Repair at insignificant damages кузовных details
Elimination of small scratches
If the scratch superficial also does not mention metal кузовной the panel, its repair is spent extremely simply. For removal of particles of the lagged behind paint and a wax covering slightly rub the scratched area with thin grinding paste. Rinse the processed surface with pure water.
Small brush paint over a scratch a paint for external panels of a body. Continue to put a paint a layer behind a layer until the surface in a scratch will not reach level of a surrounding surface of a paint and varnish covering of the panel. Give to a new paint полимеризоваться within at least two weeks, then polish a transitive surface заподлицо with a surface of a covering of other part of the panel with application of the most thin grinding paste. In summary cover the processed surface with wax.
If the scratch has got through a paint coat, having reached metal of a body and having caused its corrosion, it is necessary to apply other technology of repair. A penknife scrape out from a scratch порошкообразную a rust, then process a surface ингибитором corrosion in order to avoid development of the centres of corrosion in the future. Rubber or plastic шпателем cover the processed
ингибитором the damaged area шпаклевкой. If necessary, and it is especially useful at шпаклевке narrow scratches, for formation мелкодисперсной шпаклевку it is possible to dilute pastes with solvent. Before шпаклевка will harden in a scratch, wrap up a finger-tip a smooth cotton fabric. Then, having moistened a finger in solvent, quickly spend it along the puttied surface of a scratch is will make a surface slightly bent. Now after hardening шпаклевки the processed scratch can be painted according to the instructions resulted for cases when the scratch does not mention metal.
Repair of dents
At repair of dents by a priority is вытягивание the deformed surface for the purpose of its deducing to initial level. Attempts to achieve absolute conformity to the original have no sense as it all the same is impossible in view of infringement of internal structure of metal кузовной for the panel at blow. Deducing of a concave surface to level approximately on 3 mm below a surface of the surrounding intact site of the panel of a body is optimum. If the dent superficial, its full вытягивание at all has no sense.
In a case when to a concave site it is possible to reach from a panel underside, it is necessary to try отрихтовать a dent from within blows of a hammer with brisk of a soft material (rubber, plastic). Tapping a dent, densely press to its face sheet a wooden hammer for clearing of blow in order to avoid excessive выгибания outside of the deformed metal of the panel.
If the dent was formed on a two-layer site of the panel or access to it from an underside is impossible for any other reason, it is necessary to apply other technique вытягивания. Make in a concave site of the panel some small apertures, trying, that they have appeared in most заглубленных dent areas. Then screw in apertures long self-cutting screws, having left their heads sticking out so that it was possible to grasp them пассатижами. Now start to extend a dent nippers for screws.
At the following stage of processing of a dent it is necessary to remove from the damaged surface and on a site in width approximately 3 sm round it the rests of a paint and varnish covering. This work is better to carry out by means of a wire nozzle or зачистного a disk established in a cartridge of an electrodrill, also processing by an emery paper manually however is not less effective. The preparation Final stage to шпаклевке — процарапывание cleared of a paint
Metal of a dent a screw-driver or a fragment of a file or drilling in it of small apertures for maintenance of the maximum adhesion шпаклевки to a metal surface. Further it is possible to pass to performance шпаклевки and colourings.
Repair of through corrosion damages and holes
With the help шкурящей or the wire nozzle clamped in a cartridge of an electrodrill, remove all traces of a paint from the damaged area and on a site in width about 3 sm round it. In case of absence of possibility of use of an electrodrill work can be executed not less effectively emery paper manually.
After paint removal it is possible to estimate a damage rate of metal corrosion and
To define, whether there is a sense to start repair or it will be more reasonable to replace completely the panel (if it basically probably). New panels can be got not too expensively as many motorists consider. Frequently it appears much faster and even to establish the new panel more economically, than to repair extensive damages of a body.
Remove from the damaged panel all elements of furnish of a body, except for what can serve as a reference point for a reconstruction of the original form of the deformed sites (such as facing of block headlights, etc.). Scissors on metal or ножовочным a cloth remove sites of metal all freely dangling, poorly fixed and hopelessly damaged by corrosion. Then unbend a hammer of edge of an aperture inside for formation of deepening which will be filled шпаклевкой.
By means of a metal brush remove from the damaged metal порошкообразную a rust. If there is an access to an underside of the damaged site, process it ингибитором corrosion.
Before the beginning шпаклевки muffle an aperture. It can be made, приклепав or having tightened to the damaged site from its return party a piece of a tin or having blocked an aperture a wire grid.
After the aperture will be closed, the damaged site can be puttied and painted.
