8.3. Repair of a hoof of the car
I notice insignificant damages of details of body
Elimination of small scratches
If the superficial scratch also does not attack the metal of the list of body, his repairs are done extremely simply. For the removal of particles of the been left behind one the painting and a wax that it covers lightly rub the area scratched with the briefcase of fine grinding. Rinse the surface prosecuted with the clean water.
The small brush painting on the scratch paints for extern lists of a body. One keeps on presenting that they paint a layer behind a layer until the surface in the scratch does not get the level of a surrounding surface of a painting and the covering of varnish of the list. New painting let's be polymerized inside at least two weeks, we are going to polish soon a transitional surface aflush with a surface of a covering of another part of the list with the use of the most fine briefcase of grinding. In the conclusion they cover the prosecuted surface from the wax.
If the scratch finished a coat of painting, having got the metal of a body and having caused his corrosion, it is necessary to apply another technology of the repair. A penknife splinter had been a powdered rust of the zero, soon prosecute an inhibiting nerve of superficial corrosion to avoid the development of the centers of the corrosion in the future. Covering with the trundle bed prosecuted of rubber or plastic
inhibiting nerve to area damaged difficult putty. If necessary, and it is specially useful in the difficult putty of narrow scratches, for the formation of briefcase completed the difficult putty it can be diluted with the solvent. Before the difficult putty is hardened in the scratch, roll up a fingertip cloth from smooth cotton. Then, having moistened a finger in the solvent, quickly execute for him along the scratch surface of puttied — it will do a lightly concave surface. Now after the difficult putty that hardens the prosecuted scratch can be painted according to the educations it provided cases when the scratch does not attack the metal.
Dents repair
In the moment of the repair of dents a priority is the tug of the deformed surface for aims of his removal at the initial level. The attempts of carrying out the absolute complaisance to the original do not do sense as it is he is even so impossible in view of the violation of the internal structure from metal of the list of body in the moment of the punch. The removal of a concave surface to level approximately 3 mm lower than the surface of the surrounding intact siege of the list of a body is the best. If the superficial dent, his full tug does not do sense in absolute.
In case of what to the concave siege it is possible to manage from a reverse side of the list, it is necessary to try to align a few punches of dent of the hammer with the living creature of the gentle material of inside (rubber, plastic). Exploring a dent, densely hold tight to his face the wooden hammer to compensate for the punch to avoid an excessive flexing on the outside of the metal of deformed list.
If the dent was formed in the siege of two layers of the list or the access to him from a reverse side is impossible for any other reason, it is necessary to apply another technique of a tug. Do several small openings in the concave siege of the list, trying this they appeared in the most buried areas of a dent. Then screw the screws they autocut long in openings, having left his heads that stand out so that it was possible to seize them with passatizha. Now begin to spread out a few claws of dent of screws.
In the next stage of the processing of a dent it is necessary to withdraw of the damaged surface and in the siege of approximately 3 cm of width around him to remain of the covering of varnish and a painting. He is the best of all to execute this work through a mouth of wire or the disc of cleaning established in a cartridge of furadeira electrically, what nevertheless also it prosecutes for an emery paper manually is not less efficient. The final stage of the preparation for the difficult putty — the painting compensates for a protsarapyvaniye
crush the metal to screwdriver or a fragment of an archive or perforating in him small openings to secure the very adhesion from the difficult putty for the metal surface. Besides it is possible to pass the realization from the difficult putty and coloration.
I notice of for damages of corrosion and holes
Through the shkuryashchy or mouth of wire insisted on a cartridge of furadeira electric they withdraw all the aspects of painting of the damaged area and in the siege of approximately 3 cm of width around him. In case of the lack of a possibility of the use of the electric furadeira the work can be executed not less effectively by an emery paper manually.
After the painting removal it is possible to appreciate a corrosion of metal tariff of damage and
to define if there is a sense of beginning the repair or it will be more reasonable to substitute completely the list (if in beginning it is possible). The new lists can buy not too many dispendiosamente as many drivers consider. Very often it seems much quicker and is even more economical to install the new list, of what to repair great damages of a body.
Withdraw of the list damaged all the elements of the finish of a body, except those who can serve of a point of reference of a reconstruction of the original form of the deformed sieges (like the revetment of lighthouses of block, etc.). Or a hacksaw cloth withdraws with the scissors in the metal the metal sieges that everything is freely a suspension, pobremente fixed and desperately damaged by the corrosion. Then do not bend the hammer of the edge of an opening in the interior of the formation of the deepening that will be filled of the difficult putty.
Through a metal brush they withdraw a powdered rust from the damaged metal. There if will be an access to a reverse side of the damaged siege, inhibiting corrosion nerve prosecutes it.
Before silenciador of difficult putty an opening. It can be done, приклепав or when a part of a can corseted itself to the damaged siege of his reverse side or when a wire grill blockaded an opening.
After the opening is closed, the damaged siege can be puttied and painted.
