How to PROPERLY Repair a Rust Hole in your Car or Truck (DIY for Beginners)

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.

What Causes Rust On A Car

Rust develops when iron reacts with oxygen and water. The oxidising appears as a reddish-brown coat that can lead to corrosion.

This damage usually happens in cars because of a combination of factors:

  • Climate Regular exposure to rain, sleet and snow will increase the chances of moisture oxidising with metals on your car. Salts used to grit icy roads can also speed up the corrosion process, while higher temperatures generally lead to higher rates of corrosion too.
  • Age Over time paintwork and protective coatings can suffer from wear and tear. If metalwork is exposed to moisture it will eventually rust and corrode.
  • Materials Older cars were generally made without non-reactive coatings, leaving them more vulnerable to rusting. Newer cars also use arch liners to prevent damage to the wheel wells.
  • Driving style If you tend to drive off-road or through puddles you could be increasing your corrosion risk.

Beware Of Obstacles And Bumps:

Weve all been guilty of slamming into a bump in the road or hole a little too hard. Failure to slow or stop when reaching a shift in road level, on the other hand, not only leads a motorist to worry but also has a significant influence on the underneath of your car.

Striking a hole or a bump at ridiculous speeds can cause damage to the structure beneath your automobiles, such as the muffler and chassis. With it in mind, if you see a bump in the road or hole coming, you must drop your speed gradually.

If you hear sirens when driving over a hole or bump, its a sign that you havent slowed considerably and should take extra caution in the future.

How To Protect Your Car From Rust

Now that youve fixed the rust on your car, its a good idea to learn how to protect your vehicle from further rusting. While a car will naturally rust over time, you can take the following preventive measures to stall the spread of rust.

  • Watch where you park. Although a lousy parking spot can be unavoidable, parking your car on snow, grass, dirt, or poorly drained areas invites moisture and the rusting process.
  • Keep it clean. Checking horizontal surfaces and the underside of your car or truck and keeping the bottom of your vehicle clean are two of the best ways to prevent excessive rust from forming.
  • Blow it clean. The cost of taking your vehicle to a body shop and lowering your fuel tank out for inspection is high and unneeded. Spray compressed air on your fuel tank and fuel pump to blow any dirt and dust away to thwart the development of rust.
  • Use rust inhibitors. While rust-proofing companies cannot legally promise their products can protect against rust, it wont hurt to use them. You can buy rust inhibitors at most auto parts stores to protect against potential rusting.

This area of the country spans much of the Northeast and Midwest, where year-round exposure to dampness in the form of rain and snow can contribute to rust.

    How To Prevent Rust

    Thankfully, there are a few things you can do stop rust and corrosion from forming.

    Rinse and dry

    If you live by the sea or have been driving in adverse weather you should try to give your car a quick rinse with water. A once-over with a hose will prevent the dirt and grime of the day settling on your paintwork and eventually rusting.

    Just remember to finish the job with a quick chamois rub over.

    Add a coat of wax

    A coat of wax will add a protective layer to your paintwork. You can even try using a wax injection gun to reach those areas where moisture is likely to collect over time.

    Apply oil

    WD40 is a great tool in the fight against rust and corrosion, in fact, the WD stands for water dispersant. Applying the solution with a smart straw will help you drive out moisture from hinges, joints and other hard-to-reach areas.

    Keep your car dry

    Parking your car in a garage will help protect it from the elements but you might want to go further to ensure its safe from rust. After youve parked your car in a garage you can try using a dehumidifier to remove any moisture in the air.

    The RAC Shop is filled with items to help maintain the exterior of your car.

    Rocker Panels And Wheel Flares

    Your rocker panels are the lowest point of the body under the doors, and the wheel flares are the lowest point on your fenders and quarter panels. Being the lowest point on the body makes them one of the first contact points for salt and water. Plus, they curve under the vehicle, leaving a flat spot for salt and water to accumulate.

    This is the perfect storm for rust, which is why itâs so common to see cars driving around with the area under their doors and the base of the fenders and quarter panels completely rusted out.

    • In two to three applications, gradually work the color into the repair and nearby region.
    • Between coatings, wait 10 to 15 minutes.
    • Leave the base coat to cure for at least 60 minutes, or until it is dry to the touch.

    Tools You Will Need For Surface Rust Repair

    Getting rid of surface rust can take as little as 20 minutes of hands-on time for a small job. Larger areas of rust, or scale rust, require more time to repair than small areas. Penetrating rust takes more time to correct than surface rust. Dont forget to factor in the time it takes for the paint and finishing coats to dry. If you use Zero Rust, which is both a primer and a base paint, you dont need a separate primer. To save yourself time during the process, gather the tools and materials you need before you begin:

    • Plastic sheeting

    If the rust gets deeper than minor pits, you may need to spot sandblast or replace the body panel. If the rust is extensive, body panel replacements are typically easier to install than patches, and the final product often looks better.

    When working with auto paint and sanding, protect your eyes, skin and lungs. At a minimum, protective goggles, gloves and a painting mask should be used.
