How to stop rust on car frame

Are you wondering how to stop rust on car frame? Has your car started accumulating rust, and you don’t know what to do? If yes, then you have come to the right place.

Getting rust on your vehicle is a serious issue that you should not avoid. Rust not only diminishes the look of your car but also lowers its market value.

In simpler words, rust is a silent car killer, which, if not treated on time, can cause major issues in your ride and ultimately make it unfit to use.

By not taking proper care of your ride, you are setting it up for failure. Actions like continuously exposing it to rainwater, no adequate cleaning & maintenance routine, and no professional outlook are prime reasons for rust formation.

But the good news is that this whole scenario can be prevented. You can not only prevent your car from rusting but also eliminate any rust formation on your car.

To help you get started, we bring you this easy beginner-friendly guide. Here we have discussed types of rust, causes of rust formation, how to stop getting rust on the car frames, and more. So, let us get started and help you take better care of your ride.

What Is Rust?

We need to understand the basics before learning how much frame rust is too much. Rust is the combination of oxygen and iron, mainly known as “Iron Oxide.”

It is formed as the result of the chemical reaction when iron or any material that contains iron, like steel, is exposed to water & air for a prolonged period.

First, the moisture on the iron surface mixes with the carbon dioxide in the air to create a weak acid that begins to dissolve the iron.

At the same time, the remaining water component is also getting broken down into hydrogen and oxygen elements. And out of these two separate elements, the oxygen atoms combine with the iron atoms and form iron oxide.

Iron oxide is red in color. It seems like the red dust is standing on your car’s surface. It is why rust is also referred to as “Red Dust.”

Types Of Rust

Rust is deadly for your vehicle. But it does not automatically go to the stage where it is impossible to recover your car. Rust on vehicles happens in stages. It means if you do not take care of the problem when it begins, it will continue to progress and do more damage.

But how to tell if the rust formation on your ride is just the beginning or if it is way past the phase that you can handle? All this confusion can be resolved if you know the different types of rust formations.

Here we have all types of rust that can form on an automobile. Let us check them out:

– Surface Rust

You will encounter a surface whenever your car’s paint breaks down. Vehicle paint breakdown generally happens with prolonged exposure to the sun’s harmful UV rays or due to mechanical damages like dents, scratches, or scrapes.

The paint breakdown exposes the metal surface to air, leading to rust formation over time. The good thing is that surface rust is only the beginning and can be easily removed.

You can use an abrasive wheel or high-grade sandpaper to grind it down until the rust from the affected area is gone, and the shiny metal beneath is exposed. After this, with the help of a car polisher, you need to prime the area and apply new paint.

– Scale Rust or Bubble Rust

When the surface rust is left untreated, it often forms scales, also known as bubbles. This situation arises when the surface rust expands and flakes, exposing the metal surface underneath.

At this rust stage, the metal begins to corrode, and the rust continues to go deeper and thus creating scales. This intermediate rusting state can be treated by adequately grinding the rust from the infected area.

However, in this stage, you will require more strength and even a handy tool like a wire brush to go deep into the rough scales before the grinding.

– Penetrating Rust or Corrosion

If you leave the scale or bubble rust untreated for a long time, the metal will weaken more, and the rust will leave holes in your car. This is the most brutal rust stage, and you have few options to fix this problem.

In maximum cases, you will require to replace or cut out the area affected by the rust and have patch panels welded in its place.

And corrosion is an even bigger problem if it is on the frame of your car. The structural integrity of your vehicle gets compromised, making it unsafe for you to drive. So, answers to questions like how to remove rust from car frames are complex.

What Are The Main Causes Of Rust On A Car?

Iron is a vital element that is hard to break by external force. But it becomes the weakest due to its own rust. There are several reasons why rust formation begins on an iron surface.

It is prevalent in automobiles, especially the ones that are not taken good care of. Car owners often claim to follow a good maintenance routine but still find their ride with rust budding in various parts.

how much frame rust is too much

If you are among such car owners, then before exploring how to fix rust on a car frame, you need to learn what is causing it in the first place. Many factors are at play for an automobile to catch rust. Here we have listed the most common ones for you:

A. Climate

The biggest culprit for your car getting rust is the climate. Your vehicle gets regularly exposed to rain, snow, hail, and sleet. This frequent exposure increases the chances of moisture sitting on different areas of the car and oxidizing with the present metals.

B. Salt

Vehicles are the mode of commute. And thus, they get exposed to road salt numerous times a day. Road salt is usually laid on the road to lower the freezing point of water. But it can harm your car components by rusting them.

The salt acts as an electrolyte. It permits the iron components of your ride to lose electrons quickly, thus causing rust formation. This high exposure to road salt is generally restricted to the surface beneath your car.

C. Car Age

The paintwork and protective coating on your ride degrade with time. If this degradation is not appropriately maintained, the metalwork beneath gets in contact with the moisture, leading to rust formation after prolonged exposure. Also, the older the car or its paint job, the more it is prone to rusting.

D. Car Material

The materials used in building a car play a massive role in rusting. Earlier, cars were usually made without non-reactive coatings. This made them more vulnerable to rusting.

But this is not the case with most modern cars that come with those non-reactive coatings that ensure that no such thing happens to a great extent.

E. Driving Style

How and where you drive your vehicle also decides the rusting chances of your car. If you drive primarily off-road and on muddy terrains, your ride has more risk of catching rust, even with proper maintenance.