Difficult putty and coloration
The play of the body the difficult putties are produced, nevertheless it is necessary to notice that the briefcase of spackling annexed to plays of the repair of lists of body with a hardener better of all is convenient for works of this sort. To get the smoothness and the fairness of an outline of the surface of puttied, the briefcase has to be applied with the flexible plastic or trundle bed from nylon. The strictly next educations of the producer from the difficult putty (the violation can lead to the incorrect hardening of the weight spackling), implicate the insignificant amount of the difficult putty in a surface from wood or from pure card (carefully they use a hardener).
Apply with the trundle bed to difficult putty in the surface previously prepared of the damaged siege of the list of body. For the realization of a desirable outline of a surface and the level from the difficult putty each palmadinha will pass the trundle bed over the whole repaired surface. As soon as the outline of the surface of puttied is made near to the demanded one, immediately stop applying the difficult putty as, it if are secured, the podlipat will begin to the trundle bed, forming pieces and leaving vyryva in the prosecuted surface. Keep on putting layers of briefcase with intervals approximately 20 minutes until the level of the surface of puttied does not begin to influence lightly the surrounding metal of the list.
After the difficult putty that hardens his excess can be withdrawn with an archive. Besides that the stage of a zashkurivaniye and the grinding of the surface of puttied begin. The best of the whole paper of waterproof emery is convenient with this finality. It is necessary to begin with the paper of thick granulation n ° 180 and besides, constantly reducing the granulosidade, to finish n ° 600. To manage planeness adapted of the prosecuted surface, it is necessary to roll previously the paper up around the grindstone of the dense rubber (a tree or it polyfoams) or to stick in him. In his processing it is regularly and very often necessary to moisten the paper with the water. Such a technology allows to receive the surface prosecuted absolutely smooth and clear in the final stage.
The prosecuted surface has to be surrounded with a ring from pure metal that gets a limit in spite of the fact that gradually the painting coat fails. Powder formed during the grinding washes out the prosecuted superficial clean water, undermining of all that.
Of an aerosol they apply barrel with a fine layer in the surface prosecuted a layer of the light escorvador, a so called in favor presence layer. It will allow to reveal all the defects allowed during the grinding that can be removed covering of his new layer from the difficult putty. Repeat a zashkurivaniye and grinding. Repeat the difficult putty, the processing and the escorvador of a surface before it receiving satisfactorily (in the capacity of the received surface) when it resulted. In the end they wash out the prosecuted superficial water and dry it.
Now the surface is ready to the coloration. The coloration of the car of a barrel of aerosol has to be executed in motionless, dry, hot and not covered in dust air. It more totally satisfy conditions of a condition of the spacious shut and heated room. If circumstances
it forces to execute to color of a body in the open air, it is necessary to treat the choice of convenient conditions of the time very seriously. During the work they withdraw the powder at home, having sprinkled the half of the water of room. If the painting of only a list of a hoof of the car if it executes, covers the intact lists that go round it. This measure for precaution will allow to minimize the effect of the insignificant difference in tones of old and new paintings. Such elements of the finish as of the decorative strips chromeplated, door doorknobs, etc., also is necessary to cover (and it is better to withdraw absolutely). For the protection of the surfaces that are not subject to the use coloration a special insulating tape (an insulating tape of painting) and old newspapers that must be imposed in several layers.
Before beginning coloration of a barrel of aerosol, carefully lift it, soon apply the painting in a proof surface, carrying out the technology of the coloration. Cover the surface prepared to color with a layer of the land. The necessary thickness of a layer is got due to the ground of placing repeated by fine layers. Without feeling sorry for the water, I prosecute a moisture n ° 600 of paper of resistant emery the established surface, trying to obtain his absolute smoothness. Before the initial end that it colors they leave dry ground to us completely.
Put a coat of painting, again trying to obtain the necessary thickness due to his repeated drawing. Begin to color of the center of the repaired siege; doing a hand with a few barrel detours, increase his ray, removing a spiral until it is covered the whole damaged area and a part of an old painting and covering of varnish in the width approximately five centimeters. 10-15 minutes then (not then not to damage the edge of the fresh painting that begins to be secured) after drawing the last coat of painting they separate the covering surrounding lists of a body of the newspaper and an insulating tape. The painting will be finally polymerized inside approximately two weeks then of the aplainação of the transition of the fresh painting to put before they prosecute the surface restored the most fine briefcase of grinding. In the conclusion they apply in the list a layer of the protectant with the wax.
I notice considerable damages of a body
The repairs of serious damages of a body have to be done in the conditions of the workshop of repairs of car specialized in the descarte that there is any necessary equipment.
In the presence of great damages of a body first of all it is necessary to be convinced if there were no shifts of the elements of an able body to affect controllability of the car or in order that there was made the reason of the any increased use of his knots.
In view of the fact that most of elements of a body (a monk's hood, wings, etc.) represent for details that can be substituted separately, his substitution in serious damages does not represent means. As a rule, much more reasonably and more cheaply it seems to find a convenient replaceable element that can be not only in shops of spare pieces, but also in motor heaps that, naturally, there allows to reduce expenses significantly.
