11.4. Repair of insignificant damages of a body

THE GENERAL DATA

Processing of scratches of a body

If the scratch is superficial and 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 give the chance to it to dry up. Continue to put a paint until the scratch will not be made even to surrounding surface. Give the chance to a paint to harden within 2 weeks, then polish the put paint coat to level with a paint surrounding a stain. In summary 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, that, using a tip of a sharp knife, remove a rust from a scratch. Put the rust converter according to its instruction. Further 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 back 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, follows accurately выстучать its soft hammer with a wooden or plastic head. During this operation it is necessary to press densely to an outer side of tapped area corresponding wooden брусок. It is required for amortisation of blows of a hammer and for предотвра щения выгибания to more extensive area. If the dent is in that area of a body where access from an underside is complicated or impossible in the deepest points of a dent drill not how many small apertures, in apertures screw up 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. Most easily it can be executed, using a wire brush or an emery paper, насаженную on a circle fixed in an electrodrill. After dent alignment put on it a layer шпаклевки, paints and polyroles.

Repair of the rusted apertures or holes in a body design

Remove a paint from the damaged area and approximately on 20 mm round it. Using a metal brush, clear a showered rust from a surface of the bared metal on the damaged area. Process the damaged area the rust converter according to its instruction. Close an aperture from a rust or a hole a metal grid or a strip of an aluminium foil. Cut out approximately соответству ющий to the form of an aperture a grid piece, enclose it in an aperture so that its edges did not act over level of the panel surrounding an aperture. Fix it by means of several lumps шпаклевочной pastes on perimetre. Using the screw-driver handle, level the grid ends so that it densely adjoined to body metal. Further make шпатлевку, painting and polishing of the damaged site of a body.

Шпатлевка and body painting

At performance шпаклевочных works it is necessary to have wide flexible plastic or nylon шпатель for surface giving шпаклевки smoothnesses. Alignment шпаклевки on the damaged site of a body make 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, since. At too long smoothing down it will start to harden, stick on шпатель and to roll down, therefore the surface will be damaged. Drawing of subsequent, more thin layer шпаклевки should be made after drying of the previous layer and so until level шпаклевки will not start to act slightly over level of a processed site. After hardening шпаклевки its surplus is necessary for removing металличес ким a scraper or a file. The further processing make, using an emery paper set. Begin processing with use of a coarse-grained emery paper and in the subsequent pass to the fine-grained. An 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 gives to the processed puttied surface special smoothness. The puttied dent should appear surrounded on perimetre a layer of pure metal. For removal from the processed site of a dust and fats wash out a processed site water and wipe a degreasing solution. Raise dust on a site a thin layer of a light ground. It will help to reveal all defects admitted at processing in шпаклевке. The found out defects level by means of a new layer шпаклевки and again зашкурьте a surface. Continue this procedure before reception of an ideal 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 shake up capacity with it, put a first coat on a trial surface and achieve that it laid down in regular intervals. Put a thick layer of a first coat by drawing of several 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 colouring dry up a processed site. Paint coat drawing is made by a spray. The thickness of a paint coat is reached by drawing of several thin layers. Colouring is necessary for beginning from the centre of painted area and to move to edges vozvratno-on ступательными movements until all painted surface, and also 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 in a current at least 2 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.
