A car is a significant investment for most people. So, it’s vital to maintain its condition, inside and out. Vehicles and other steel materials are prone to corrosion when not properly maintained. Cars left uncovered under the sun are also at risk of severe rusting since UV rays can speed up the process.
You may encounter three common types of rust on cars. These are:
- Surface Rust: This type only affects the topmost layer. It may happen after receiving a deep scratch that penetrates the paint.
- Scale Rust: If left untreated, surface rust can evolve into this. It will affect your car’s body and ruin its structure.
- Penetrating Rust: You don’t want to see this in your car. It shows up as holes in the surface and is hard to fix unless the affected areas are replaceable.
Repairing minor corrosion as soon as you see it will prevent it from spreading and further damaging your car. Fortunately, you can remove rust if you know how to do it correctly. Here’s how to fix this common vehicle problem:
- Prepare Your Tools
You need the right tools to remove rust effectively. You cannot expect a good result without the right tools. To help you, these are the primary instruments you’ll require in your rust-repair kit:
- Sandpaper, sanding block tool, or mechanical sander
- Masking paper
- Tape
- Angle grinder
- Touch-up paint
- Body filler paint
You’re free to ask for professional help if you’re unsure how to repair car rust without making mistakes. They can give you a hand while you work along with them or do the job themselves. Car repair service teams may fix up one rusty vehicle or multiple, depending on how many of your cars are affected by corrosion.

- Move Your Car To A Suitable Location
When fixing your car due to corrosion, you must work in a smooth and stable area to have enough space to move. You can repair your rusty vehicle outdoors if the weather permits or in a clean garage. If miscellaneous items are nearby or in the way, put them aside safely before working so these objects won’t get dirty in the process.
Once you’ve settled on a spot, it’s time to cover the non-rusted parts of your car. The masking paper and tape will protect the unaffected areas and help you focus on the places that need your attention. You can also use taped-down newspapers or poly sheeting if you have it.
- Start Sanding
You don’t need to cut off rusted parts unless the vehicle is corroded or you’re doing a classic car restoration. It’s best to use sandpaper with a 40-grit or more for maximum efficiency in sanding out the corrosion. Note that when you sand your vehicle’s surface, you remove the rust and the paint with it. Make sure you remove every tiny bit of rust before the next steps, or that spot will spread again if left untouched.
Use sandpaper until you see the clean and bare steel underneath the affected area. You can speed up the process with a mechanical sander or angle grinder, or consider a sandblasting service auckland for more efficient surface preparation. But if you choose to use the latter, ensure that you use fire-resistant material covering to protect your vehicle from sparks.
- Apply Fiberglass And Body Filler
To ensure the newly sanded area is fully fixed, apply fiberglass repair gel mixed with hardener behind where the rust used to be. Once the mixture hardens, you can sand away the excess fiberglass.
After applying the gel and sanding it, you can fill the holes with body filler. To minimize sanding and extra applications, apply the mixture evenly into every nook and cranny that needs attention. Clean with a rag and mineral spirits, then let it dry. Avoid leaving lint, dust, fingerprints, and oil on the area to prevent the paint from running and getting spotted later.
- Prime And Paint The Surface
Your car should now be ready for repainting. But before that, you must prime the surface. By exploring shot blast media you can ensure the rust has been removed from your car and the surface is cleaned prior to applying any primer. Shot blasting also strips any old paint to ensure your surface is consistent.
Once your surface is ready, spray primer on the bare steel and sand it after applying the first layer. This step ensures you remove any leftover rust particles. Repeat this prime-and-sand process until satisfied.
When painting, apply a thin layer first. As in the priming step, sand it down after each layer dries. Use a piece of 400-grit sandpaper or a sanding block on the dry paint to smooth the surface. You should have a total of three paint layers.
- Spray-On Clear Coating
Once everything is done and dry, spray several layers of clear coat on the area. Let each layer dry before you spray another. After that, hand-buff the spot with a microfiber cloth with a polishing compound.
The clear coat will protect your new car paint from fading and scratches. The latter is a typical auto repair issue everyone should know how to fix.
- Prevent Rust From Coming Back
It’s not over just because you’ve repaired your rusty car. You still need to take preventive measures to avoid corrosion from happening again.
Regularly inspect for rust in the following areas:
- Wheel wells
- Doors
- Windscreen
- Exhausts
- Suspension
- Frame rails
- The floor of the boot
When you find rust, attend to it immediately before it spreads. You can apply wax on the paint and oil to rust-prone areas. If you live in places with constant moisture, keep your car dry and covered.
Conclusion
Removing rust is tedious, but with enough work, you can restore your car’s original appearance. With the right tools, skills, and patience, your vehicle can look like new again.
