We remove chips and scratches on the car body with our own hands
Vehicle owners sometimes have to deal with the concepts of chips and scratches.
Any defect, regardless of its size and severity of damage, must be repaired. It's just that many drivers decide that small scratches do not interfere with the use of the car for its intended purpose, which means that you should not pay special attention to them.
But you should not ignore them, because if you look at the issue from the other side, you will quickly realize the need to solve this problem.
The car loses its remarkable appearance, besides, chips are a great excuse for the formation of rust. By applying repair work, you can prevent corrosion of the case.
Modern technologies, thought out to the smallest detail, therefore allow you to achieve an amazing effect, after eliminating all the damage, your vehicle will be difficult to distinguish from a new one.
Innovative designs are specifically designed to address this issue, such as the scratch removal pencil, which does the job perfectly.
So external defects are painlessly eliminated, and pencils are resistant to the influence of the external environment - sunlight, moisture, changes in temperature. Traditional body repair will also help in this cases.
The choice of a way to solve this problem directly depends on the complexity of the breakdown, the capabilities and desires of the car owner.
Reasons for the appearance of chips on the car body
It is necessary to treat your vehicle with care, and listen to changes in behavior, then it will be possible to prevent many breakdowns. Including avoid various damage to the paintwork.
As a rule, mechanical influences are the main cause of the appearance of chips. During careless parking, or during an accident, serious damage to the coating of the car can be caused.
Not only the appearance is violated, but serious damage is also caused, because the development of corrosive processes is not excluded. If the problem is not solved, it gets worse over the years, the metal loses its strength.
If you decide to put the car up for sale, then you will notice how the cost decreases due to such defects, the sale process slows down.
Even the most careful drivers will not be able to avoid such a problem. The most common place of damage is the hood or bumper.
The road surface is not perfect and a scratch can be formed even from a pebble flying on the side, dry branches. Statistics show that more than half of the cars have various degrees of deformation from scratches to cracks.
There is an opinion among drivers that the damaged area will have to be dismantled, because of this, the work process is delayed, and a car is literally always needed.
Therefore, many people postpone repairs because of this, because of which, over the years, corrosion gets a good opportunity to develop.
In fact, repairs sometimes take 4 hours, which is worth spending to transform your car.
Other occurrences of defects on the coating:
- Incorrect definition of paintwork material;
- Poor-quality degreasing - the paint will not be able to lie flat if there is contamination;
- To avoid creating irregularities, it is worth using a special machine for grinding, otherwise defects may occur;
- Due to poor-quality puttying - poor material, violation of application technology;
- Violation of proportions in the process of mixing materials;
- Use of faulty painting equipment - spray gun or compressor. Due to uneven application, defects may occur.
Equipment for repairing scratches and chips
In order to eliminate defects on the paintwork without problems, you should listen to a number of rules:
- Review the literature on safety in body repair. Study the technical recommendations on the preparation of the surface for work, check the good condition of the equipment, the choice of materials.
- Do not save on materials and follow the instructions for their use and mixing proportions;
- To avoid mismatching the chemical constituents of materials, purchase them from the same manufacturer;
- Do not rush - this is the basic rule, due to the violation of which the main complications arise during body repair.
Before proceeding to work, it is necessary to determine its scope. The use of modern equipment will save a significant amount of time.
Before using the equipment, read the manual, you can learn about the new functionality.
Due to improper storage, the tool may fail, so it is worth checking its condition before carrying out all work.
Polishing machines, spot welding tools and other equipment are all needed to paint over chips and scratches. Before work, decide how seriously the body is damaged.
If the scratch is superficial - a violation of the top coat of paint, then the repair process will take a little time.
Would need cosmetic pencil, however, such coverage will have to be updated at certain intervals.
But a wider scratch is better to tint with the selected color. In order not to go beyond, it is necessary to highlight the scratch around the perimeter with a patch. It is recommended to apply two thin coats.
Another way to eliminate small scratches is to use a polishing machine. Polishing the top layer will get rid of the problem without unnecessary interventions, changes.
If the soil layer is damaged, then serious intervention in the problem may be required. Do not delay the repair in this case. You will have to apply a layer of primer, which will allow the paint to hold out better. After the primer dries, apply the paint in several layers.
If yellowness appears in the scratched place, you need to get rid of it - treat the place with white spirit and apply a special primer that has special anti-corrosion additives.
The selection of paint should not take much time and effort, because the code of the color you need is indicated on the trunk in the plate.
Turning to the master, you will receive a more accurate analysis and selection of paint according to the computer program developed for this.
It will save money, and special paint kits for chips will help solve the problem of painting defects.
Knowing the scope of work, select the number of vials.
If the scratches are on painted plastic bumpers, then they can be touched up using a repair bottle.
Sometimes such a shade as “metallic” is not easy to bring into proper form, because it can turn out to be brighter and shine, to eliminate such moments, use acrylic varnish from a repair can.
Chips have a greater depth than scratches, but the procedure for their elimination is almost the same. But in this case, an ordinary wax pencil will not be enough, then it is better to take paint and eliminate inappropriate moments.
If you do not have much time, but it is necessary to resolve the issue, in winter it is better to cover the chips with Movil. Rust will not go with him in defective places, the problem will be “mothballed” until better times.
Then it is washed off with diesel fuel or white spirit, only then can we begin to repair the damage.
