Which rust converter is better?

Rust converter is more in demand among motorists, since the car body inevitably becomes affected by corrosion over time. The product belongs to the category of modifiers. Converters differ in composition, price, and application features. Some of them require rinsing off after application, while others do not. Of course, the consumer would like to purchase the most powerful and effective rust converter, so it makes sense to consider in detail the most popular products of this type.

What to pay attention to

The effectiveness of the action depends on the composition of the modifier. When choosing a product, it is better to give preference to products from well-known manufacturers, whose reputation has been formed over many years. It is also important how toxic the rust converter is. The latest generation products are ahead of their competitors in this indicator.

Another criterion is the release form. Modifiers are sold in aerosol cans, gel and liquid form.

Compound

Rust converters are divided into single-component and multi-component compositions. It is the composition that determines the scope of application of the product:

• Simple.It is a one-component product whose active ingredient is phosphoric acid. The product reacts with rust and prevents the further spread of corrosion. Remains of unreacted acid must be removed. Otherwise, the rusty layer will appear again.
• Multicomponent. In addition to phosphoric acid, this product also contains zinc and manganese salts. Due to this, a protective barrier is created, and the acid that has not reacted is neutralized.
• Primer. In this case, the buyer is offered a set of two solutions. One is acidic, the second is salt-based. Both compositions are mixed and applied before painting the car. The mixed solution is suitable for use for 5 days.
• On a paint and varnish basis. This is a neutralizing composition with additives of inhibitors that prevent the development of corrosion. After application, the converter forms a thin film on the surface. The protective layer should be updated regularly.
• Film-forming converter based on petroleum products. The product contains solvents, petroleum resins, various additives and inhibitors. Also requires periodic updating.

New generation film-forming agents contain a water-based solvent; they provide protection not only from corrosion, but also from mechanical damage.

Efficiency

When evaluating rust converters, it is impossible to say unequivocally which one will better protect the metal from corrosion. It is necessary to consider the scope and conditions of application. Efficiency depends on whether the internal or external part is to be treated, at what angle it is located, and what the affected area is. Acid agents that penetrate to a significant depth (up to 300 microns) are considered more powerful.

Experts recommend the use of modifiers containing manganese and zinc oxide. During the tests they showed the greatest effectiveness. After applying such a composition, an effect comparable to alloying is achieved. To improve effectiveness, modern formulations add corrosion inhibitors, additives to suppress foam formation, and thickeners that retain the product on the surface longer.

Toxicity

The most powerful agents are also more toxic - this is natural. In this sense, an acid-free converter has the advantage of lower toxicity. When working with a product based on orthophosphoric acid, increased safety measures will be required. The composition must be applied in a ventilated area or outdoors. It is better to protect the skin and mucous membranes from the effects of acid with a respirator, goggles, and gloves.

Manufacturer

The rating of the best products used to combat rust is compiled based on the results of surveys and expert assessments. Companies such as KUDO, KERRY, Permatex, Eltrans, RUSEFF, Agat-Avto, ASTROhim and others have firmly taken their positions in this list.

Best Liquid Converters

Liquid converters are widely available on the market. Among the most popular brands:

1. "Tsinkar" from "Agat-Auto" – liquid composition with zinc, produced in a 2.8 liter bottle. Recommended for use in heated rooms. After application, it transforms rust and forms a durable coating on the surface.
2. "Antiruster" by ASTROhim – an economical product with zinc ions. Before application, it is recommended to remove loose rust layers. Works at temperatures above C. Requires rinsing after finishing work.
3. "NO RUST" from LAVR acid-based. Quickly removes rust.Requires careful handling. It should be applied avoiding contact with painted surfaces.

The best in the line of liquid products is the Tsinkar modifier. In most ratings, this product occupies a leading position. "Tsinkar" is also available in plastic packaging with a spray bottle.

Best Gel Converters

The gel is convenient to apply to parts located at an angle or vertically. TOP converters produced in gel form:

1. "Rust converter with structural modifier" from KUDO. Suitable for use on ferrous metals. Apply with a brush. It has a thick consistency, which makes consumption economical, despite its small volume.
2. "Rust converter with structural modifier" from KERRY. The gel formula with zinc guarantees the destruction of rust and provides further protection by forming a film on the surface. The composition is 2 times more effective than a conventional modifier.
3. "Rust Treatment" by Permatex. The American modifier converts rust into primer in a few minutes, is conveniently applied to any surface and is evenly distributed.

All converters in the form of a gel are economically consumed and convenient to use. The listed modifiers have already won the trust of customers.

Best Aerosol Converters

The aerosol form ensures quick application and does not require additional equipment. Popular aerosol rust converters:

1. "No-Rust" 2X HG5721 from Hi-Gear. The best aerosol converter, according to experts, is produced by a well-known American company. Serves to eliminate rust and further anti-corrosion protection.
2. "EL-0702.06" from Eltrans. Russian-made aerosol for those who are looking for a high-quality budget product.A 650 ml cylinder costs an average of 200 rubles. The composition dries quickly and has good adhesion. Apply in 2 layers.
3. “Rust to soil converter” in the form of an aerosol from G-POWER. A German product of excellent quality in a small bottle that is convenient to carry with you. Before treatment, it is recommended to clean and dry the surface.

Aerosols are stored for a long time after opening and can be reused with a long break. Spraying makes it possible to apply the composition in a thin and even layer.

The best paste converters

Corrosion removal pastes have a wide range of applications. They are used to remove rust from metal structures, railway equipment, lifts, weapons, metal fences, and automobile bodies. Most often they buy:

1. "KPPS Super" 50 g. The product professionally removes pockets of corrosion on metal elements. The composition includes inorganic acids and zinc salts. The paste is fast-acting and provides subsequent protection of the metal.
2. "KPPS rust remover." The paste is sold in a large jar weighing 250 g. Its use makes it possible to reduce metal processing time, improve adhesion before further painting, and prevent the spread of corrosion in the future.

Due to their thick texture, pastes act concentratedly, cleaning the surface not only from rust, but also from mineral deposits and scale. The converter is easily removed from the surface after the reaction is complete.

Which converter to choose

To choose the right rust remover, several criteria are taken into account. It is necessary to take into account the location of the surface (horizontal, vertical, at an angle). It also matters whether the rust is inside or on the outer surface.Open areas require more reliable anti-corrosion protection.

The method of application plays an important role. Some people find it more convenient to use a brush, while others prefer spraying with an aerosol. And finally, the purpose of use is taken into account. If you just need to remove a layer of rust, use acid-type converters. Acid-free products are often used as a primer before painting.

Rust converters help extend the life of metal products and parts. Most products of this type not only rid the surface of corrosion, but also provide further protection. Over time, the protective film deteriorates and will need to be renewed. The choice of modifier depends on the purpose of use, the location of the surface, and preferences for the application method.
