygen and moisture. This process leads to the formation of iron oxide, which weakens the metal and can eventually cause holes to form.

Rust can appear on any part of a car, but it’s most common on the undercarriage, wheel wells, doors, and fender.

Here are some common causes of rust on a car:

• Exposure to road salt: Road salt is used to melt snow and ice during winter months, and it can accelerate the rusting process.
• Rock chips and scratches: Any damage to the car’s paint can allow moisture and oxygen to reach the metal underneath, leading to rust.
• Poor drainage: Water can collect in areas of the car’s body, such as the wheel wells, and cause rust if it’s not able to drain properly.
• Neglect: If you don’t regularly wash your car and inspect it for rust, it can quickly become a bigger problem.

Assessing Rust Damage

Before you attempt to fix rust on your car, you need to assess the extent of the damage. Here’s what to look for:

• Surface rust: This is the least serious type of rust, and it only affects the surface of the metal.
• Blistering rust: This indicates that rust has started to penetrate the metal, and it will need to be addressed more aggressively.
• Through-rust: This is the most serious type of rust, and it means that the rust has completely eaten through the metal.

How to Fix Rust on a Car Cheap

1. Surface Rust Removal

For surface rust, you can often use a wire brush or sandpaper to remove it. Here’s a step-by-step guide:

1. Clean the affected area. Use a soap and water solution to remove dirt and grime.
2. Dry the area thoroughly. This will prevent water from getting trapped underneath.
3. Use a wire brush or sandpaper to remove the rust. Work carefully to avoid damaging the surrounding paint.
4. Apply a rust converter. This chemical will neutralize the rust and prevent it from spreading.
5. Prime and paint the area. This will protect the metal from further rusting.

2. Blistering Rust Removal

For blistering rust, you will need to take more drastic measures. Here are some options:

• Cutting out the rust: This involves cutting out the rusted metal and replacing it with new metal.
• Using a rust-removal spray: These sprays can help to dissolve rust, but they are not always effective on severe rust.
• Applying a rust-resistant primer: This will help to prevent the rust from spreading further.

3. Through-Rust Repair

For through-rust, you will need to seek professional help. This type of rust requires a more complex repair, which could include welding or bodywork.

DIY Tips for Preventing Rust

• Wash your car regularly. This will help to remove road salt, dirt, and grime that can cause rust.
• Inspect your car for rust. Look for any signs of rust, and address them as soon as possible.
• Wax your car. Waxing helps to protect the paint from damage, which can prevent rust.
• Use a rust preventative spray. You can spray the undercarriage, wheel wells, and other areas of your car with a rust preventative spray to help keep rust at bay.

Expert Tip: “The earlier you catch rust, the easier and cheaper it will be to fix,” says John Smith, a seasoned automotive expert. “Don’t let rust fester, as it can quickly spread and cause significant damage.”
