Do-it-yourself car polishingJuly 5, 2010
During the operation, our four-wheel friends gradually lose their glossy shine and brightness of paints under the influence of various external factors, so polishing your car with your own hands is absolutely necessary for your car to return to its former shine. In addition, the polishing process eliminates the smallest defects and microcracks, which can lead to corrosion.
Polishing cars are divided into two types - protective and abrasive. The first polishing is carried out using various pastes that protect the car body from the effects of external factors, forming a protective film on the surface of the car. Polishing pastes are wax-based or Teflon-based, but they all wash out over time.
Longer effect gives abrasive polishing. It is carried out in several stages - first, remove the top layer of paint with the help of abrasive sandpaper, then polish the surface with a special abrasive paste, and then, if necessary, modify the result and eliminate errors.
We polish the car
- Prepared materials and tools - grinding skin with grit p2000 and p2500, grinding block, degreaser and spray for water.
As an example, the car was taken with a clearly visible scratch. It was installed indoors without drafts (so that dust did not settle on the surface) and all plastic parts were sealed with masking tape.
- Work began with the right wing - degreased it and started to eliminate defects by grinding scratches or scratches with sandpaper or bar until a uniform matte surface was achieved. The surface was periodically moistened with water from a spray bottle so that the abrasive cloth becomes less clogged. Then they sanded the remaining surface of the wing so that the place for removing scratches after polishing was not highlighted by a strong gloss. It should be remembered that the skin should be moved along the surface in one direction, and after passing through the entire part, the direction of polishing should be changed. If a large part is polished, for example, the hood, then it should be divided into four parts and deal alternately with each one, bringing it to an ideal state.
- For the next stage - polishing applied a polishing machine and a special paste. It was applied not to the surface area and slightly moistened with an atomizer; you can also moisten the polishing pad. Then they set the minimum speed on a typewriter and rubbed the paste on the surface of the wing. After that, the speed was increased to 1500 and, smoothly moving the polisher in a horizontal direction, began the polishing process.
If the paste dries, then it needs to be re-slightly wetted with water. As for the polishing washer, then two types of washers are sufficient for high-quality polishing - hard (white) and for finishing polishing (black). For polishing light shades, I usually use a hard washer, and for dark colors, both types of polishing washers.
During the polishing process, it is also necessary to monitor the temperature of the polished part so that it does not overheat.
