Zinc primer for cars: features of use and rating of the best
Content
Often a small chip or scratch is enough to cause rust. Therefore, for additional protection of the car, a zinc primer is used - a special composition presented in the paint format.
Corrosion is the gradual destruction of metal. Zinc primer for cars provides reliable protection of the body from external influences. The special composition helps to avoid the formation of rust and prepare the car for painting.
What is zinc primer
The fact is that the standard painting of the car does not exclude corrosion. Often a small chip or scratch is enough to cause rust. Therefore, for additional protection of the car, a zinc primer is used - a special composition presented in the paint format.
Main components:
- fine flakes, dust or zinc powder;
- resins or polymers;
- solvent.
The procedure is called cold galvanizing. The substance is applied to the body and individual elements before paintwork.
Application of zinc primer
Zinc primers are used for the car, when working on metal and rust. No less widespread material received in construction.
The tool is used for processing metal structures:
- bridges;
- industrial facilities;
- flyovers;
- cisterns;
- pumping and sanitary equipment;
- pipes;
- oil pipelines, etc.
Galvanizing prevents corrosion. With external exposure, zinc begins to oxidize, preventing the destruction of the treated surface.
Body primer
At the same time, the soil itself is “cemented”, forming a reliable protection of metal structures from dirt, temperature changes and moisture.
Zinc-containing primers for metal for cars: rating of the best
Zinc primers for metal for cars contain up to 95% of the active substance - zinc.
Additional components are divided into 2 categories:
- Organic - film formers like polyurethane or epoxy. Such products are distinguished by good electrical conductivity, as well as sacrificial protection through the polarization of steel.
- Inorganic - dielectrics, polymers or alkaline silicates act as "fillers".
In addition to zinc, the spray may contain magnesium, aluminum and red lead. They affect not only the protective properties of the primer, but also the color of the coating. The rating of products includes products that give a neutral gray tint.
Rust converter ELTRANS to primer with zinc
In the ELTRANS line there is a rust converter with zinc, which replaces the primer for the car. The tool is focused on the radical elimination of corrosion immediately before painting.

How to apply zinc primer
Liquid zinc is produced in cans and aerosols. In the first case, you will need to study the instructions. The latter option is more convenient, because the soil is already ready for work. Just enough to shake the can.
Features of preparing for the use of a primer with zinc for cars:
- the presence of corrosion - eliminate the existing rust, if necessary, use the converter;
- new part - clean with detergents;
- old or previously painted element - completely remove the paint.
Immediately before spraying, the work surface must be washed, thoroughly dried and degreased. Foreign parts should be protected with a special cover or masking tape.
Car polishing
Try to distribute the product evenly. The number of coats, drying time and paint application time depend on the brand of primer.
Primer with zinc: reviews
Reviews on a primer with zinc for cars in cans:
- Ivan, St. Petersburg: I regretted that I bought the Eltrans rust converter. The composition is not bad, but the sprayer is just terrible. Runs and runs through time. All smeared while painting the car.
- Yuri, Perm: I purchased a zinc primer "Bodi" for processing welding seams. I liked that it dries quickly and melts, but does not fade. Although if you take it, then keep in mind that gasoline, thinner or solvent will easily wash it off.
- Andrey Arevkin, Moscow: The idea with aerosol primer is interesting, but you have to constantly shake the can. In general, the purchase is satisfied. It's been a few months now and no defects.
Buyers note that the quality of more expensive products is close to budget brands. The exception is highly specialized tools focused on solving specific problems. When looking for a suitable primer, pay attention to the concentration and dispersion of zinc.
