Repair minor damage to body panels
Restoring easily scratched paintwork
If you scratch the surface and does not affect the metal body panels, restoring paintwork is done very simply. To remove particles flaking paint and wax coating lightly rub the defective portion of the fine grinding paste. Rinse the treated area with clean water.
Using a small brush fill scratch paint of the same type and color as that used for the staining of the panel. Continue to put a paint layer by layer up until the bottom of the crack is equal to the surface of the surrounding paint body panels. Allow the paint cure for at least two weeks, and then carefully abrade transition zone with fine grinding paste. Finally, treat the reconstituted panel wax.
If the scratch has penetrated through the paint and metal panel reached, causing the development of corrosion, the refurbishment should be carried out by other technologies. Penknife to scrape the bottom of the scratch rust powder, then treat the damaged section of a corrosion inhibitor to prevent its development in the future. With made of hard rubber or nylon applicator fill the damaged area glyantsovochnogo filler type. If necessary, which is especially useful for eliminating narrow deep furrows coat can be diluted with a special solvent. Before the plaster hardens within the crack, wrap the tip of your finger with a soft cotton cloth, soak it in a solvent, and quickly spend along the scratch. As a result, the surface becomes slightly concave. Now, after hardening putty, the treated area can be painted with that described in the first part of this sub-section technology.
Repairs dents
When repairing deep dents primary task is pulling the deformed surface body panels in order to restore its original shape. Note that it makes no sense to achieve one hundred percent compliance with the original, the more that it is unattainable due to irreversible damage of the internal structure of the metal at the moment of impact. It will be enough to withdraw the deformed surface layer located 3mm below the surface of the surrounding undamaged part of the panel. Note: If the shallow dent, pulling it all becomes meaningless.
If a deformed portion can be matched with the back side of the panel should try Align panel inside, metal tapping a hammer with soft brisk. In doing so, the front side of the damaged area should be tightly pressed against a piece of wood in order to repay the pulse beats and avoid excessive bending of the metal recovered.
If the dent located on the bilayer portion of body panel, or access to the latest reverse side it is impossible for any other reason, it is necessary to change the method. Nasverlite in the most highly deformed areas dents several small holes, then screw them in the long screws, leaving the head protruding above the surface of the latter metal. Now proceed to the metal stretching, grasping screw heads self-locking pliers.
In the next processing step to be completely clean paint from the damaged area and surrounding it at a width of approximately 3 cm panel surface. This work is best done with a wire or an electric drill to the grinding cup. No less effectively stripping the paint can be done manually with sandpaper. The final stage of preparing the surface for sealing of a coarsening of naked metal dents by scratching it with a screwdriver or a fragment of a file or drill small holes. The surface roughness improves adhesion thereto putty paste. Then you can begin to spackling and painting of the treated area.
Repair of the rusted holes and holes
With the grinding or wire electric drill to remove the nozzle from the damaged area and the section width of about 3 cm around the paint. Not less effective work can be done manually with sandpaper. Clean the surface of the paint, we can estimate the extent of damage to metal corrosion and determine the question of the appropriateness of the repair panel (perhaps wiser to replace it entirely, if at all possible). New body panels can often be purchased far for so much money, as it seems - just spend a couple of days circling the city and automobile disassembly dump.
Remove the damaged panel, all the elements of body decoration, except for those that can serve as a reference in the restoration of the original shape of the damaged area (for example, lining block headlights, etc.). Tin snips or using the saw blade, remove any loose loose, loose and hopelessly corroded pieces of metal. A hammer bend aperture edges inside to form a recess to accommodate a putty material.
A wire brush to remove the damaged section of powdered rust. If there is access to the back side panel, treat it around the damaged area corrosion inhibitor.
Before proceeding with spackling should drown out the hole. This is usually done by gluing or screwing to the back side of the panel in the damaged area of her piece of tin, fine wire mesh or aluminum foil. Securely locking hole, you can proceed to the subsequent sealing of the panel and its coloring.
The best material for the mute large holes are fiberglass or fine-meshed plastic grid. After cutting an appropriately sized piece of material, get it in the hole and fasten the lap with the rear side of the lumps of putty paste.
To seal the narrow holes best aluminum foil comes in the form of adhesive tape. It is enough to remove the protective film and glue the foil on the back side body panels to damp hole. To strengthen the foil may be glued in several layers.
