How To Stop Rust On Your Car

5 Ways To Stop Rust On Your Car: The Best DIY Solutions


It’s essential to know how to stop rust on your car if you’ve recently bought one because rust is probably inevitable, and it’ll catch the metal parts of your car if you don’t put effort into stopping it.

The best way you can stop the rust on your car is by washing and waxing it regularly. Moisture reacts with metal and forms rust, so if you regularly wash your car, dry it, and then wax it, your car will be away from rust for longer.

This way applies if you’ve recently bought a new car and want to keep it from rust. If your car has been old and has rust on its some parts, then this only way might not work, and you’ll need to follow some more ways that you’ll learn about next.

Best Ways To Stop Rust On Your Car

There are 5 best ways that you can follow to prevent your car from rust. All these ways are practical, and they never fail to work-

1. Wash Your Car Regularly

Washing a car is the most common task, and it must be done regularly. It not only keeps the car rust-free, but it also makes it look new and shiny for longer.

From washing here, I don’t mean just to pour some water on your car and then wipe it off with a piece of cloth because that takes only a few minutes to do and has no effects on the rust. Washing means washing your car with a good quality car shampoo that leaves no streaks, dirt, and debris behind.

After washing the car, it’s essential to dry it by wiping it with a microfiber cloth. Most people just wash the car, and then they leave it to dry itself, and that causes the water to stay on the metal parts for longer, which results in rust. This may also cause the paint of your car to bubble and rust.

I recommend using a microfiber cloth because it absorbs the water completely and is gentle to the glass material.

Also, don’t forget to clean the interior of the car. The interior of the car also has some metal parts that start to rust if not cleaned regularly. You can use a glass cleaner to clean the dashboard, steering wheel, key ignition, windshield, and glass window. This 10-minute work won’t only prevent the interior parts from rust, but it’ll also make it look shiny and new.

2. Don’t Forget To Wax It

Waxing protects your car paint and works like rustproof, and most people skip doing this after washing their car.

A good quality wax protects the car’s paint because it covers the paint, which saves the paint from moisture retention that causes the paint to bubble out and rust.

Waxing prevents the car paint from rust and oxidation, making the car look new and shiny for longer.

Always ensure to wax your car after washing and drying it. Some people make the mistake of applying the wax just after washing and wiping their car, which causes the wax to mix with moisture and leave spots behind. Leave your car for at least 10 minutes to air dry after washing and wiping it so that there’s no moisture left on the car. Once the car is completely dry, get the wax and apply it to the car.

3. Check Your Car Thoroughly For Rust

It’s essential to check your car’s interior and exterior parts at least once every ten days for any rust or corrosion. If you find any bubbles on the paint or small spots of rust on any part, fix it immediately because the rust starts to spread faster.

In most cases, the rust is found on the bottom of the bumper, wiper blades, and screws in the initial days of buying, so it’s important to take a look at these components regularly.

Also, don’t forget to pop your hood and check the important internal parts such as the battery and engine for any rust or corrosion. These parts are essential, and rust or corrosion can lower their performance if not addressed immediately.

4. Fix The Minor Rust

Minor rust is supposed to be treated immediately to be prevented from expanding. Here are the steps that you require to follow-

Clean The Rusted Area

First of all, clean the affected area using car shampoo and water. It’s essential to free it from any dirt and debris so that when you apply anything on it to cover the rust, it gets to all over that area.

Cover Surrounding Area

Use a painting or masking tape to cover the surrounding of the affected area so that when you apply anything on it, the area which is fine doesn’t get affected.

Remove The Rust

Use a razor blade to remove the bigger rust flakes first. It’ll make it easier to remove the small particles of rust.

Sand The Rusted Area

Sand the affected area thoroughly using 40-60 grit sandpaper. It’ll help to remove the small particles of rust from that area.

Apply A Rust Arrestor

Rust arrestor consists of the chemicals that hold the property of preventing the rust from occurring again. Apply a thin coat of rust arrestor to the affected area using a brush and then let it dry for 25-30 minutes.

