How To Fix Major Rust On A Car: A Guide

It’s easier to prevent rust than to remove it so at the first signs of rust its best to do something about it but remember that if you have failed to catch it early there are some things that you may still be able to do. But take note that some rusted regions may be more difficult to repair than others, and this is mostly dependent on the degree of rust. Because rust is caused by the oxidation of the metal itself, heavily corroded metal can’t always be cleaned and may need to be replaced.

Fortunately, if the rust on your car is the consequence of an accident or a poor repair job, then comprehensive car insurance policies may cover its repairs since it isnt caused by natural wear and tear. Contact your insurance carrier immediately once you discover the rust. Rust caused by improper care or normal wear-and-tear however is not covered so you will have to pay out of pocket for the service repair or do the fix yourself.

The fix may be mild and severe where you will have to learn how to fix major rust on a car. When it comes to severe rust, the rust has usually eaten all the way through the vehicle’s sheet metal. You might be able to patch the hole in the sheet metal using body filler if it’s little, but if it’s huge, it’s probably best to replace the complete rusty panel. Before you begin, think about your budget and the extent of the damage.

Spray On The Clear Coat

  • Apply several coats of clear coat, allowing the recommended drying time between coats.
  • Gradually work the clear coat into the surrounding painted areas to achieve a smooth blend line.
  • Note: This is the hardest part because all clear coats run easily and that will ruin the look of your paint job. If you create a run in the clear coat, you’ll have to let it dry for at least 48 hours before attempting to fix it with fine-grit sandpaper and polishing compound. Then you’ll have to respray the sanded area. So practice spraying on a scrap piece of cardboard to get a feel for the nozzle and the speed of application.
  • Let the clear coat dry for several hours before driving the vehicle and at least 48 hours before buffing.

    You can apply touch-up paint to stone chips, small scratches, and other minor nicks and dings, but truly repairing rust can take several steps, a variety of tools and materials, and quite a bit of skill.

    If youre skilled enough and daring enough you might be able to tackle surface rust and small rust spots. First, use fine-grit sandpaper or a razor blade to remove the rust. Then treat it with a spray-on rust inhibitor and apply primer. Finally, cover it with touch-up paint that matches the color of your vehicle. Touch-up paint is available from dealers, auto parts stores, and automotive paint suppliers.

    Depending on the size and severity of the rust, blending the repaired area with the surrounding paint may require wet sanding or buffing the surface. Wet sanding involves mixing an automotive soap with water, soaking fine-grit sandpaper in the solution for several minutes, and then gently sanding the repaired area to blend it in. This is a process that requires skill and can do more harm than good if done incorrectly.

    If there are larger areas that have been eaten away by rust, repair is probably best left to professionals.

    Modern vehicle finishes are extremely durable, but over time its inevitable that stones and grit thrown up from the road will scratch the underside of the vehicle and the paintwork. Accidental knocks and dents will also break the protective skin. Bug bodies and bird poop contain acid that starts to eat away at paint surfaces in as little as 48 hours.

    Anywhere theres damage, oxygen starts to attack the steel underneath and forms rust. Left untreated it can spread quickly and soon becomes a real problem. So, what can you do about it?

    How To Stop Rust From Forming

    The good news is that this kind of vehicular decay is largely preventable. The best advice is the most obvious: Wash your car regularly to keep the body and underside clean of the road grime, salts, and dirt that lead to corrosion. Many modern car washes can blast the underside of your car with water to get much of this grime off.

    The not-so-obvious advice is to check the drain holes along the bottoms of doors and rocker panels, which allow rainwater to flow out. Use a pipe cleaner to clear these holes out, and keep the cars nooks and crannies dry. WD-40 can be a useful tool here as well. This lubricant protects parts from corrosion, and its thin nozzle can be used to reach tight underbody spots and blast away water or corrosive grime.

