One of the most practical means of protecting your machine body from aging is polishing.
Polishing removes pores and microscopic cracks that accumulate dust, dirt and chemicals that destroy your car ‘s paint coating. And it ‘s just nice to look at a polished car!
Polishing is of two types: abrasive (or reducing) and protective.
If your car has large body scratches, you should perform abrasive polishing to eliminate them.
Protective polishing is used for short-term prevention of external factors on the paint coating of your machine body.
It is worth taking into account – overreaction with polishing of the body will bring him only harm. During polishing it is never worth:
- Perform polishing on wind or in dusty place;
- Do not place the car under direct sunlight. The body of the car must not be heated;
- Do not polish the car more often than once every 1-2 months.
Polishing pastes are liquid and gel-like (viscous). Both waves are suitable for body polishing, viscous polishes are a little better at handling vertical surfaces.
It should be noted that the durability of the protective coating after polishing depends on the composition of the polishing mixture. For example, the polymer composition will be held on the body for six months, but the wax or silicone polyrol will last 2-3 months. But polymer polyrol is difficult to apply – it takes a lot of time and special equipment.
We prepare the car for polishing
- Carefully and several times wash the car with special shampoos;
- We clean resin, bitumen, anticore and other indelible particles from the body;
- We glue with malar scotch everything that does not require polishing (rubber, plastic parts, etc.);
- If the body is hot, we let it cool down.
Choose a place to work
The place where you will polish the car must meet the following criteria:
- Have good ventilation;
- The inside temperature must be within 19-25 degrees;
- The working area should be very well lit. Ideally have lights located around the car;
- As mentioned above, the vehicle must not be under direct sunlight.
Start polishing process
If you do protective polishing, you can do without equipment. You will need a clean dry cloth, on which you will apply a polyroll, and circular movements will spread it on the body. A thick layer should not cover the body – the surface will simply cloud, and it will not be easy to correct this defect. Also do not soak immediately to cover large areas of the body. Start with a small plot. After application of the polyrole, wait a little until a whitewash film is formed at the treated sites. Then you ‘ll need a soft dry cloth to which you ‘ll polish the treated areas. To get the desired effect, it will be necessary to walk on white film about twenty times circular movements.
Polishing the body with hands is a labour-intensive process. But with perseverance and free time, you can get the most excellent result. The use of a special polishing machine reduces the time for polishing by several times.
In case of reducing (abrasive) polishing time will take 2-3 times more. The whole thing is that at the initial stage the body needs to be cleaned of chips, scratches and abrasions. An abrasive polishing composition should be used for this purpose. After its application it is necessary to treat problem areas with a machine (it is possible, of course, and manually, but it is very time-consuming). The polishing machine should not be pressed hard against the body, as in addition to the lacquer there is a great risk of removing the paint and exposing the metal of the body. Which means you ‘ll need painting instead of polishing.
After removal of abrasions and scratches it is necessary to apply on the body of the car already fine-abrasive paste for polishing, which will remove “turbidity,” small scratches and cracks. If you use a grinding machine, you will need a finishing wheel for the second polishing stage (a rough wheel for the first polishing stage).
After these two steps, we proceed with the protective polishing. We do everything as before, but we use another composition of polishing mixture (non-abrasive).
- If you have no experience, start polishing from small areas. If there are old body parts in the garage, practice on them;
- When polishing with a machine, do not skew the wheel to the body plane. The pressure on the body shall be uniform in all areas;
- Machine polishing of edges, corners and ribs requires special attention, as they are most susceptible to machine damage;
- Plastic and chrome-plated parts can be coated with cloudy film after the polyls hit them. Therefore it is better to seal them with small scotch;
- Start from the roof, gradually dropping down;
- The machine after painting can be polished not earlier than in three months, otherwise the paint coating will spread and become soft;
- Do not forget to wet the polishing sponge (but to wash it better) with warm water during polishing. For example, the hood and two doors were polished – the sponge was washed. Etc.;
- Constantly monitor the temperature of the surface you are polishing. Polishing the hot areas of the body will produce a low quality result;
- The ideal option is double protective polishing. After it is carried out, the effect will be simply surprising;
- The time required for polishing of one body is 7-8 hours.
Good luck to you, in this difficult but pleasant event!