Spackling and painting
Currently, the chemical industry offers customers a wide range of attention of various car body fillers. However, for this type of work is best offered in a kit with a set of body panels two-repair putty with hardener paste in a tube. To achieve smoothness and accuracy form toothpaste plastered surface must be placed a flexible rubber or nylon applicator.
Strictly following the manufacturers instructions (violation of them can result in incomplete solidification putty), mix a little bit of putty on a clean wooden board or a sheet of cardboard. Try to carefully spend hardener.
Applicator, apply the prepared mixture on the treated (See above.) The surface area of the damaged body panels. For proper circuit output surface of each stroke applicator must pass through the entire length of the restored area. Once the shape of the restored area close to the original panel, immediately stop applying putty, as it is, freezing, begins Podlipaev to the applicator, forming lumps and leaving a furrow on the treated surface. Continue to apply the plaster layer after layer at intervals of about 20 minutes to as long as the level of the surface area restored slightly exalted above the surrounding metal of the panel intact.
By hardening paste, excess putty can be removed with a scraper or a file. Then begins the stage of sanding and polishing. Best of all this work is done using waterproof sandpaper grit with a uniform and stable adhesion of the abrasive (preferably imported). Root be coarse grinding paper number 40, according to the progressive lowering granularity number 400. In order to achieve an adequate surface flatness sanding paper must be wrapped around the bar of solid rubber, wood or foam (for convenience, the paper may be stuck on the bar). During the surface treatment of paper should regularly and frequently be wetted with water. The described technology allows for absolute smoothness of the surface restored at the final stage of grinding.
On completion of grinding the treated area should be surrounded by a ring of pure naked metal ending gradually tapering off the edge of the undamaged paintwork. Rinse the treated area with clean water panels, flush with it all formed during polishing abrasive, then carefully dry the surface.
Because aerosol spray the treated surface, covering it with a thin layer of light-colored primer that will help identify all the admitted mistakes in the process of polishing. Then the detected defects are eliminated by re zashpaklevyvaniya. Repeat step polishing. Continue to operate in the same vein until until you get the desired shape and smoothness of the restored section of the panel. Finally, do not forget to rinse the board with clean water and dry it.
Now you can move on to the stain. Working with the spray gun must be carried out in still air in a dry and dust-free room. If circumstances force to carry out painting outdoors, you should seriously consider the choice of suitable weather conditions. When working indoors, nail dust, sprinkling the floor with water. If a painting is made of a separate section of the body, cover the surrounding undamaged panel old newspapers, fixing them with adhesive paper tape. Such trim elements as decorative chrome strips, door handles, lined block headlights, etc., at the stage of staining is best to remove from the body panel.
When using the supplied in the form of aerosol spray paint thoroughly shake and then spray the surface of the test, practicing painting techniques. Cover prepared for painting the surface with a thick layer of primer. The thickness of the coating to be achieved due to multiple thin layers of paint. Sparing no water to prepare abrade the surface with fine sandpaper ?�� 400. Before applying the decorative paint give the primer dry completely.
Begin thin layers applied to the primed surface of the decorative paint. Staining starts from the center portion of the recovered, making hand with aerosol spray / kraskopultom circular motion, in a spiral extending their range and without stopping before until all the prepared area will not overlap with three to five centimeters coated with a layer of fresh paint. After 10 ÷ 15 minutes (preferably not later, so as not to damage the edge of the paint starts to dry) after the last coat unstick covering the surrounding body panels masking tape and remove the paper.
Final curing ink occurs after about two weeks, and then to smooth the transition from the old to the fresh paint, rub the surface of the recovered fine polishing paste. Finally, the treated panel wax.
Restoration of plastic components
Repair cracked plastic components should be entrusted to specialists. The technology put to use boron-machines for protachivaniya groove along the crack, which then fit the plastic rod of the same type of plastic, which is itself the repaired item. Further cracked panel halves are welded to each other using the special dryer. The excess plastic is removed by polishing.
Less serious damage can be repaired in-house mechanics amateur by filling the defect 2-component epoxy resin (similar to the technology used in the shpaklevanii damaged sections of metal body panels).
When replacing damaged plastic components should take care about the selection of a suitable color replaceable panels. For coloring made from plastic parts, use special paints and primers - ask in shops of automobile accessories and strictly follow the manufacturer's instructions.