    As noted earlier, many vehicles have a thick coating on the underside that chemically seals the steel against oxidizing agents. Regular inspection and repair of the spots that have worn bare will keep rust from advancing and causing additional damage. If this coating is not there, consider adding one yourself. POR-15 is one of the more popular examples of such a rust-protective sealant, and they even have a rubberized coating to go over it in case you want even more protection underneath your car. As with other rust repairs, sand off any rust that might be sticking through and rough up the area you intend to paint with some sandpaper, then brush or spray the new coating on.

    How To Prevent Rust On Your Car

    Rust may be one of the biggest nightmares you may have to face as a car owner. If not fixed early enough, what starts as harmless brown spots on the surface could eventually cost you thousands of dollars in repairs. At worst, they could easily take your vehicle to its early graveyard. Car rust is preventable, though, and doesnt require any specialized skills.

    The easiest way to keep your car from rusting is by giving it a good wash at least once every 1-2 weeks. Washing your car regularly removes built-up grime, salt, dirt, and other common car corrosion causes. If you cant manage to wash your car manually regularly, an automated car wash is an excellent alternative.

    Secondly, keep a close eye on the drain holes. More exposed areas, such as the doors and windshield, have holes that allow water to exit. If not checked regularly, these holes may get plugged up with dirt, leaves, and dead insect remains, causing water to accumulate. To prevent rust around these areas, always know where your cars drain holes are located and ensure that they are always open.

    Go Shopping For Supplies

    • First, find the car manufacturer’s paint code.
    • Note: The paint code can be in a variety of places on the body, in the engine compartment or trunk, or other places. Use either of these online resources to find instructions on how to locate your paint code: or
  • Buy automotive touch-up paint in pints and quarts to use in a spray gun, in aerosol cans, or in roller ball applicators.
  • Pro tip: Even if you know how to use a spray gun, mixing automotive paint with a reducer to match the temperature and humidity conditions can be mighty tricky. We don’t recommend it. Instead, buy aerosol cans for larger repairs and rollerball applicators to fix scratches.
  • Note: Most late-model vehicles were painted with base coat/clear coat paint. The base coat contains just the pigment and binding resins-the clear coat is just the gloss.
  • Buy equal amounts of both base coat and clear coat.
  • You’ll also need an epoxy self-etching primer to bite into the bare metal and a lacquer primer to hold the paint.
  • Buy 40-, 600- and 1,000-grit sandpaper, a sanding block, grease and wax remover, poly sheeting, painter’s tape, a tack rag and a microfiber cloth.
  • Why Do Cars Rust

    Chris is Wrong, You Can

    Its common for older vehicles to get rust spots, especially when theyre exposed to saltwater or road deicers in cold-weather climates. Over time, chemicals, dirt and road salt can all cause the top layers of your paint to weaken. Unrepaired scratches and dents from minor fender benders and stray grocery carts can also promote rust formation, even on newer cars.

    When bare metal gets exposed to water, iron and air it starts corroding due to a chemical reaction known as oxidation. Once saltwater starts accelerating the oxidation process, you might notice a small rust spot around your wheel well or near the bottom of a door. Once that rust spreads, it not only looks bad and lowers your resale value, it can start corroding structural components and body panels.

    Wash And Wax Your Car

    The easiest way to prevent rust is the most obvious: Wash and wax your car often.

    Dirt can retain and trap moisture, and road salt, bird droppings, and other corrosive materials will eat away at paint if theyre left unattended on metal surfaces for long periods.

    Washing your vehicle frequently will remove these corrosive materials. Waxing it on a regular basis will add a protective surface to the paint and clear coat. Wash and wax more frequently if you live near an ocean or in an area where highway crews spread salt on the roads to melt snow and ice during the winter. Salt is Public Enemy No. 1 when it comes to rust prevention.

    Is Repairing Rust A Must

    Dealing honestly with customers and knowing your costs for performing rust repairs are essential. These two things may well be the key to successfully performing rust repairs. Unfortunately, honesty sometimes gets lost in the business of making a profit.

