As professionals in the field, we’re here to guide you through the process of addressing rust spots effectively, ensuring your vehicle leaves our shop looking and performing its best. In this comprehensive guide, we’ll cover everything from understanding the causes of automotive rust to the step-by-step repair process, including how to prevent rust from coming back. We’ll also explain why it’s best to trust a professional body shop for rust spot repair.

Small rust spots generally are indicators of a deeper issue. If you leave surface and scale rust to develop, you might need to replace entire parts and body panels. Large-scale rust repairs become necessary when the metal has started to corrode completely through, which will eventually weaken the integrity of supporting structures enough that they may not be able to withstand a subsequent collision.

Why do Cars Rust? The Root Causes of Automotive Rust

To effectively tackle rust, it’s crucial to understand what causes it. Rust is the result of a complex chemical process primarily driven by three factors:

1. Iron Oxide (Rust):

Rust, scientifically known as iron oxide, is the visible product of the corrosion process. It forms when iron (present in steel) reacts with oxygen and moisture. This chemical reaction gradually weakens and deteriorates the metal.

2. Sheet Metal and Base Coat:

Automobiles are constructed with various types of metals, with sheet metal being one of the most common. Sheet metal is used for body panels, and it's especially prone to rust due to its exposure to the elements. The base coat of paint on your car acts as a barrier to protect the metal from moisture and oxygen.

3. Moisture and Oxygen:

Moisture, often in the form of rain, dew, or even humidity, plays a significant role in rust formation. Oxygen is readily available in the air, and when it combines with moisture and comes into contact with exposed metal, it triggers the corrosion process.

Now that you know what causes rust, let’s proceed with the step-by-step process of addressing rust spots.

Identifying Rust Spots: Where to Look

Surface rust or something worse?

Rust is notorious for hiding in inconspicuous places on your car. To effectively tackle rust, it’s essential to know where to look. Surface rust is usually a telltale sign of deeper issues. Here are some common areas to inspect for rust:

1. Wheel Wells

Start by examining the wheel wells and the surrounding areas. Moisture and debris can accumulate here, making it a prime location for rust to develop.

2. Rocker Panels

Rocker panels, located along the lower sides of your car, are highly susceptible to rust. They often get exposed to road salts and moisture, making them a rust-prone area.

3. Undercarriage

Don't forget to check the undercarriage of your car. Rust can start from the bottom, especially if you frequently drive on salted or gravel roads. Road salt, commonly used to prevent icy roads, is especially damaging to the metal underneath your car.

4. Body Panels

Inspect the body panels, including the doors, fenders, and trunk. Pay close attention to areas around the edges where moisture can accumulate.

5. Paint Bubbling

Paint bubbling is often an early sign of rust underneath the paint. If you notice bubbles or blisters on the surface, investigate further.

What We Recommend for Tackling Rust on Your Car:

It’s possible to tackle rust repair yourself. Sometimes it’s not within the budget to hire a professional body shop to do your repair work, and that’s ok.

Note, however, that the results will vary depending on your preparation and skill level.

Before tackling any rust repair work, it’s important to gather all the right tools and materials. Here’s what we recommend:

Step-by-Step Professional Rust Repair:

At Mizzoni’s Auto Body, our team follows a meticulous process to address rust spots effectively:

Safety is paramount. Our technicians wear safety goggles, gloves, and dust masks to protect themselves from rust particles and chemical fumes.

We assess the rust spots to determine their extent, differentiating between surface rust and penetrating rust. This evaluation informs our repair strategy.

We use wire brushes to remove loose rust, paint, and debris from the affected area, ensuring it’s clean and dry.

Often we use a car wash soap to ensure a particle clean surface.

For penetrating rust, we apply a rust converter per the manufacturer’s instructions to halt further corrosion chemically.

For surface rust, we gently sand away the rust until we reach bare metal. For penetrating rust, we sand the area after applying the rust converter to smooth it over and get all the small rust spots out. It’s absolutely critical to get down to the clean metal underneath before moving on to primer and paint.

There are times when there are large areas that cannot be salvaged. In that case, we will need to use an angle grinder to cut out the damaged body panel and make sure all the rust is completely removed.

An automotive-grade primer is applied to the sanded area, creating a stable foundation for the paint and preventing future rusting. The primer must be dry before moving on to the painting process.

We custom-match the paint to your car’s specific paint code, ensuring a perfect blend. Multiple coats may be applied, allowing each coat to dry between applications.

For deep rust spots, we use body filler to fill holes and uneven surfaces, ensuring a seamless appearance. If you have a rust inhibitor that is safe to use with body filler, add this now, but otherwise, you can seal your work with a regular, high-quality primer.

Once the paint is dry, we apply a clear coat to safeguard the repaired area and provide a glossy finish.

We remove masking tape and paper, and our technicians perform a final inspection. We ensure the repaired area is free from dust and debris.

Stop Rust As Early As you Can

We recommend addressing rust spots as early as you can spot them. The sooner you remove rust, the better. It will only get worse, so a proactive approach is the best approach when it comes to addressing a rusty area on your car.
