Are you super afraid of rust coming and attacking your car? If your car has had the right undercarriage treatment, you may not need it. But do you have it? Rust is a big problem with many things that are made of iron or things that include ferrous material. The chemical connection between iron and oxygen which makes the iron reddish, yellowish and brownish in color and causes the material to break off into small pieces. In this way, the oxygen can now penetrate further and attack a new area. This means that e.g. your car will constantly become weaker at the points where the rust has attacked.

At rust protection, they can help with an anti-rust treatment – that is, give your undercarriage a treatment so that oxygen cannot come into contact with the iron that your car is largely made of.

Of course, it is not only cars that can rust, but you see it on all sorts of different objects that contain iron. Sometimes you also see it on products that should otherwise be stainless. In this case, rust has spread from untreated iron onto the otherwise treated metal. If there is water in an area for a long time, this can also penetrate in some cases because the oxygen in the water has been able to connect.

And then a little bonus info here at the end. Rusty iron can be recycled to the same extent as normal iron. When you remelt the iron, you remove the compounds that the oxygen had otherwise formed with the iron.

The car’s weak points and risk areas doors, tailgate and bonnet

It is easy to understand that the hood is exposed to stone chips, but it is equally important to inspect the edges of the doors. The lower edge of the door is exposed to tire spray, while the side risks being hit against a wall or the like, which causes rust-promoting wounds in the paintwork. Accidentally squeezing something unyielding can have the same result at the tailgate. It is recommended to regularly wash the door openings and door leaves and at the same time inspect for damage.


The most exposed part of the car. Details to be extra vigilant about are spring packs, spring cups (the upper attachment point for springs and struts), support arms, link arms, steering rods and the bottom plate itself. Car manufacturers are increasingly using light metal in the wheel suspensions. Many cars have plastic protective covers under the car to reduce and control turbulent air and reduce air resistance. Peeking behind the plastic covers requires some kind of knowledge of how they are dismantled.
