22.4. Repair of insignificant damages of a body
Processing of scratches of a body
If the scratch superficial also does not reach some metal, wipe area round a scratch обновителем paints or fine-grained abrasive paste. Wash out a surface pure water. Put on a scratch a brush a thin paint coat and allow to it to dry up. Continue to put a paint to level of a paint and varnish surface. Allow to a paint to harden within 2 weeks and then polish. Polish a site of a surface of a body by means of wax paste.
If a scratch, having damaged a paint, has got into body metal, a tip of a sharp knife remove a rust from a scratch. Put the rust converter according to the instruction. Шпателем put on a scratch шпаклевочную paste. After its full drying paint over and polish the damaged site.
Repair of dents in a body design
At deep cave-in of elements of a design of a body first of all try to curve a dent before the maximum approach to a body normal form. Body metal in a blow place is exposed вытягиванию therefore the complete recovery of the initial form is impossible. Optimum it is considered dent alignment approximately on 3 mm below level of a surrounding surface. If there is an access to a dent inside, it is necessary to correct accurately its hammer with wooden or plastic the brisk. During this operation it is necessary to press densely to an outer side of corrected area approaching on the size wooden брусок. It is required for amortisation of blows of a hammer and prevention выгибания to more extensive area. If the dent is in that area of a body where access from an underside is complicated or impossible, drill in the deepest points of a dent some small apertures, in them screw self-cutting screws and extend a dent by means of flat-nose pliers for acting heads of screws.
Remove a paint from the damaged area and on distance of 20 mm round it. It is the most easier to make it a wire brush or an emery paper, насаженной on a circle fixed in an electrodrill. After dent alignment put on it a layer шпаклевки, paints and polyroles.
Шпаклевка and body painting
At performance шпаклевочных works it is necessary to have wide flexible plastic or nylon шпатель for giving of smoothness of a surface шпаклевки. Level шпаклевку on the damaged site of a body so that to give it the demanded form and smoothness. As soon as it was possible to achieve approximately demanded contour, stop to smooth down шпаклевку шпателем as at too long smoothing down it will start to harden, stick on шпатель and to roll down, therefore the surface will be damaged. To put the subsequent, more thin layer шпаклевки follows after drying of the previous layer until level шпаклевки will not start to act slightly over a processed site. After hardening шпаклевки its surplus is necessary for removing a metal scraper or a file. The further processing spend, using an emery paper set. Begin processing by a coarse-grained emery paper, then fine-grained. Emery paper have on flat wooden бруске, differently it is impossible to achieve an equal surface. At a finishing stage of polishing it is necessary to moisten a waterproof emery paper with water periodically. It will give to the processed puttied surface special smoothness. The puttied dent should appear surrounded on perimetre a layer of pure metal. For removal of a dust and fats wash out a processed site water and wipe degreasing means. Raise dust on a site a thin layer of a light ground. It will help to reveal all defects admitted at processing in шпаклевке. Level them by means of a new layer шпаклевки and again зашкурьте a surface.
After that the repair area is ready to final painting. Aerosol drawing of a paint should be spent in warm, dry, windless and easy atmosphere. At painting carrying out indoors it is necessary to moisten a floor of a working platform with water for hit prevention in dust air. At colouring only one panel other parts of a body should be covered from hit on them paints by the newspaper attached by a sticky tape. Before first coat drawing carefully mix it, put on a trial surface and achieve that it laid down in regular intervals. Put a thick layer of a first coat for what put some thin layers. Polish the grounded surface a waterproof emery paper. Thus do not forget сбрызгивать ground area water and periodically to moisten in water an emery paper. Before the further painting dry up a processed site. Put a paint coat a spray. The necessary thickness of a paint coat is reached by drawing of several thin layers. Colouring is necessary for beginning from the centre of a processed surface and to move to edges back and forth motions until all painted surface and area on distance about 20 mm round it will not be painted. A protective film and newspapers remove later 10–15 minutes after drawing of last paint coat. Give the chance to a fresh paint to harden within at least two weeks, then with the help обновителя a paint or thin abrasive polishing paste level edges of the painted area to level of an old paint. Polish a surface.
Repair of considerable damages of a body
At considerable damages of a body and requirement for replacement of a considerable part of details work is necessary for spending on a car repair shop. If body damages are received as a result of strong blow, it is necessary to check up the sizes of a body. Durability and the form of all body can change as a result of damage of separate details. Discrepancy to norm прочностных characteristics and the sizes of a body can appear the reason of impossibility of normal driving. Besides, non-uniform pressure will influence a steering, the engine, transmission and can be at the bottom of the raised deterioration and infringement of their functions.
