The car body is constantly subject to wear.And besides the paintwork, glass also suffers. In particular, frontal. Various stones that fly into it from under the wheels of cars in front, can cause chips and scratches. Also, such defects are formed on the back "Lyad", if it is equipped with a wiper. Replacing the glass with a new one is a very effective, but very expensive solution. Especially if the frontal integer, and a minor scratch. So, let's look at how to polish the windshield from scratches, and what it takes.
Causes of defects
The main cause of scratches is road dust.It settles on the surface of the janitor's gum. When you turn on the wiper, it starts to rub on the glass and works like an abrasive. Also, the cause of scratches can be very worn janitor. Elastic often does not withstand large temperature differences and loses its elasticity after 1-2 years.
To prevent repeated scratches afterpolishing auto glass, it is recommended to remove the accumulated dirt on the elastic bands, in time to change the wipers and keep the windshield clean (do not be lazy to wash it manually). Despite its strength, this surface is very afraid of hard rubber and dirt.
Instruments
So we found a scratch. To remove it, you need to prepare the following set of tools:
- Masking tape
- Glass cleaning fluid.
- Soft rags.
- Velcro polishing wheel and grinder.
- Color marker.
- Special polishing powder.
Pay attention to the characteristics of the grinder.This may be a drill or a Bulgarian with a special nozzle. It is important that its turnover does not exceed one and a half thousand per minute. Otherwise, you can easily overheat the glass.
Preparation
How is car glass polished fromscratching? Before starting work, thoroughly clean the surface from dirt and degrease it. It is not necessary to use antisilicon or white spirit. It is enough to use a glass cleaner that is sold in any supermarket as a spray. So, wipe the glass dry and draw a visible marker on the inside with all visible defects. Why do you need to do this? The fact is that when polishing it is very difficult to notice the edges of the scratch. If the surface is not processed in the wrong place, a lens may form. Also, if the scratch is near the edge of the seals or body parts, paste them with masking tape. It is important to prevent the ingress of abrasive powder on the paintwork. Otherwise, there will be dull dull spots.
Now we take in hands polishing powder and we part it with water. All proportions will be indicated in the instructions to the tool. As a result, we will have a composition similar in consistency to the cream.
Getting Started
So, we put this cream on the grinding wheel.Further, not including the machine, we spend a small strip along the perimeter of the scratch. So part of the abrasive cream will remain in the damaged area. After that, the car itself is polished. The nozzle is moved smoothly forward movements.
Please note that glass may overheat.even at low revs. Therefore, it is not recommended to treat one site for a long time, making great efforts. The polishing process should be extremely accurate. Also make sure that the polish does not dry out. To do this, periodically spray the surface with water from a spray.
После того как на стекле пропали следы полироли, Turn off the sander and see the quality of work. It is better to check it in a well-lit room. If polishing the car windows from scratches did not save much, repeat the procedure again. Sometimes for effective results it takes 3-5 repetitions.
Чтобы избежать эффекта «линзы», попутно process nearby areas. In this way we will get the most even and transparent surface, without matte spots and strong transitions. From the scratch itself, you can retreat 7-10 centimeters to the left or right side.
The final stage
At the end of the work should be re-washed glass.But this should not be done immediately - wait a couple of minutes until the heated surface cools down. Then you can proceed to everyday use. It is advisable after the work done to change the gum wipers with new ones.
Price in service
How much does a professional polished glass cost?The price of such services starts from three thousand rubles. The cost is per square meter. Therefore, it makes sense to polish the car windows from scratches with your own hands.
The main costs will be on the grinder and the nozzles themselves. But, as practice shows, all expenses are paid for in one application.
Conclusion
So, we looked at what constitutespolishing car windows from scratches and how it is made. This is a great way to return to the old glass factory view without replacement. The procedure is very painstaking, but less expensive than replacing a windshield with a new one.
