Align the putty on the damaged area of the body so as to give it the desired shape and smoothness.
As soon as you have achieved approximately the desired contour, stop smoothing the putty with a spatula, as if it is smoothed for too long, it will harden, stick to the spatula and roll off, as a result of which the surface will be damaged.
Apply a subsequent, thinner layer of putty only after the previous layer has dried and so on until the level of putty begins to slightly protrude above the treated area.
After the putty has hardened, remove its excess with a metal scraper or file.
Further processing is carried out using coarse-grained sandpaper at the first stage, then fine-grained sandpaper. Sandpaper should be placed on a flat wooden block, otherwise it will not be possible to achieve a smooth surface.
At the final stage of grinding, waterproof sandpaper should be periodically moistened with water. This will give the treated puttied surface a special smoothness.
The puttied dent should be surrounded around the perimeter by a layer of clean metal. To remove dust and grease, rinse the treated area with water and wipe with a degreaser.
Spray the area with a thin layer of light primer. This will help to identify all defects in the putty made during processing. Align them with a new layer of putty and re-sand the surface.
After that, the repair area is ready for the final painting.
Aerosol paint application should be carried out in a warm, dry, windless and dust-free atmosphere.
When painting indoors, dampen the work area floor with water to prevent dust from entering the air. When painting only one panel, the remaining parts of the body must be covered from paint on them with a newspaper attached with adhesive tape.
Before applying the primer, mix it thoroughly, apply it on a test surface and ensure that it lies evenly. Apply a thick layer of primer, for which apply several thin layers.
Sand the primed surface with waterproof sandpaper. At the same time, do not forget to spray the area to be sanded with water and periodically moisten the sandpaper in water.
Dry the area to be treated before further painting.
Apply a coat of paint with a spray gun. The required thickness of the paint layer is achieved by applying several thin layers.
Start painting from the center of the surface to be treated and move towards the edges in a reciprocating motion until the entire surface to be painted and the area about 20 mm around it has been painted.
Remove the protective film and newspapers 10-15 minutes after applying the last coat of paint.
Allow the fresh paint to cure for at least two weeks, then use a paint refresher or fine abrasive polishing paste to smooth the edges of the painted area to the level of the old paint.
Polish the surface.
