For any car owner, one of the last things you want to deal with is rust. It can really do a lot of damage to your car and it can also be costly to fix. Once rust sets in, it gets hard to prevent it expanding, especially in areas not visible from outside of the car. Because of this, you want to make sure you do everything you can to try and keep your car free of rust. The following are some of the best ways to prevent rust on your car.

Find Rust Early

Early detection can be key when it comes to preventing rust in your car because, if you find it, you can stop it before it gets out of hand. Make sure you inspect under your wheel wells and bumpers often because those are some of the common places when it comes to rust on your vehicle. Additionally, you should look for rust in places where the body components meet and be sure to inspect underneath your vehicle regularly as well. Rust in non-structural body panels can often be easily cut and replaced or treated with a rust inhibitor. Anything remotely structural should be referred to a panel beater unless you have confidence wielding a MIG welder and can do a professional job out of the repair. Do not take to your rusty patches with newspaper, wire mesh or bog filler like a lot of Kiwis used to in the old days.

Covered Storage

Covered and garaged cars will be much less likely to start rusting. A carport will keep your vehicle out of the wet weather while a proper garage will be much more effective, keeping your pride and joy out of weather conditions and moisture. If you are working on a project car, a garage will even keep raw steel panels reasonably safe for weeks on end.

Wash Your Vehicle

While dirt and soot do not cause rust, they can wear down your paint over time which makes your car much more susceptible to rust in the long run. Try and wash your vehicle every few weeks to ensure that it is clean and that the bird droppings and petrol are off the car as well, because they can eat through the paint. Always be sure to clean the underside of the car from time to time as well.

Prevent Rust From Spreading

If you notice that there is rust on your vehicle, you can take action to help make sure it does not spread rapidly and ruin other areas of your car. First, scrape the rust off with a razor blade or a very fine sandpaper. Bigger rusty patches will need to be cut out with a screwdriver or angle grinder, depending on the size and complexity of the area. Then, apply a rust arrestor to help ensure it doesn’t spread any further on your car. People commonly use products like fish oil and POR15 (make sure you wear protective gear while handling these products). Make sure that you let the arrestor dry completely and then apply a primer over the dried area. Lastly, locate the correct shade of pain for your vehicle and purchase some touch-up paint from an auto store to help repaint the spot. If your panels are too far gone for repair – give Dodson’s a shout and get a replacement panel sent out to you.


When it comes to owning a car, one of the last problems you want to deal with is rust and, lucky for you, there are some things you can do to make sure this problem does not happen. If you follow the information provided above, you should have no problem getting the results you want and it will be easy for you to keep the rust away from your car so it looks as good as new.
