6 steps to repair rust holes in a van

There are four ways to repair rust holes in a van:

  1. Welding

  2. Fibreglass

  3. Body filler kit

  4. Metal Epoxy putty

In this article, we will look at how to repair rust holes using metal epoxy putty - it's really easy and really cheap. Let's dive in!

Step #1: Sand down the rust

To remove the rust, you will need a drill and wire brush head. You could do the job with sandpaper alone, however, it could take a very, very long time and leave you with a very sore back. Sand back (using the drill) a centimeter or so on each side of the rust spot to ensure you erase any trace of rust.

Step #2: Apply Rust remover

To remove any remaining rust, apply the Rustins Rust Remover. It is excellent for removing surface rust from steel and iron.

The duration of time it takes to remove the rust using rust remover depends on the severity of the rust on your van. Light rust takes around 30 minutes to remove, while heavy rust can take you up to 24 hours.

Apply the Rustins rust remover to a microfiber cloth and wipe the metal with it. It will remove any trace of surface rust from the area. It will also stop the rust from spreading and doing any further damage.

NOTE: Always wear gloves, mask, and protective glasses while applying it. It's a flammable vapour that can damage your eyes and burn your skin.

Step #3: Repair the holes

Once you remove the rust, you may have a hole in the place where the rust was. So, you will have to fill up these holes using metal epoxy putty.

When mixed, the epoxy forms an industrial-strength polymer compound that you can mould into any shape and use to repair or patch up any steel or iron components. It quickly repairs or rebuilds or patches up things made of metal.

To apply it, mould it in your hands till it’s warmed up, then apply it on the inside and underside of the campervan. Leave it to dry.

NOTE: Wear gloves and a mask. Make sure that this protective wear covers your skin to safeguard you from epoxy. It’s toxic and many people find they get faint-headed if they don't wear a mask.

Step #4: Sand the metal epoxy putty

After 24 hours, the epoxy will harden or become rigid. When this happens, smoothen the metal surface by sandpapering the excess putty.

Step #5 (Optional): Use a primer

Now that the rust is out, you need to repaint your campervan. Before painting it, add a primer layer to the metal (iron or steel). It will protect it against rust.

Step #6: Apply metal paint

For excellent results, use Hammerite white metal paint. It provides a very smooth finish and protects metal from any weather elements. When painting, paint both the top and the underside of the epoxy.

Step #7 (Optional): Apply Underbody Seal to the bottom of the van

If the bottom of your van is in poor condition, you might want to do a proper job with an underbody seal. It gives heavy-duty protection for the underside of your campervan and other high-impact areas that are exposed to various things like stones, water, and corrosion.


For effective rust removal, you will need to strip your campervan bear first.

  • Remove all the inside panels and the flooring that comes with the van.

  • Remove the plastic exterior trim panel rims. When it comes to a campervan, you will never look at a painted car the same. It has so much rust under the paint. And it is essential to remove it before it spreads and does more damage.

  • Leave the campervan bear. This will give you room and help you assess your van correctly. Upon inspection, you will see the affected areas, and once you have marked them, you can start on the rust.

Also, carry out regular checks to maintain a rust-free campervan.
