Protected from the winter the most expensive in the car

Protected from the winter the most expensive in the car

Of course any car enthusiast will understand what will be discussed. By far the most expensive part of the car was and will be his body.

Body – the only part that you cannot replace both technical and financial reasons (or rather very difficult and expensive), and the consequences of the destructive effect of corrosion is irreversible. Therefore, in the cycle of preparatory work for the winter, except for the usual tire replacement, refilling windscreen washer “nezamerzayki” and charging the battery, it is necessary to pay special attention to the protection of the body.

Initially from the factory, the metal is pretreated with acidic phosphating, is applied to the soil, which subsequently plastisol polymeric or bituminous mastic. Depending on the quality of the latter, as application technology, determines its service life. As an example, for domestic cars is 2-3 years, for foreign – to ten years.

Struggling with rust

So, without delving into the chemical causes of “rust”, talk about ways of dealing with it:

1. Easier to prevent than to fix. The old adage is true in this case: as mentioned earlier, corrosion process is irreversible, so if the focus is already there, whatever the subsequent cleaning, priming, painting…at this point the corrosion will come back. Timely follow thickness and the presence of coating on the bottom of the body, especially in the lower parts and wheel arches do not allow the exposed metal. Critical point of “no return” will be the appearance of the phosphate coating under the layers of mastic and helmets, which can easily be identified by grayish-white color.
2. Apply protective layers only need to dry the surface and preferably in a warm room. Before proceeding, wait until the metal body is fully warmed up, otherwise required to appear condensate. If you decide to cover with fondant painted surface, it should be matted using fine sand paper because the gloss of a relatively thick layer of mastic will not stick.
3. Plan “minimum” is priming, painting in two to three coats of paint, apply the mastic.
4. Plan “maximum” – it is possible to clean the surface and cover with a layer of “cold zinc”. Of course it is not a hot-dip galvanizing, but is important especially for galvanized body repair.
