This is especially important when buying a used car, and not only domestic, but also imported production, as in the process of car operation the appearance of corrosion on the body is inevitable.
Anticorrosion treatment can be carried out on your own. For this purpose, special compositions are used that prevent moisture and aggressive substances from penetrating under the applied layer, thus protecting the metal from corrosion centers. Such compositions include mastic and antigravity.
You should remember that rust and corrosion are not quite the same, although many people think otherwise. Rust is more of a type and product of corrosion, because it is iron oxide, which is formed as a result of the destruction of the metal. Not only moisture and unstable natural temperatures are responsible for that. Such a state of metal often occurs under the influence of chemical or electrochemical factors.
It is also quite logical that the body of the car suffers most from corrosion, and especially – its bottom. Therefore, it most often has to be repainted and renewed. The corrosion itself can be dry and wet. That is, the first can occur without moisture. Steel and iron parts just fade.
The lower parts of the car body, including wheel arches, are the most vulnerable part of the body to corrosion. Mechanical exposure to stones, sand and gravel flying from under the wheels causes damage. Road reagents, moisture and dirt get into them and lead to corrosion. This is why timely corrosion treatment of the lower body parts protects against damage, helping to extend the life of the body.
How much does rust repair cost?
If you are lucky to have rust on a small part of your car, then the cost will start at 60$. That is how much new metal panels cost. It is possible to repair big sections of metal. If you need the whole body repaired, then it will be somewhere from 200$ to 2000$.
Can wheel well rust be fixed?
Corrosion must be removed with a metal brush or sandpaper. This must be done very carefully so as not to leave even the slightest rust spot. The fact is that even the smallest rust spots will continue to oxidize the metal, because the oxide films themselves contain enough oxygen to continue the reaction.
Special chemicals (solvents, rust cleaners) provide significant assistance in removing rust on the machine.
Do not forgetabout safety when using them, as these substances are very aggressive, wear personal protective equipment – goggles and rubber gloves.
Do not forgetto carefully remove traces of chemical cleaners from the surface after treatment. Rinse the treated areas with water and wipe them dry with a cloth.
It is essential to do this, as the active chemicals left on the metal surface will begin to destroy the protective paint coat, thus opening the access of moisture to the metal, will begin an oxidizing reaction in which these chemicals, in addition, will be catalysts.
Is it worth fixing rust on a car?
Corrosion can affect any metal parts of the car, even without looking at their age. Large amounts of wet rainfall, adverse weather conditions – and so the enamel begins to peel off, and its place is boldly corrosion. Also, the reason can hide behind incorrect technology of painting on a car surface.
The most severely affected by rust is the car body and the bottom. If the problem is not solved in time, the metal may rot completely which makes the car dangerous to drive.
Everything depends on the rotten section. It is easy to do some dent repairs. However if your car is mostly rotten and has rust holes, cosmetic repair will not make any difference and will be extremely costly.
How much does it cost to repair a wheel well?
From the first day of use any car is exposed to destructive factors such as atmospheric precipitation, seasonal temperature changes, poor pavement condition, accidental or intentional misconduct by the driver. The influence of these factors on the body and suspension accelerates the aging process of the vehicle and its gradual destruction. Wheel arches take the first hit.They suffer not so much from water and mud, snow and ice, as from impacts from gravel and sand flying from under the wheels. This kind of gravel and sandblasting is a serious problem for the body.
If the size of a rust area is small, works can cost you approximately 200$-300$. And if corrosion has covered almost all bottom, you can pay way more than that.
If a small area is damaged by corrosion, you can tackle the rust yourself.
You’ll need to remove the corrosion:
- A rust converter (to put it simply, an acid that will corrode).
- Metal brush.
- Antigravity (a coating applied after rust removal).
So this is the most economical option, if, of course, you and the equipment on you.
