Restoration of areas affected by corrosion (Renault Symbol 1)

Repair areas affected by corrosion immediately upon discovering traces of corrosion on the paintwork or in areas where the mastic has peeled off.

The most radical method of removing rust is mechanical, although it is more labor-intensive. A combination of chemical and mechanical treatment of the affected areas is the most appropriate and effective.

Restoration of areas affected by corrosion is carried out in the following order.

To facilitate rust removal, wet the damaged area with white spirit or Omega-1 car cleaner. Remove corrosion products with metal brushes, scrapers of various shapes, spatulas, grinding wheels and sandpaper on a fabric or paper base.

Clean damaged areas from rust, old primer and paint, bitumen or plastisol coating until they have a metallic shine.

Rinse the cleaned areas with water, dry and degrease.

Apply a phosphating agent such as "Phosphator" with a brush.

Dry the treated surface for 25–30 minutes at a temperature of 18–20°C.

Apply a quick-drying phosphating or passivating primer with a low drying temperature to the prepared surface, such as VL-2 or VL-08 (phosphating primer, drying temperature 15-20°C, drying time 24 hours) or GF-073 or NC-097 (passivating primer, drying temperature 15-20°C, drying time 4 hours).

After the first layer has dried, apply a second layer of primer. Let it dry slightly and paint with decorative enamel.

Effective combating of structural corrosion is the most labor-intensive and expensive. It consists of inspecting the car, necessary disassembly and replacement of individual damaged body elements or removing damaged areas and welding pads to these places. Installing pads does not solve the problem, but only somewhat slows down the development of through corrosion of the body. Replacing damaged elements from spare parts or new elements will extend the service life of the body for another 10-15 years.
