1. Strictly following the manufacturer's instructions (violation of them can lead to improper hardening of the putty mass), knead a small amount of putty on a clean wooden or cardboard surface (use hardener carefully).
2. Apply the putty with the applicator to the suitably prepared (see above) the surface of the damaged area of the body panel.
3. To achieve the desired surface contour and putty level, each stroke of the applicator should go through the entire surface to be repaired.
4. As soon as the contour of the putty surface is close to the original, immediately stop applying the putty, as it, when cured, will begin to stick to the applicator, forming lumps and leaving scuff marks on the treated surface.
5. Continue applying coats of paste at intervals of approximately 20 minutes until the level of the putty surface is slightly above the surrounding metal of the panel.
6. After the putty has hardened, the excess can be removed with a file.
7. Next, the stage of sanding and grinding the puttied surface begins. Imported waterproof sandpaper is best suited for this purpose (since it maintains a uniform grain size of the abrasive and its good adhesion to the base). You should start with coarse-grained paper No. 180 and, progressively reducing the graininess, you can finish with No. 600. In order to achieve adequate flatness of the work surface, the paper must first be wrapped around a block of dense rubber (wood or foam) or stick on it. During processing, the paper must be regularly and frequently wetted with water. This technology allows you to achieve absolute smoothness and evenness of the treated surface at the final stage.
8. At this point, the treated damaged surface should be surrounded by a ring of clean, bare metal, ending in a gradually fading edge of good paint. Rinse the treated surface with clean water, washing off all the abrasive formed during grinding.
9. From an aerosol can, spray the treated surface with a thin layer of a light primer. This will reveal all the defects made during grinding, which can be eliminated by covering them with a layer of fresh putty.
10. Repeat the sanding and sanding step.
11. Repeat alternating puttying, treatment and priming of the surface until a satisfactory result is obtained.
12. When finished, rinse the treated surface with water and dry it.
The surface is now ready for painting. Aerosol painting of a car should be carried out in still, dry, warm, and dust-free air. The conditions of a volumetric closed and heated room most fully meet these requirements. If circumstances force you to paint the body outdoors, you should be very serious about choosing the right weather conditions.
1. When working indoors, beat down the dust by spraying the floor with water.
2. If only a single body panel of the vehicle is being painted, cover the undamaged panels surrounding it.
3. This precaution will minimize the effect of slight differences in tones between old and fresh paint. Finishing elements such as chrome decorative strips, door handles, etc. should also be covered (better to take it off).
4. To protect non-paintable surfaces, use adhesive tape and old newspapers, which should be applied in several layers.
5. Shake the can thoroughly before using the spray, then spray paint on a test surface while practicing the staining technique.
6. Cover the surface prepared for painting with a thick layer of primer. The thickness is achieved by repeatedly applying the primer in thin layers.
7. Sparing no water, with moisture-resistant sandpaper No. 600, process the primed surface, achieving its absolute smoothness.
8. Allow the primer to dry completely before proceeding with the final painting.
9. Apply a layer of decorative paint, again achieving thickness by applying it repeatedly.
10. Start painting from the center of the area to be repaired, making circular movements with a spray can, expanding their radius in a spiral until the entire damaged area is covered, plus another ring of the surrounding good about five centimeters wide.
11. After 10-15 minutes (better not later, so as not to damage the edge of the fresh paint starting to harden) after applying the last coat of paint, peel off the newspapers and adhesive tape that covered the surrounding body panels.
12. The paint cures completely within about two weeks, after which, to smooth out the transition of fresh paint, treat the restored surface with a very fine sanding paste.
12. Finally, apply a layer of wax to the panel.
