Difference Between Rust And Corrosion
Rust and corrosion are often used interchangeably. While they are connected, they dont mean the same thing and it is important to understand the difference between the two. They are both an electrochemical process that results in oxidation, but the difference lies in the types of objects and materials that each of them affects.
The main difference between rust and corrosion is that rust is a type of corrosion. Corrosion is a catch-all, umbrella term for the deterioration of materials due to exposure to carbon dioxide and oxidation. This is also sometimes called green rust. It can affect almost any kind of surface including non-metals like ceramics and polymers. It also requires exposure to air or other chemicals, whereas red rust, which is what we typically think of when we think about rust on cars, needs a combination of exposure to oxygen and moisture to form on metal surfaces.
Inspect Thoroughly For Early Detection Of Rust
Another important way to stop rust on your car is to inspect for rust. Try to identify all the spots where rust can find its home. The exterior surfaces indicate the presence of rust when you see blisters or bubbles on the paint. The blisters and bubbles are usually an initial stage of the commencement of rust. Advanced rust, on the other hand, has a reddish-brown color and displays a flaxy texture. Advanced stubborn rust often damages the car surface at an incredibly fast rate and, if not stopped, causes irreversible damage.
The other two areas that are most susceptible to rust include the undercarriage as well as the car engine. Use a flashlight for the inspection, so it is easier for you to identify the rusty parts. Always remember to inspect the wheels, side-mirror connection points, the antennae, drain holes, and other places where body components meet. Remember that if you do not identify rusty spots early enough, it may cause irreversible damage to the affected area, and you may have to replace the whole part immediately with a custom made one.

Wash Your Car On A Regular Basis
If you want to stop rust from starting or spreading, then you have to make it a habit to wash it on a more regular basis. It goes without saying that washing your car should always entail a very thorough drying of all moist or wet parts. Moisture thats left on any metallic surface on your car has the potential to cause rusting.
It is important to understand that dirt and dust will not cause corrosion. However, these can rub against the protective paint of the car. Car paints are not that thick. With constant friction with road debris, this thin layer of protective paint can also wear off. When that happens, then you are inviting the development of corrosion.
Bird droppings may seem like benign organic matter. But the organic compounds present in these animal wastes can also cause a chemical reaction on the clear coat of the car. The same is true with automotive fluids like brake fluid, automatic transmission fluid, and fuel, among others. If any of these fluids spill onto metal parts of the car, then theres a chance that corrosion can take place.
Of course, the rusting we are talking about will develop over time, not overnight. Having said that, cleaning your car and washing it every week is ideal. This is to help remove any dirt, sand, and road debris that may accumulate in hard-to-reach areas like wheel wells. The inner side of the bumpers as well as the underside of the car are also areas that you have to wash in a very thorough manner.

How Does Nh Oil Undercoating Work
NH Oil Undercoating
NH Oil Undercoating® is a unique blend of highly refined petroleum, rust inhibitors that guard against rust and corrosion on all metals. It eliminates moisture containing salt, dirt, and other pollutants from the metal providing long-lasting protection for your vehicle.
NH Oil Undercoating protects metals by displacing moisture and treating the surfaces with highly effective corrosion inhibitors. The corrosion inhibitors form an adsorbed . layer on the metal surfaces. This microscopic layer acts like a series of tiny umbrellas, shielding the surfaces from water molecules. Just as a car battery will not work without its electrolyte, metal corrosion will not occur if moisture does not contact the metal
At What Age Do Cars Start To Rust
There is no set age when cars begin to rust. Over the years, wear and tear can damage protective coatings and leave metal exposed to moisture.
Although older models were made before rust-proofing materials were typically used in the manufacturing process, the most-likely reasons for your car turning into a rust bucket depends on other factors.

Types Of Rust And How To Fix Them
Rust forms in stages, and knowing where a problem spot is in that decomposition process can help point you to the right solution. Here are the three main stages of rust and how to fix them.
Surface Rust
The first signs of a problem pop up in paint nicks, cracks, and scratches. An easy fix.
Surface rust is just that: on the surface. Leave a car with steel disc brake rotors parked for a little while, and you can see surface rust form on the rotors. Thats never a threat, however, as that rust is typically wiped off the rotor after just a few stops.
Most surface rust on your car forms when paint breaks down through mechanical or UV damage, which is why even cars in warm, dry climates get it. Structurally, surface rust is not a problem, and depending on the metal’s thickness and alloy composition, a level of “passivation” may even be reached where the surface rust actually guards the metal from further oxidation.
Regardless, it’s best to correct surface rust as soon as you see itjust in case. That patina-coated truck from Arizona may become a hole-filled nightmare in the wrong weather. The fix is much like general paint repair. Start by using an abrasive wheel or sandpaper to cut through the paint and corrosion until clean, bright metal is visible. Rough up the surrounding areas, too, so that your body treatments can adhere well to the car.
Scale Rust
The chemical process corrupts the surface and reduces metal strength.

