Polishing of car windows from scratching with your own hands

The body of the car is constantly exposed to wear. And besides the paint coating, glass suffers. In particular, frontal. Various stones that fly into it from under the wheels of the cars ahead can cause chipping and scratches. Also, similar defects are formed on the rear lade, if it is equipped with a windshield wiper. Replacing the glass with a new one is a very effective but very expensive solution. Especially if the frontal whole, and the scratch is insignificant. So, let's look at how the windshield is polished from scratches, and what you need for that.

Causes of defects

The main cause of scratches is road dust. It settles on the rubber band of the janitor. When the wiper is turned on, it starts rubbing against the glass and working as an abrasive. Also, the cause of scratches can be a worn janitor. The elastic often does not withstand large temperature fluctuations and loses its elasticity after 1-2 years.

To avoid repeated scratches after polishing the auto glass, it is recommended to remove the accumulated dirt on the rubber bands, change the wipers in time and keep the frontal itself clean (do not be lazy to wash it by hand). 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:

• Painting Scotch.
• Liquid for cleaning glass.
• Soft rags.
• Polishing wheel with Velcro and grinding machine.
• Color marker.
• Special powder for polishing.

Pay attention to the characteristics of the grinder. This can 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 polishing the car's windows from scratches? Before starting work, clean the surface thoroughly of dirt and degrease it. It is not necessary to use antisilicone or white spirit. It is enough to use the liquid for cleaning glass, which is sold in any supermarket in the form of a spray. So, dry the glass and circle the marker from the inside with all visible defects. Why should this be done? The fact is that when polishing it is very difficult to notice the edges of the scratch. If the surface is treated in the wrong place, a lens may be formed. Also, if the scratch is near the edge of the seals or body parts, glue them with paint tape. It is important to prevent the abrasive powder from getting onto the paintwork. Otherwise, there will be dim matte spots.

Now we take in hands a polishing powder and we breed it with water. All proportions will be indicated in the instructions to the tool. As a result, we will get a composition that is close in consistency to the cream.

Getting Started

So, we put this cream on the grinding wheel. Further, not including the machine, we carry out a small strip along the perimeter of the scratch. So part of the abrasive cream will remain on the damaged area. After that, the auto glass is polished. The nozzle is moved by smooth translational movements.

Note that the glass can overheat even at low revs. Therefore, it is not recommended to process one section 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 the spray.

After the traces of polishing have disappeared on the glass, we turn off the sanding machine and look at the quality of the work. It's better to check it in a well-lit room. If polishing the car's windows from scratches did not save much, repeat the procedure again. Sometimes, for an effective result, 3-5 repetitions are required.

In order to avoid the effect of "lenses", in passing process nearby areas. Thus, we get the most flat and transparent surface, without matte spots and strong transitions. From the scratch itself, you can retreat by 7-10 centimeters to the left or right side.

The final stage

At the end of the work, the glass should be washed again. But you do not need to do this right away - wait a couple of minutes until the heated surface cools down. Then you can start the routine operation. It is advisable to change the rubber bands of the janitors after the work done.

Price in service

How much does professional glass polishing cost? The price of such services starts from three thousand rubles. The cost is indicated per one square meter. Therefore, it makes sense to polish the car glass from scratching with your own hands.

The main costs will be on the grinder and the nozzles themselves. But, as practice shows, all expenses pay off for one application.

Conclusion

So, we examined what is polishing the car's glasses from scratches and how it is made. This is a great way to restore the old glass to the factory look without replacement. The procedure is very painstaking, but less costly than replacing the frontal one with a new one.
