First of all, you need to prepare tools and take security measures. When cleaning rust, there will be a lot of dust, so it is recommended to protect the face and respiratory organs. Respirator or mask will be just right. Also need safety glasses and gloves. The car is recommended to cover something with something (most often used protective film and greater tape), while leaving only the working surface. Colorful dust is very small and capable of penetrating even into the smallest slots, so you need to carefully glue the film with scotch.

The next step is to remove paint around rust. To do this, use a dual-action grinding machine. Due to it, it is possible to control the speed of grinding. Suitable sandpaper - №150. With this tool, lacquer, paint and rust (if it is not very hosted). The surface must be aligned so that when moving between the painted and unpainted parts to the touch was smooth.

Next, the machine is taken with a metal grinding circle. With it, the thick layer of rust is removed. It is necessary to do it very carefully, as you can damage the surface of the body. With the help of a special fluid remove rust residues. Most often use orthophosphoric acid. After the rust is completely removed, manually swept the surface with sandpaper No. 120.

After the preparatory work is completed, the primer is applied. Before this, the site is wiping with a solvent or alcohol and the entire approximate surface is stuck, leaving only the work part. The primer is applied in three layers, giving each previous to dry a few minutes. After applying the latter - the car is left to dry for a day.

The progress site is drawn by shallow emery paper and paint is applied in several layers. The edges of the painted area are polished so that the color of the car was monophonic. You can cover the layer of transparent varnish. The car is left to dry out for two days, after that they can be used.
The rust removal process is very simple, the most difficult to paint the car after that, since it is necessary to achieve the car's color to be exactly the painted area.