Five Tips On How To Stop Rust And Maintain Your Car
You see that brown colour appearing at the edges of your car and you know that its time you took better care of it. In simple science: When oxygen, water and salt combine at the surface of a metal, rust forms. Pretty simple, right? Though the formation is quite easy, its the removal that we all hate. How does one exactly go about removing rust when you dont have the dough for getting a regular car wash?
For some people like me, a car represents one of my most valuable belongings, which most people take for granted. Your car is not going to stay in the same condition as the day you drove it from the dealer. Yes, its beauty will deteriorate with time but with a little care and proper maintenance you can keep its overall appearance intact. Now Im not saying that you be that crazy guy on the block who shouts at kids for touching his car and keeps a handkerchief in his pocket to wipe off every speck of dust. Just take a little extra precaution and you will see for yourself that your car will look better.
Below are some tips that will help you stop rust from attacking your car:

Carefully Choose A Parking Spot
Your parking spot is often the culprit for rust. For example, if youre always parking your car in mud, wet gravel, grass or dirt, then your car will be prone to rust. This is because the ground always holds more moisture, and when the moisture evaporates, the undercarriage of your car will come in contact with the moisture, which can increase the chances of rust.
When youre parking your car, youll always want to park on dry surfaces. Some of the ideal surfaces for parking your car drive include pavement, asphalt, crushed rock and cement. By choosing a dry surface to park, youll protect your car from rust that would develop on the undercarriage of your car if you had parked on a wet surface.
How To Deal With Rust
1. Surface rust
- For surface rust, use sandpaper to treat the corroded surface. The sandpaper will remove any remaining paint and remove all surface rust. Sand the area until you see bare metal.
- Once the bare metal is visible, apply a coat of automotive primer and let this dry. Apply paint of your choice. You may choose to apply two coats or more, but you may also use one coat of paint to just top it off with a clear coat.
- Buff the treated area to blend all the paint finishes.
2. Scale rust
- Remove all visible signs of rust using a wire brush. You need this tool because the damage is more serious and has created a noticeable pit.
- Sand the area to get a smooth and clean surface. Just like removing surface rust, dont stop until you see bare metal.
- Apply automotive primer and follow up with paint. You may apply a clear coat of paint if you wish to completely seal the corroded area.
3. Penetrating rust
- Most cars with penetrating rust are done for. The only way to save the vehicle is to replace the affected part. Youre lucky if the part is a small one like your fender or the car door, but if youre dealing with the hood or the entire body, then you may need to pay so much for a panel replacement.
- Some car owners go for a cheaper alternative, and that is to use metal patches to cover the decaying metal. If this is your option, make sure that you deal with the penetrating rust first before you patch it.

Creeps And Self Healing
NH Oil Undercoating® is designed to creep deep into cracks, crevices, spot welds, seams, folds and provide protection there as these areas up prone to hold moisture and are unprotected. So even if the initial application cannot reach one of these areas, this creeping process makes sure the maximum protection is provided!
Do Rust Converters Actually Work
Rust converters are one of the advanced solutions for dealing with extensive rust on vehicles. It turns the corrosive layer into a protective polymeric coating on the car surface. Rust converters are very tricky to use and proper preparation of the vehicle surface is needed to apply it correctly by following the instructions. Rust converters work well for removing medium rust as well as heavy, flaky rust.

Apply The Colored Base Coat
- Holding the spray can about 12 in. away from the surface, spray the repaired area.
- Start at the bottom of the repair and apply the color coat in left-to-right rows, overlapping each pass by about one-third.
- Build the color slowly into the repair and surrounding areas in two to three coats.
- Allow about 10 to 15 minutes between coats.
- Allow the base coat to dry, until it’s dry to the touch, at least 60 minutes.
- Pro tip: Don’t sand the base coat unless you’ve created sags. In that case, sand lightly and then respray the touched-up areas.
Stage 3 Penetrating Rust
This phase represents the most advanced car rusting level. The pin holes from the second stage have penetrated through the panels and metal frames. Because penetrating rust eats through the metallic components, repairing the damage often requires replacing the entire portion or body panel. The best way to avoid the costly repairs caused by penetrating rust is to prevent, catch, and repair surface rust early enough.

How To Fix Small Rust Spots On A Car Or Truck
The process to repair small rust spots depends on how far the rust has penetrated into the metal. Surface rust is a straightforward process that is similar to fixing a scratch or paint defect. Scale rust, which goes deeper, requires more effort to get rid of on your vehicle. If you have the right products, though, the process is fairly straightforward.
Rust On Your Cars Body Is The Primary Concern
Most people worry about the rust they can see, but rust on your undercarriage is far more concerning. Road salt and other contaminants can get trapped under your vehicle, causing serious damage. This is one reason why cars in northern states that are driven in the winter are more prone to rot.
In addition to checking the car’s surface, its important to inspect the underside of your car for rust every year. This is the best way to discover small issues and fix them before they become a major problem.

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 dont 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, its 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, dont 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 wont only prevent the interior parts from rust, but itll also make it look shiny and new.
What Damages Are Caused By Rust
While rusting may seem like little more than a surface issue that affects your vehicles appearance, it can actually be a serious problem that you should not ignore. Vehicle panels can rust from the outside in, or from the inside out, and once the metal is perforated, the only proper repair is a complete panel replacement or section replacement with new metal. If left unremedied, rust damage may eventually make its way to the frame of your car, creating serious structural damage that you may not be able to repair. If you want to keep using your car for as long as possible, then rust is something you cant ignore.
