Whenever you rotate your tires — about every 8,, kilometres — check your wheel wells and bumpers, prime areas for the onset of rust. Rinse dirt off with a garden hose and inspect the area with a flashlight. Do you see a rust spot or two? Have it taken care of ASAP.
And, by the way, did you know that mud flaps do a great job of protecting against water, snow, salt, and gravel all rust hazards? Beware of scratches in paint. Otherwise, a body repair expert will be needed to sand away the damaged paint and any incipient rust, and then treat in a 4-step procedure: 1 primer, 2 paint , 3 clear coat, and 4 buffing.
Be gentle with your car. Treat your ride right to prevent those nicks and scratches that eventually le ad to rust. Remove snow the right way — use a foam brush without stiff bristles. Avoid placing your bag or briefcase on the car even for a minute and be careful never to let your keys scrape the side. Are you wondering whether your car is worth repairing due to rust? You may be pleasantly surprised. Here are the three main stages of rust and how to fix them.
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. 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 it—just 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 we used grit 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. Next, use a rust inhibitor or converter to impede the tin worm's progress. Rust inhibitors convert iron oxide into a chemically stable, moisture-resistant compound that protects the rest of the metal underneath.
For example, the Permatex Rust Treatment we tried contains tannic acid, which reacts with the rust and converts it to iron tannate which is stable and 2-Butoxyethanol, an organic polymer that acts as a primer atop the metal. Then put on some rubber gloves and apply the rust converter with a brush or sponge. You'll want to pour as much rust converter as you think you'll use into a disposable container because you can't double-dip into the bottle.
Wipe a thin layer of rust converter onto the metal and wait 15 to 30 minutes for it to dry. Then add a second layer and wait at least a half hour for it to dry. If you can keep the surface moisture-free for 24 hours, then you could prime it—this Permatex Rust Treatment isn't a primer for paint.
Follow up that primer with paint and clearcoat, then buff to blend the finishes. This is because iron oxide molecules are physically bigger than those of iron or steel. That worsening rust issue self-propagates by expanding and flaking away the outer layers of paint and metal, exposing fresh base metal, which then corrodes. When rust penetrates into the surface like this, it causes a rough, pitted type of damage called scale.
But this is a common myth in the streets, the reality is that although the car has signs of oxidation, it can be fixed. We must also remember that there are different types of rust proofing, so depending on how severe our case is a specialist can tell us what the best option is.
According to Mighty Auto, "a new rust spot can be grinded down and retouched so that it is not an issue. Now granted, if a rust spot is allowed to build and grow, there may not be much that can be done. Still, if caught early, a car can be salvaged and rust can be repaired.
Small details matter and the first sign that surface rust can occur is when the paint is broken down by mechanical damage or otherwise. This is the most common oxidation problem in cars and the easiest to solve. Popular Mechanics suggest, "it's best to correct surface rust as soon as you see it. The fix is not unlike general paint repair. Start by using an abrasive wheel or sandpaper to cut through the paint and corrosion until clean, bright metal is visible.
Next, apply primer, followed by paint, then clear coat. Buff to blend the finishes. If your vehicle has already developed rust in various parts of the body, do not panic, you still have several solutions available to solve the problem.
What many people do not know is that although a process of oxidation has already begun in the car, the process can still be slowed down by using rust proofing. Also, when we apply this type of techniques in our car, even when there are already rust features in the body, we help to protect the parts that are in better condition. Moreover, it is always advisable to ask a specialist what is best for our specific case. In that way, we can prevent the rust from spreading further.
Sometimes the solutions to future problems lie in the basics. What many people do not know is that applying wax to our vehicles with some frequency and washing them helps not only to make the car look clean and highlight the color, but also we are helping to extend the life of the paint.
And when it comes to rust, if we make sure to properly apply wax on our vehicle before the first snowfall, we are helping to create an extra layer of protection before the change of season, so we slow down the rust creation process. Each change of season can become the worst enemy of our car, and of course, drastic weather changes do not help with rust.
And although winter can become one of the most complicated seasons for rust proofing our vehicle, there is no evidence that will affect the results regarding the quality of the process. Mighty Auto explains that "the real culprit when trying to rust proof is salt, dirt, and buildup. As long as your vehicle is thoroughly cleaned off, then you should be okay. Also, even if the process is affected by the weather, some added protection is always better than none.
Unlike what many people think, oxidation can occur on any part of our vehicle, and often in less visible areas. A common myth is that oxidation always occurs on the surface of the body where we can notice it instantly. Thus, whenever rust appears on a vehicle, some immediate concern is warranted.
Rust leads to vehicles losing their integrity and causes them to be unsafe to drive eventually. Additionally, rust creates an uneven, jagged surface on cars that children and adults may accidentally cut themselves on.
Rust does not cause tetanus; it is a bacteria that often lives on rusty objects that causes tetanus. When it comes to rust, deciding when it needs addressing from a professional can be difficult.
In some respects, rust seems harmless, nothing more than an eyesore on the family hatchback. But, you can generally find out if rust needs immediate attention by inspecting the areas of a car most prone to rusting and diagnosing the stage of the rust.
The combination of rust stage and location will determine the severity of the situation. Rust damage occurs in three stages—the later the stage of rust, the more expensive and dangerous the situation. Seemingly minor damages like a fender bender or hail can cause extensive surface rust development. In terms of urgency, the risks of surface rust to a vehicle or its occupants are relatively low. Surface rust is more a cosmetic detriment than anything.
However, it should not be left alone for long. Ignoring surface rust allows it to develop into a deeper, more expensive, and far more dangerous vehicle and family situation. Yes, surface rust is fixable.
Most DIYers can manage the repairs themselves. With some sanding and elbow grease, surface rust easily removes from a car. Provided the damaged area is painted and sealed correctly, the rust should stop developing. Scale rust bridges the gap between extreme rust damage and easily repaired cosmetic rust.
When surface rust is left untreated, it continues to grow until it pits the metal, becoming scale rust. Scale rust is a more severe situation than surface rust. The vehicle is weakened against impact and becomes less durable, making it less safe to drive and prone to more damage in an accident. Yes, when caught in time, scale rust is fixable with a similar process to surface rust.