Chip removal work
Work to eliminate defects is carried out in stages, everything is done measuredly and without haste.
1. Examine the places that have been subject to deformation, they must be cleaned. For this, detergents like white spirit are used.
2. Decide on the type of coverage. There are not so many options on the auto market: acrylic, which we are used to seeing on domestic cars, acrylic for varnish, and also metallic.
If you can't determine what coverage you have, then use one experiment. Use polishing paste and wipe off a small area with a cloth.
If there is dirt on the fabric, then varnish has been applied to the coating. If there is a little paint on the rag, then most likely the varnish was not used in the coating. So it will be easier to decide what is more suitable for you to eliminate violations of the coating - acrylic or synthetic paint.
3. If rust elements have already begun to appear at the site of the defect, then it is worth cleaning it. In this case, it is better to use a file, a knife, chemicals.
4. In order for paint and varnish to better adhere to the surface, it is recommended to use sanding paper.
5. After wiping off the rust, coat with a primer and preferably a two-component one. A couple of drops is enough in this case. The primer is applied with a brush or a match, depending on the area of the treated surface.
The procedure is repeated once again with a frequency of a quarter of an hour. Speed up the drying of the material by using a hair dryer, only when the primer is completely dry, you can treat the chips with paint.
6. Stir the paint before applying it. If the surface is acrylic, then the procedure will not take much time; it is necessary to apply a thin layer of paint every 15 minutes.
Since shrinkage occurs, there will be more than one layer. Paint is worn until a small tubercle is formed.
7. Grinding will help to level the emerging tubercle. You need to level it with the surface of the car. To protect the paint next to the work surface, you need to apply a small layer of nitro putty.
Grinding is carried out only after drying of the applied materials. Prepare yourself a piece of sandpaper for work, where the grain size is R1500.
In work, use water to rinse the sandpaper. Watch the bump as it disappears, and don't apply too much pressure.
When the tubercle begins to noticeably decrease, then it is worth using a different size of emery - R2000. at the end of the work, you will already have a smooth matte surface. To get the long-awaited result, you can immediately start polishing.
Following the elementary rules, you can get rid of defects on your car. But there is a possibility that doing this for the first time, you can do something.
Let's consider what kind of troubles there are after the surface treatment has been carried out.
car body protection
The problem of protecting the painted surface of the body from chips and scratches is very relevant. After all, everyone wants to preserve the original appearance of the car, and small details on the road surface interfere with this.
They can even spoil the painting at the sink, where, if all the rules are violated, it is easy to wash it off simply along with the dirt. A lot of remedies have been developed, but not all of them are effective.
Many people believe that polishing is enough to protect the car from scratches, but this is not the case. The coating will wash off faster than the paint itself.
However, protection is still there, that's just from the ingress of dirt particles. If you still think that polishing is an excellent protection against mechanical influences, even from a stone hit, then you are wrong.
The so-called "muzzle" can also be attributed to ineffective means of protection. Over time, sand and dust get under it, which periodically eats away small pits.
Plastic deflectors also cause harm over time for the same reasons, although initially the device performs its function.
The above means do not have the desired result, but more effective means are still on the market to ensure body protection.
One of them "liquid case", which has a certain composition.
After applying it to the body, according to the rules specified by the manufacturer, a long-awaited protective coating appears on the surface, which looks like a film.
If you do not observe all the technological aspects of application, then it will not be able to fulfill its purpose.
Once you've driven through bad sections of the road and it's time to remove the protective layer, you can easily remove this layer without damage or marks on the surface.
Another reliable means of protecting paint on a car from road gravel in this case is an armor film. Just be prepared to pay much more for it than in previous cases.
The film is transparent, so it can not be seen on the car. Often, experts give recommendations about this particular protection option, and some manufacturers still use it at the factory.
Such a lenka will last for several years. The service life depends directly on the operating conditions of the car, driving style, habitual speed.
Over time, you will be able to remove it, but you need to do this carefully, it is better to contact specialists.
The most common car body protection options have been presented in front of you. You can evaluate all their advantages and disadvantages yourself.
Defects from violation of painting technology
So that the painting work does not turn into a surprise for everyone, it is worth painting in accordance with the existing rules.
As soon as you try to move away from the principles of painting and somewhere save time, money, then you will surely stumble upon post-repair defects. Such errors are then corrected more difficult than removing scratches.
The main problems that may arise:
1. Uneven splashing of paint. Spots of soil can appear through the soil, form stripes.
2. Matte coating. If the surface does not turn into gloss in any way, then the procedure took place at high humidity. Another mistake that could lead to this is the presence of an excess hardener particle.
3. The presence of streaks and leaks, is explained by the liquid consistency of the paint or by applying a new layer to a layer that has not yet dried.
Assessing all the complexity of the work, you perfectly understand how difficult the repair of chips is still a difficult task.
If you do not have basic information about this, then you should not take on this procedure, but if puttying, priming, applying paint are familiar processes for you, then you will definitely cope with the task.
A professional painter can easily cope with the elimination of defects on the body coating, because he has many repetitions of the procedure and experience behind him.
It’s just that you need to prepare for the process - by checking the serviceability of the equipment, consumables and simply focus on the procedure itself.
If you are not confident in your abilities, contact the workshop, where you will definitely be provided with the long-awaited result, the performance of quality work is guaranteed.