Apply A Primer

Once the rust protector has been completely dried, apply a thin coat of primer. Primer fills the holes and scratches of the affected area and makes it ready for paint. After applying the primer, leave it for 30 minutes and then apply the second coat. Once you’ve done applying the second coat, leave it for 1 hour so that it dries completely.

Apply The Touch-up Paint

Once the primer is completely dry, apply the touch-up paint to it. Make sure you’re using the correct touch-up paint for your car. If you don’t know where to buy it, use the code next to your VIN to buy the accurate touch-up paint from any local automotive or dealership store.

So this is how you fix the minor rust. Next, you’ll learn how to fix the major rust.

5. Fix The Major Rust

The major rust is the result of not addressing the minor rust. The major rust requires more work to be fixed because it’s severer and wider than the minor rust. Here’s the step-by-step process of how you fix it-

Cover The Surrounding Area

Just like you need to cover the surrounding area with masking tape in minor rust, you’ve to do the same thing here in the case of major rust before treating the affected area.

Put On Safety Gear

Treating major rust is more intense than treating minor rust, so it’s essential to get equipped with safety gear such as protective eyeglasses, a gas mask, and protective gloves before heading to fix it. These safety gear ensure to keep you safe from all the possible mishaps.

Remove The Rust Flakes Using A Grinder

It’s pretty impossible to remove the bigger rust flakes using a razor blade in the case of major rust, and that’s the reason you’ll need a grinder to remove it. The grinder removes the rust flakes and cleans the affected area quickly, making the whole process easier.

Clean The Affected Area With A Sandpaper

Use 40-60 grit sandpaper and sand the affected area thoroughly. It’ll help to make the affected area cleaner and smoother.

Remove Rust From The Backside Of The Rusted Area

To prevent the same area from rusting again, you’ll need to remove the rust from the backside of the affected area to prevent it from expanding and affecting the same area that you are repairing. To clean the backside, use sandpaper and sand it until it turns into sheet metal. You can also use the grinder to remove the rust if you find it convenient to do.

Coat The Backside Of The Affected Area

Apply a thin coat of rubberized coating to the backside of the affected area to prevent it from rusting again. As nobody will see the backside, you don’t need to coat it with primer or touch-up paint.

Apply The Fiberglass Filler To The Affected Area

Mix the fiberglass filler with the hardener and then apply an adequate amount to the affected area. The fiberglass filler fills the patches, making the affected area look normal. Make sure the affected area is covered with it well.

Sand The Affected Area Again

Once you’ve applied the fiberglass filler, sand the affected area again to make it even with the surrounding areas. You’ll need 180-200 grit sandpaper for this step because you’ve to give it a seamless finish, which is probably impossible to do with a 40 grit sandpaper.

Apply The Primer

Now, as you’ve made the affected area smoother and even, apply the primer to it. Now, as this area is bigger, you’ll need to apply three layers of coating of the primer to make it look smoother. After you’ve done applying it, let it dry for at least 1 hour.

Apply The Touch-Up Paint

Once the primer is dry, apply the touch-up paint to it. Now, if you’re not sure you can do it yourself, get to a professional and get this process done. I’ve already mentioned where you can get the touch-up paint for your car.

Apply The Clear Coat

This is the final step of this whole process. In this step, you’ll need to cover the painted area with a clear coat. Clearcoat gives the painted area extra shine that matches the surrounding areas. Now leave it for 1-2 hours so that the clear coat completely dries, and then wash the area with car shampoo and water. You’re done.

So this was all about dealing with major rust. If the major rust isn’t fixed immediately, it can cause to replace the rusted part with a new one. So make sure you fix it before it gets worse.

What If You Don’t Stop Rust On Your Car

If you don’t do anything about stopping rust on your car, your car’s life span will shrink, and the exterior part of your car will be looking like junk. The car’s value also gets deprecated, and no one’s ready to pay good money for your car if you ever want to sell it.

It also costs expensive to get your car free from rust after it has covered most of the car parts because that requires your car to go through many processes and use expensive materials.

So it’s essential to keep your car with proper care and prevent it from rust from the initial days.

Benefits Of Stopping Rust On Car
