Restore areas affected by corrosion immediately upon detection of its traces on the paintwork or in places where the mastic has peeled off.
The most radical rust removal method is mechanical, although it is more laborious. The combination of chemical and mechanical treatment of the affected areas is the most appropriate and effective.
Restoration of areas affected by corrosion, carry out in the following order.
For easier rust removal, moisten the damaged area with mineral spirits or auto cleaner «Omega 1». Remove corrosion products with metal brushes, scrapers of various shapes, spatulas, grinding wheels and cloth- or paper-based skins.
Clean to a metallic sheen of damage from rust, old primer and paint, bituminous or plastisol coating.
Rinse cleaned areas with water, dry and degrease.
Apply with a brush a phosphating agent of the type «phosphator».
Dry the treated surface for 25–30 minutes at 18–20°C.
On the prepared surface, apply a quick-drying primer of a phosphating or passivating type with a low drying temperature, such as VL-2 or VL-08 (phosphating primer, drying temperature 15-20°C, drying time 24 hours) either GF-073 or NTs-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 control of structural corrosion is the most time-consuming and costly. It consists in inspecting the car, the necessary disassembly and replacement of individual affected body elements or the removal of damaged areas and welding overlays to these places. The installation of overlays 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 life of the body by another 10–15 years.
