11.2. Care of body elements and paint and varnish covering

It is necessary to remember that the main factor defining selling cost of the second-hand car, the condition of its body is. Procedures of care of body panels are extremely simple, but should be carried out on a regular basis. Negligence to the smallest mechanical damages and defects of a paint and varnish covering can lead to fast development of corrosion and need of performance of expensive body repair. It is important to check also regularly a condition of the surfaces hidden from a look and details, such as arches of wheels, the lower part of partitions of an impellent compartment, etc.

Base procedure on the care of a body of the car is its sink (see. A wash of the car), preferably plentiful quantity of water, submitted under pressure from a hose. Rather powerful stream easily softens and forces down the dried-up dirt and that is important, allows to avoid damage of a paint and varnish covering at a friction about it separate grains of sand and other abrasive particles. Do not forget to wash out also an arch of wheels and bearing elements of the bottom of the car. Strangely enough, the best time for performance of a sink of elements of a suspension bracket and the bottom of the car is damp rainy weather when the most part of the accumulated mud deposits is washed away automatically during movement. Try not to miss possibilities and, taking an opportunity, make external survey of the components located under the car.

Having completely washed away dirt from a paint and varnish covering, wipe surfaces of body panels soft suede, returning to polishing initial shine. Processing of surfaces by a polyrole containing wax provides additional protection of a paint and varnish covering against atmospheric influences and allows to restore locally lost polishing. Remember that tarnishing of a paint and varnish covering is connected with negligence to a regular wash of the car more often.

It is necessary to make wax polishing of body panels approximately time in half a year. Paint and varnish coverings of the metallic type need special leaving with application of special, not containing abrasives of polyroles. Try to check regularly passableness of drainage and ventilating openings of body panels. Do not forget to wipe from time to time some glass, by means of special cleaning structures deleting from their surface a road film. At all do not use for processing of glasses polyroles containing wax or means for care of the chromeplated elements of furnish.

Once a year, or through each 20 000 km of run it is necessary to make check of a condition of an anticorrosive covering of the bottom of the car. Previously it is necessary to subject the car bottom, including an impellent compartment, steam cleaning during which multilayered oil deposits, sticky шлам and dense dirt especially well are removed. If possibility of application of steam cleaning is absent, it is necessary to process by means of a brush surfaces of components subject to cleaning by one of a set of solvents let out now.

The last method should not be applied on cars, the anticorrosive which covering of the bottom has a wax basis.

Such annual survey of the car should be made before the beginning of a winter season after a good razmachivaniye of mud and oil deposits in the conditions of the increased humidity, characteristic for an autumn season. The damaged anticorrosive covering should be immediately restored. In an ideal, once a year it is necessary to make complete anticorrosive processing of the car at which the protective structure downloads in a cavity of door panels, thresholds, box-shaped sections of bearing body elements and other available volumes.

The last does not treat panels and the sections subjected to complete anticorrosive processing and zagermetizirovanny industrially.

Remember that continuous finding of external and internal components of a body and car furnish belong to number of the factors accelerating development of corrosion in the humidified condition; the increased relative humidity of air, especially at temperature is higher than a freezing point and in districts with the raised level of pollution of the atmosphere; the raised air temperature (the increased temperature renders special influence on development of corrosion of badly ventilated elements); the increased impurity of air (saturation by salts and acids); salt application for paving processing in winter months (special attention give to regular cleaning of wheel arches and bottom elements.
