DIY Rust Repair: How to get rid of rust on your car

The best time to treat your vehicle is when you have small surface rust spots. But it’s never too late to remove rust. Even in some of the most advanced stages of rust development, you can still save your vehicle.

Here’s what you need to know about getting rid of rust on your car or truck and preventing it from returning.

Different Types of Vehicle Rust

Rust can damage your vehicle in a variety of ways, and the problem will quickly progress if you wait too long to correct it.

Over time, minor surface rust can penetrate deeper into the metal. Even worse, what looks to be minor surface rust may just be the tip of the iceberg, as it’s very common for rust to start from the inside of a panel and work its way outward. Ignore rust spots long enough, and you could find yourself with a vehicle filled with flaky rust holes.

There are three types of rust. Here is a look at each:


Surface Rust

Surface rust only affects the top layer of your vehicle’s body panels. This rust appears in nicks and chips in the protective paint coating. Treat rust at this stage for the most straightforward process. You will also get the best results with the least amount of effort if you treat surface rust immediately and do not allow it to spread further.

Pro Tip: The best way to avoid surface rust is to keep a small bottle of automotive paint (color to match your vehicle) in your garage and touch-up minor nicks and scratches as they happen.

2. Scale Rust

Scale rust occurs when you leave surface rust to continue the corrosion process until it pits the metal.

Chemical reactions cause rust that begins to damage the metal of the body panel itself.

How to Remove Surface Rust From a Vehicle

Road salts and salt spray are notorious causes of premature rust in cars and trucks, especially in Northern states. These salts create a chemical reaction that speeds up the corrosion process.

Eventually, scale rust will work its way through the surface of a body panel and affect the integrity of the metal itself.


Penetrating Rust

Penetrating rust is, as the name suggests, rust that creates holes in the metal. This type of rust is the most advanced stage. You will need to replace portions of, or entire, body panels of your truck to repair the damage.

The best method to avoid penetrating rust is to prevent or repair surface rust in the first place.

Pro Tip: Fluid Film applied to the undercarriage of your vehicle is an excellent way to protect the chassis and inner body panels from damage caused by road debris and road salts. This protectant is so effective that the marine industry has used it for over 50 years.

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. Don’t forget to factor in the time it takes for the paint and finishing coats to dry.

How to Repair a Rust Hole in Your Car

If you use Zero Rust, which is both a primer and a base paint, you don’t need a separate primer. To save yourself time during the process, gather the tools and materials you need before you begin:

  • Plastic sheeting
  • Painter’s tape
  • Sandpaper (180-grit, 320-grit, and 600-grit, or finer)
  • Wire brush
  • Wax and grease remover
  • Lint-free cloth or microfiber cloth
  • Body filler and applicator
  • Automotive paint to match your vehicle

Optional items (depending on the amount and location of the rust)

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.

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.

An Overview of Fixing Surface Rust Spots

To ensure your truck or car doesn’t deteriorate, it’s important to fix surface rust spots as soon as possible.

Start by preparing and cleaning the area. Then, sand rust out with sandpaper or a grinding disk until you see clean metal. After you’ve removed the rust, protect the surface from future corrosion by using Zero Rust paint as a base layer.

This product is designed to seal the affected area from oxygen, providing superior rust protection for whatever topcoat paint you apply. Once dried, you can apply an automotive paint to blend the repaired spot into the rest of your paint color.

Repair Small Surface Rust Areas

Surface rust areas require sanding out the rust stain and recoating the surface with paint.

Different Types of Vehicle Rust

Here’s how to get the job done:

  1. Prepare the Area: Prep your workspace. Tape plastic sheeting over your vehicle, leaving a gap the size of the treatment area with a few inches on all sides.
  2. Don Safety Gear: Put on your protective eyewear, gloves and dust mask.
  3. Clean the Surface: Use wax and grease remover to clean the area that you are about to sand.

    If you don’t clean the area prior to sanding, then the sanding process can contaminate the metal.

  4. Sand Away the Rust: Use sandpaper or a small grinding disc to sand out the rust spot, including the paint directly around the rust area. Keep going until all the rust has been completely sanded out and you see the shiny metal base.
  5. Clean the Surface Again: Clean the area with wax and grease remover to ready it for primer and paint.
  6. Wipe off Dust: Use a lint-free cloth or tack cloth to wipe away any dust from the surface.
  7. Apply Zero-Rust or Other Automotive Primer and Paint: If you use a rust-prevention paint like Zero Rust, you don’t need a separate primer.

    It should dry to the touch in 30 minutes, depending on temperature and humidity. Apply a second coat if needed after the first dries. Once your primer or Zero Rust dries, scuff it, clean it and then apply your topcoat of automotive paint.

  8. Buff the Finish: Buff the treated area with a microfiber cloth or a lint-free cloth.
  9. Wait for a Wax: Don’t wax your vehicle for at least 30 days.

    Putting off washing and waxing allows the finish to completely cure.

Tools Needed for Scale Rust Repair

Repairing scale rust requires most of the same tools as repairing surface rust.