Шпаклевка and colouring
The set кузовных шпаклевок is issued, however it is necessary to notice that for of this kind works is better paste with a hardener approaches applied on sets for repair кузовных panels шпаклевочная. To reach smoothness and correctness of a contour of the puttied surface, it is necessary to put paste flexible plastic or nylon шпателем. Strictly following instructions of the manufacturer шпаклевки (infringement can lead to wrong hardening шпаклевочной weights), get mixed up insignificant quantity шпаклевки on a pure wooden or cardboard surface (carefully use a hardener).
Шпателем put шпаклевку on preliminary prepared surface of the damaged site кузовной panels. For achievement of a desirable contour of a surface and level шпаклевки each dab шпателем should pass through all repaired surface. As soon as the contour of the puttied surface becomes close to demanded, immediately stop to put шпаклевку as it, stiffening, will begin подлипать to шпателю, forming lumps and leaving вырывы on a processed surface. Continue to put layers of paste with intervals about 20 mines until level of the puttied surface not begins to act slightly over surrounding metal of the panel.
After hardening шпаклевки its surplus can be removed a file. The stage зашкуривания and polishings of the puttied surface further begins. Is better for this purpose the waterproof emery paper approaches. It is necessary to begin with a coarse-grained paper №180 and further, consistently reducing granularity, to finish №600. To reach adequate planeness of a processed surface, it is necessary to wrap up preliminary a paper around бруска from dense rubber (a tree or polyfoam) or to paste on it. In the course of processing it is necessary to moisten a paper with water regularly and often. Such technology allows to receive absolutely smooth and equal processed surface at the final stage.
The processed surface should appear surrounded with a ring of pure metal which comes to an end with gradually coming to naught paint coat. Wash out the processed surface pure water, washout from it all dust formed during polishing.
From aerosol баллончика a thin layer put on the processed surface a layer of a light first coat, a so-called proattendance layer. It will allow to reveal all defects admitted during polishing which can be eliminated a way покрывания their new layer шпаклевки. Repeat зашкуривание and polishing. Repeat шпаклевку, processing and a first coat of a surface before reception satisfactory (on quality of the received surface) result. On termination of wash out the processed surface water and dry up it.
Now the surface is ready to colouring. Colouring of the car from aerosol баллончика should be spent at motionless, dry, warm and not dusty air. Most full meet the given requirements of a condition of the spacious closed and heated premise. If circumstances
Compel to spend body colouring in the open air, it is necessary to concern a choice of suitable weather conditions very seriously. At work indoors remove a dust, having sprinkled a floor of a premise water. If painting only one panel of a body of the car is spent, cover the intact panels surrounding it. This safety measure will allow to reduce to a minimum effect of insignificant difference in tones of old and new paints. Such elements of furnish as the chromeplated decorative strips, etc., also it is necessary to cover door handles (and it is better to remove absolutely). For protection of surfaces not subject to colouring take advantage of a special sticky tape (a painting adhesive tape) and old newspapers which should be imposed in some layers.
Before starting colouring from aerosol баллончика, carefully stir up it, then put a paint on a trial surface, fulfilling technics of colouring. Cover the surface prepared for colouring with a layer of earth. The demanded thickness of a layer is reached at the expense of repeated drawing of a ground by thin layers. Without feeling sorry some water, a moisture resistant emery paper №600 process the grounded surface, achieving its absolute smoothness. Before starting definitive colouring allow to a ground to dry up completely.
Put a paint coat, again achieving a demanded thickness at the expense of its repeated drawing. Colouring begin from the centre of a repaired site; making a hand with баллончиком circular motions, increase their radius, moving on a spiral until there will be covered all damaged area and a part of an old paint and varnish covering for the width about five centimetres. Later 10–15 mines (not later not to damage edge beginning to stiffen a fresh paint) after drawing of last paint coat separate covering surrounding panels of a body of the newspaper and a sticky tape. A paint definitively полимеризуется within approximately two weeks then for smoothing of transition from a fresh paint to put earlier process the restored surface the most thin grinding paste. In summary put on the panel a layer of protective means with wax.
Repair at considerable damages of a body
Repair of serious damages of a body should be spent in the conditions of a specialised repair truck at which order there is all necessary equipment.
In the presence of extensive damages of a body first of all it is necessary to be convinced, whether has occurred displacement of elements of the body, capable to affect controllability of the car or to become the reason of the raised deterioration any of its knots.
In view of that (the cowl, wings, etc.) represent the majority of elements of a body of a detail to replace which it is possible separately, their replacement at serious damages is not represented expedient. As a rule, it appears to find a suitable replaceable element much more reasonably and more cheaply, to find which it is possible not only in shops of spare parts, but also on automobile dumps that, naturally, allows to cut down essentially expenses.
