The best rust converters for car bodies: rating of the most effective anti-rust agents, comparison table

What is a rust converter for cars?

Corrosion agents have a complex chemical composition. Most of them include an acid and additional components that react with iron oxide.

Corrosion products are transformed into a barrier that protects iron from oxidation.

Zinc converters have a different operating principle. The atoms of the main active substance combine with oxygen and form a film that protects the metal surface. Formulations with zinc are safer.

Acid

Often, rust removers are made based on phosphoric acid. This substance is capable of reacting with oxides, transforming them into salt crystals that are easily separated from the surface. More often, an acid solvent is used to clean the pan and car body.

If the remaining composition is not washed off in a timely manner, it will damage the iron and cause re-oxidation. Less commonly used are hydroxycarboxylic and polybasic acids, as well as tannin.

Thickeners

Thickeners are synthetic compounds that are added to rust converters to increase viscosity. Liquid does not drain from vertical surfaces, so the effect is not reduced. Thickeners do not prevent the penetration of active substances into the deep layers of the oxidized area of ​​the metal.

Corrosion inhibitors

Zinc acts as a corrosion inhibitor. Less commonly, tannin and manganese are added to anti-oxide products. These substances form a film that protects the iron base from temperature changes, moisture and chemical reagents.

Additional Ingredients

Rust converters often include:

• flavorings;
• stabilizers;
• film formers;
• additives, etc.

Additional ingredients enhance the effect of the main components and facilitate the use of the drug.

Tips for use

Anti-corrosion agents with zinc are convenient and effective to use. But in order to eliminate possible problems and achieve an ideal result, it is advisable to remember and put into practice the following tips:

1. Before applying galvanization to an expensive product, it is advisable to test it.

2. 
   Most transducers require the use of gloves.

3. Treatment must be carried out outdoors or in a ventilated area.
4. To stop corrosion, the entire surface must be treated.
5. Remains of the converter and the loose layer are removed with a brush without metal bristles.
6. If necessary, the processing of the metal with the converter is repeated.
7. For preventative purposes, after some time the product should be galvanized again.

You will find all the most important and useful information about rust converters in this section.

Criterias of choice

To choose a good converter, you need to pay attention to the following parameters:

• compound;
• toxicity;
• release form;
• consistency.

Before you buy the drug, you need to evaluate the amount of work. This will help determine the required amount of product.

Main substance

Before purchasing a rust remover, you need to carefully study its composition. Products based on concentrated acids are used for extensive damage, because... these substances are able to penetrate into deep layers. They allow you to quickly remove oxidized plaque. Zinc-based compounds have a milder effect. After their application, it takes a longer time to eliminate the oxides. Then a protective film is formed.

Release forms and consistency

Anti-rust agents are produced in the form of liquids of varying degrees of viscosity, as well as in the form of aerosols. Converters characterized by increased fluidity are well suited for processing horizontal surfaces. Viscous gel-like compositions are convenient to use for vertically located parts. The spray is used to treat hard-to-reach places.

Volume

It is extremely important to correctly estimate the amount of work in order to calculate the required number of converters. Many manufacturers produce anti-rust products in small packages. They are convenient for treating small lesions that have undergone oxidation. If you need to restore a large surface, it is better to purchase the cleaner in a container whose volume exceeds 0.5 liters. Converters that differ in chemical composition cannot be used simultaneously.

Toxicity

All products used to eliminate oxides are toxic. When working with them, you must follow safety precautions. Most formulations need to be washed off. This procedure should not be ignored, because... contact with excess drug will cause poisoning or chemical burns.

• acid agents. An old and proven method that is extremely useful and effective. The main advantage is simplicity and speed of use. We simply clean the area where rust has developed, and then apply the solution there. It is important to calculate the time correctly so as not to overexpose the product, but also not to eliminate it in advance. In general, here you need to follow the instructions;
• rust converter into soil. This is a fairly new modification that helps transform corrosion into soil. At the same time, according to reviews, the use of such solutions is not the safest idea, because the substance can damage the paintwork near the source of corrosion.