Here’s what you’ll need:

  • Plastic sheeting
  • Paint tape
  • Grinding discs and sandpaper (180-grit, 320-grit, and 600-grit, or finer)
  • Wire brush
  • Wax and grease remover
  • Grinding tool
  • Lint-free cloth or microfiber cloth
  • Body filler and applicator
  • Automotive paint to match your vehicle

Optional items (depending on the amount and location of the rust)

Remember to protect yourself when working with automotive paint and sanding.

How to Fix Scale Rust

Scale rust pits into the metal, causing more than just surface damage.

You will need to get more aggressive with your techniques to fix scale rust damage. Ignoring the problem will allow it to get worse until it eats through the metal completely. Keep in mind, fixing scale rust will require more effort and time than repairing.

Here’s what you need to do to repair scale rust:

  1. Prepare the Area: Cover the area surrounding the rusty portion with plastic sheeting.

    Best option for repairing tiny rust spots on car

    Tape it in place. Allow at least six inches on all sides of the rusty area for working space.

  2. Put on Safety Gear: Protect yourself by putting on safety goggles, gloves and a dust mask.

    These precautions are even more critical with scale rust removal because you will use a grinding tool to get rid of the problem.

  3. Clean the Surface: Use wax and grease remover to clean the area that you are about to sand. If you don’t clean the area prior to sanding, then the sanding process can contaminate the metal.
  4. Grind the Rust: Use a grinding tool (usually a right angle grinder) with a 2″ or 3″ grinding disc to remove the rust.

    You can start with an aggressive grit, such as 36, to remove heavy scale, and then move to a less aggressive grit, such as 80 or 120, to remove the remaining rust and surrounding paint.

  5. Mix Prep Step: Combine Zero Rust Prep Step with hot water. Use 12 ounces of product per gallon of water.

    Fill a spray bottle with this solution and spray the affected area.

  6. Rinse Prep Powder off: Use a rag and clear water to wipe off the rust conditioning powder solution.
  7. Fill in Depressions: Use body filler to fill in depressions in the pitted metal.
  8. Sand the Surface Smooth: Use sandpaper and a sanding block to smooth out the body filler, metal and surrounding paint edges. Start with 180 grit and work your way to 600 grit.

    How to Fix Rust Spots on a Car

    Each grit will help remove sanding grooves left from a previous step.

  9. Clean the Surface Again:Clear off dust and debris and clean the area with wax and grease remover to ready it for primer and paint.
  10. Wipe off Dust: Use a lint-free cloth or tack cloth to wipe away any dust from the surface.
  11. Apply Primer and Paint: Apply two coats of Zero Rust paint or primer to the prepared, clean surface.

    Wait for each coat to dry before applying another. Once the primer or Zero Rust dries, sand the entire area again with 600 grit sandpaper, clean with wax and grease remover, and then topcoat with your automotive paint.

  12. Buff: Buff the dried coating with a lint-free cloth.
  13. Wait: Don’t wax the freshly restored area for at least a month.

If the scaled area that you’re working on is the undercarriage/frame of your vehicle, there is no need to topcoat over the Zero Rust paint.

For added chassis protection, use Fluid Film. Fluid Film creates a barrier against the rust-causing agents your ride may encounter on the road.

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, it’s 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.

    Whether rust or damage gets to them first, at some point you will need to replace some portion of them. We stock lower quarter panels and bed panels for both trucks and SUVs.

  • Wheel Arches: Wheel arches catch debris your tires kick up from the road, including corrosive road salt and water.

    These parts are prone to rust, but with our selection of wheel arches for vehicles from Chevy to Ford to Dodge, you can replace them easily.

  • Doors: Rusted through doors create a safety and security hazard. Don’t settle for subpar parts. Find replacement lower door panels and all the interior hardware you need, like window regulators, handles, strikers and more.
  • Rocker Panels: Rocker panels on almost every vehicle hold road salt, mud and road debris and eventually rot out.

    We carry a huge selection of slip-on and weld-on rocker panels for many makes and models of cars, trucks, vans and SUVs.

When your vehicle has reached the stage of rust damage that requires replacing a panel, turn to us at Raybuck. You will find high-quality panels made to OEM specifications at lower prices. Don’t forget the rust-inhibiting paint and rustproofing materials that we carry as well.

With paint like Zero Rust you can protect your newly replaced panel, even in harsh conditions. Zero Rust performs exceptionally well in tests, exceeding the 2,000-hour salt spray test.

If the rust reaches the stage where the frame of your vehicle is penetrated, get a professional inspection.

Rust can compromise the strength of your vehicle’s support system.

Method 1 of 2: Using a body filler kit to repair the hole

A rusted frame could cause severe problems in the future, and most home mechanics will have trouble properly evaluating and properly repairing the damage.

If your vehicle’s frame is in good condition, you can help keep it that way by using Fluid Film to protect the undercarriage of your vehicle.

Rust Repair and Prevention With Raybuck

As much as auto manufacturers prepare their vehicles to prevent and reduce rusting, their efforts always seem to fall short.

And in harsh climates, vehicles are even more susceptible to damaging rust. Take action now to prevent rust from forming on your vehicle. Start by applying rust inhibiting products such as undercoating or Fluid Film. If you already have rust damage, then look at applying a rust inhibiting paint, such as Zero Rust prior to an undercoating.

Use these before rust takes hold on your car or truck or after treating a corrosion problem to prevent future issues.

When rust eats through the body on your vehicle completely, step up your game.