F. Negligence

One of the most common reasons most people get rust on their cars, even on the new ones, is their absolute negligence towards them. You must maintain your ride correctly to ensure its good health.

What Are The Most Common Rust Locations In A Car?

Rust formation can take place in any part of your car. However, a few locations are more prone to it than others. Many car owners think that the surface of their ride is what gets exposed, and thus it is the only place to get rust. But it is not always true. Often, the rust begins inside part of your car & makes the way outward.

So, if you see surface rust in your car and get rid of it, do not be happy so soon. Check beneath the surface and ensure there is no rust buildup inside the body of your car.

Thus, before searching for how to stop rust on a Jeep frame or any other ride you own, learn about the most common areas to inspect.

1. Frame Rails

The frame rails run underneath both sides of your vehicle under both doors. These are generally made of steel channel sections.

2. Exhausts

The tailpipe of your ride is exposed to moisture all the time from the inside out. Thus checking it regularly will let you know the rust status.

3. Wheel Walls

These are curves above your tires. They are also highly prone to rust, especially in older cars that do not come with arch liners.

4. Suspension

The suspension of your ride is highly prone to get in contact with moisture as it is close to the tires, which flick up dirt and all kinds of debris.

Most people ignore the lower surface of the car, which has a higher chance of rust formation. So check the suspension every time you clean your ride, as it hits your car frame the most.

5. Windscreen

The areas around your car windshield are prone to leaking and can expose the nearby area to moisture. The leakage is so negligible that most of us can not spot it. And with time, it leads to rust. So, always check your windscreen for any leak, mainly on the sides.

6. Boot Floor

We all have car floor covers inside our cars to make the interior look more classy and comfortable. But this cover sometimes keeps us from learning what goes beneath the surface. So, make sure to pull up those carpets every now & then and look for any signs of rusting.

7. Car Doors

Doors tend to capture the water at their edges, especially when it’s raining and you take time to close them. So, always check them inside & out during every rust inspection.

Exposure to road salt is one of the primary reasons for rust formation. So, if you have rust coating in areas frequently exposed to salt, rust coating can be an absolute game changer. If your car is expensive or you wish to keep your ride long, this is a must-step.

5. Park Indoors

For your vehicle’s long life, you need to protect it from the outside elements. The constant exposure to the sun, rain, snow, and other elements can hurt your car more than you can imagine.

So, try to always park your ride indoors. If you are outside, try to park it in shades. Keeping your ride in your house garage or inside parking will keep it safe from scorching UV rays, hail, heavy rain pour, and more. If you do not have a garage, you can purchase a portable one, an affordable option.

6. Avoid Driving In Rain

Try to avoid driving during heavy rainfall. It is because acid rain is a real thing. The components of acid rain can quickly get deposited on your car’s surface and damage it. And there are chances it can make its way to the inside of your vehicle.

But there are times when you may not avoid driving in the rain. At those times, you should wash your ride as soon as you return home. Washing your ride with a tap will remove all the harmful rain chemicals from the surface.

They will keep your car’s surface safe from outside contaminations. But to ensure you get all the benefits, try to purchase the cover from a reputed maker.

The more durable and breathable the product is, the better it will take care of your ride. Also, a quality cover will allow the humid air to escape, eliminating the high chances of rust formation.

8. Install Mudguards

When driving, especially on a muddy road, the chances of your wheels and brakes getting exposed to contamination increase.

To avoid this, you can install mudguards on your ride. They eliminate unnecessary water contact on the bottom surface of your ride.

Driving on surfaces filled with water or mud hurts your brakes significantly. But having good quality mudguards ensure no harm is done.

9. Avoid Parking In Humid Areas

You should avoid parking your car in enclosed areas with high humidity. This is not good, especially if your vehicle already has rust formation. So, if you find your house garage has humid air, take care of it first, then park the car inside.

10. Plan Your Driving Route Beforehand

You should always plan your route before you take your ride out, especially during the rainy season. Avoid the roads that are most likely to be flooded with water. And if the situation is worse, you can always opt for a taxi service.

11. Clean The Drains

All the vehicles have drains around their bodywork in different locations. They are essential as they let the water run away in areas prone to rusting.

However, debris can sometimes enter these drain holes and block them up. The water sitting inside your car for a long time will lead to rust formation.

So, check for all the drain holes in your ride and clean them to ensure there is no blockage. The bottom of car doors, tailgates, and bumpers are where the drains are usually located. But to be sure, refer to your car’s owner’s manual.

12. Wash The Underside

Pay attention to the underside of your car. The bottom of your vehicle comes in contact with all kinds of dirt and debris. If you do take care of the underside, the settled dirt & debris will lead to rust formation over time and kill the structure of your ride.

So, use underbody spray to get every last particle of grime out from the base of your ride. To ensure more safety, seal the underside with chassis rust removal spray that resists all the corrosive elements and does not let them sit on the surface.

13. Tackle The Rust Immediately

If you find any scratches, swirls, or rust formations anywhere on your ride, tackle it immediately. Do not let the ruined paint job sit there for long. If the paint job coating is damaged, apply a new one to protect the area.

And if there is rust formation, no matter how small, use your car maintenance kit to remove it. Make a habit of checking all the places of your ride with a torch after cleaning for any molding, scratches, damaged paint job, and more.

The sooner you find & handle the issue, the better. Several best tools for removing rust from frames are available in the market. With little research, you can find the best product for your usage.
