Most car manufacturers of modern cars use polycarbonate – special plastics as a diffuser of light headlights. Compared to glass headlights, such an optics has significant advantages, it is cheaper and it is easier to give intricate forms. But plastic headlights have one significant drawback, during operation from the effects of sand and stones, many microscopic scratches are formed on the surface. Dirt, falling into such damage, causes clouding of glass and, as a result, reduces its throughput, and light scattering occurs incorrectly.Replacing the glass of the headlight will not be a big problem if it is collapsible, but most modern cars use block facts, the cost of which can reach several hundred dollars, which not everyone can pay out. You can get rid of the clouding of optics with simple polishing the head of the headlights with your own hands. Repair of plastic headlights can be divided into polishing small scratches and eliminating chips and deep bulletin. You will not need so many material and tools to conduct polishing, you only need time and some dexterity in the repair work. If desired, such work can be carried out in a car service.
If you still decide to polish the headlights with your own hands, then you will need masking tape, abrasive materials (sandpaper) of various grainness, polishing pasta for thin and rough polishing, electric drill (electric shurovyrt) with a polishing or grinding, locksmith tool, masking tape, masking tape rags, polishing fabric (felt) capacity with water. In the absence of a mechanized tool, you can carry out manually, but at the same time, the time of work will increase significantly. It is better to carry out work with the headlight removed, but if it is laborious, then during work it is necessary to glue the adjacent places into several layers with a painting tape.
Politing headlights.
We thoroughly wash the headlight from dirt and fat, for this you can use household chemical drugs (washing products or washing powder) and examine the optics for damage, remember the largest scratches. Using a grain of 1500 and a grinding device, we begin to polish the glass of the headlight. Work should not be carried out at high speeds of the power tool and pressed hard on the processed surface, the glass should not heat up. When heated, the plastic may be clouded, and this is almost impossible to eliminate. When carrying out work, it is necessary to periodically wash the grinding waste from the headlights. As a result, the glass of the headlight should become uniformly matte.
Next, we move on to polishing the headlights with sand materials with smaller grain, not forgetting to wash off the remnants of the previous polishing. Each subsequent polishing must completely remove traces of the previous. The work should be completed with sandpaper with a granularity of 2500-3000, while the headlight becomes a dull spraying, smooth to the touch, and the water should slide, as if the glass has become fat. At the end of polishing with sandpaper, we move on to polishing with special pastes. It is better to carry out work in three stages: first with a paste with large grain then with medium and small. Rinse the glass thoroughly and wipe it dry. We apply polishing paste on the glass and distribute it over the entire surface and polish it using a power tool or manually to complete transparency.
Removal of deep scratches and chips
The performance of work is the same as when polishing, only you need to start with the sandpaper of large grain (400-600 for waterproof sandpaper). The gradation of the sandpaper used should be 200-300 units, an approximate sequence of 600-900-1200, etc.D. reaching to 2500-3000. The smaller the gradation step, the better the result. When conducting this operation, it should be remembered that it is very difficult to remove especially deep scratches and the plastic is very refined, so when repairing, they should be achieved by maximum invisibility. It is better to carry out work with a coarse -grained skin manually, since scratches from careless movement with a power tool will have to be removed for a long time.
