The legendary "nine" of the Volga Automobile Plant does not lose its popularity among the youth. This is especially noticeable in the outback, where such machines become the object of technical creativity of novice masters. But as always, they lack knowledge and experience. This article highlights several important points in painting the VAZ-2109.
A bit of technology
Most of the bodies of the "nine" was painted according to the "paint + varnish" system. This technology is needed to obtain a coating with a "metallic" or "pearl" effect. During the repair process, it is important to take into account the fact that the only function of the paint in this system is to create a decorative layer, and the function of protecting the body from corrosion is performed by the primer system and clear varnish.
Paints like "metallic" and "mother-of-pearl" are almost transparent, for this reason they poorly paint over light VAZ primer. Therefore, on many cars of the Zhiguli family, you can notice a factory defect, socalled "neprokras". All this information will be required to answer the question of how much paint is needed to paint the VAZ-2109.
Years of practice shows that with a competent organization of the process for painting the outer part of the "nine" body with door openings and the inside of the doors themselves, two liters of paint and two liters of varnish can be enough. To achieve this result, you need to know a few technological "secrets".
Creating an underlay that saves ink
In order to apply paint in no more than two layers, the machine must be primed with a composition of the appropriate brightness. The term "brightness" implies a rating in terms of lighter or darker from white to black. For example, if your car is white, buy white primer, if black, then black. More difficult with metallic and mother-of-pearl. In these cases, you will have to mix black with white in certain proportions.
To understand how bright the ground should be, you need to look at the car not at a right angle, but from the side. Consider, for example, the popular silver metallic "Snow Queen". When viewing at an angle of 90 degrees to the surface, the color will be very bright and aluminum powder will be clearly visible under the varnish. If we shift the viewing angle along the car, the brightness will gradually decrease, and we will see a neutral gray color. This is how your soil should be.
And it does not matter at all what shade of metallic or mother-of-pearl - yellow, red orgreen, it will just change the brightness of the gray ground. In any case, it should be such that it can be easily painted over with two coats of paint.
Economic Varnish Choice
Painting the VAZ-2109 can become quite budget-friendly if you can also save on varnish, so its choice should be taken seriously. Of all the variety of options on the market, the most economical will be a varnish with a high solids residue. It is applied not in two, but in one and a half layers, so two cans are enough for a small body of the "nine". Such varnish is indicated by the presence of Latin letters HS on the package.
Advice for those who want to paint the VAZ-2109 with their own hands
If there is through corrosion on the body of the "nine", it is not necessary to use welding for repair. Fiberglass and polyester resin will do the job just as well. All details are shown in the video.
To make it easier to remove rust around the rubber glass seals, bend the edge of the rubber band with a flat screwdriver, insert a piece of a round electrical cable with a diameter of 4-5 millimeters under it.
Significantly speed up the preparation for painting the VAZ-2109 can be a vibration grinder with an electric or pneumatic drive. The diameter of the plate should be 150 millimeters, and the stroke of the eccentric should be at least 5 millimeters. Machines with a smaller stroke are designed for furniture production and are characterized by low productivity.
If you buy a soft backing and abrasive wheels of P 400 gradation for the machine, then frommanual grinding should be completely abandoned, since paint can already be applied to the ground treated with such an abrasive.
A large part of the VAZ-2109 bodies is painted according to the so-called single-layer system. Unlike the two-layer (paint + varnish) system discussed above, it does not use varnish. According to this scheme, all cars in the world were painted until the 50s of the XX century, until metallic paint was invented in the USA.
Naturally, painting a VAZ-2109 car using a single-layer system is much easier and about 60% cheaper.