    Short-term rust repairs and long-term rust repairs are like day and night. And even best efforts sometimes fail to make a long-term rust repair last longer than six months. For reasons such as this, customers need be informed of the cost of different rust-repair methods vs. their longevity.

    And dont ever forget that rust repairs must ensure the vehicles structural integrity this is an absolute must for unibody vehicles. Know when to say, No, this vehicle cannot be made safe for the road.

    As with any profit center, rust repairs can provide additional profits to your shop, but they also bring with them additional responsibilities. Is taking on rust repair a smart move for you? Will it be profitable? Is it worth it? It has been for some. But only you can determine if the rust repair aspect of the business is right for your business.

    What To Do If Rust Gets Serious

    Rust that penetrates deeply into the metal or that creates holes requires a replacement panel. For severe rust problems that cannot be repaired by the two processes outlined above, you will need to cut out and replace the body panel, or a portion of it. While you may be able to patch a portion of the affected area with a piece of sheet metal, its often easier to just replace the entire panel.

    To install a patch, you must cut out the portion of the original panel that has the severe rust and holes and then weld the patch in its place. The finished appearance will depend on how good you are at welding and the quality/thickness of the sheet metal patch. For larger areas, or areas that overlap body lines, install a replacement body panel.

    Choosing a new panel for your vehicle is simple. Enter your vehicles year, make and model into the search bar on this site to see whats available. We have replacement panels for models dating as far back as 1947. Our replacement body panels are designed to precisely conform to the exact specifications of the original. Our panels are made from heavy-gauge stamped steel and utilize 3D scans of an OEM part to ensure perfect fitment. The engineering precision ensures the panels fit without modifications.

    Here are just some of the many panels we have for repair or restoration:

    How Does Rust Occur

    How to Repair Rust on Your Car Without Welding (No Special Tools Needed)

    Rust is impossible to avoid since its a natural chemical process that occurs when iron, a core component of steel, comes into contact with moisture and oxygen. The earths atmosphere has plenty of water and oxygen to spare, making it a common element of our ecosystem. Any steel exposed to the air will eventually corrode due to a process called oxidation.

    However, some types of steel take longer to corrode than others. Furthermore, modern cars are manufactured with a far more durable galvanized steel, a corrosion-resistant material.

    Your cars paint also plays a pivotal role in preventing rust damage. It physically prevents oxygen and water from coming in contact with the steel beneath its surface.

    Generally speaking, as long as you regularly wax your car and take care of it, you probably wont have to worry much about rust. But if you have an old car you want to fix up, or your vehicle has accumulated rust from being left outside for months, there are ways you can repair the corrosion without replacing the steel wholesale.

    How To Fix Rust Spots On A Car

    I drive a 1985 VW Golf , and it’s in pretty good condition for being 21 years old. There are three spots on the front left fender that have rust on them. Someone had hit the car and the paint came off, so it became rusty. These spots are not only an eye sore, but they are sure to spread in the salty Nebraska winters.My goal in fixing these was function, and not so much glamour. The car is kind of a beater, so I wasn’t too concerned with making it look perfect. As long as the rust was gone, it would look better, and I wouldn’t lose a fender.

    What Is Rust When It Appears On Your Car

    Car bodies are made out of steel, an iron alloy created by strengthening the composition of iron by adding carbon. That steel is often sealed by several layers of primer, paint, and clear coat to protect it from the weather.

    Rust is what forms when a metal or alloy, that contains iron, oxidises. That oxidation causes the metal to break down, resulting it the substance that we know as iron oxide or rust.

    Rust can affect cars due to a number of different reasons however, most commonly it can be because a scratch or dent cuts through the different protective layers and leaves the steel vulnerable to the elements. Water and additional moisture in the atmosphere can then interact with the steel, causing it to break down.
