Assortment of attachments
The most common products for processing automobile bodies are: sponge-like, abrasive with varying degrees of grain, felt, having a soft surface. They are conventionally classified according to the type of production into two types:
- petal (has high productivity and high price);
- surface grinding (made like a rubber disc with an additional coating for processing).
The material for these items is dense foam rubber or felt, which has different diameters. However, kits are sold that consist of several elements that have different purposes and manufacturing complexity.
Making your own nozzles
If there is no suitable option on sale, then for a disk with a high level of rigidity you can make a soft layer of great thickness and place it between Velcro and a plastic base. Using a utility knife, you need to cut off the Velcro where the soft layer will be glued. For the soft layer, a bath sponge is mainly used. It must be remembered that individual elements can shift, breaking the overall symmetry.
You can also use a felt disc, which is used in a polishing machine and machine. First, you should make a pin with a suitable diametrical size and apply a thread on one side. On this side you need to secure the disk, which is surrounded on both sides by a wide nut and a limit washer. This device is not difficult to manufacture and can be used to process various surfaces.
Application nuances
A drill attachment for car polishing can be purchased at any store that sells car products. However, you should choose these devices carefully.
Body elements of new cars are made using modern technologies. An anti-corrosion compound and paint are applied to the metal, which are wear-resistant. They will last approximately 15 years. However, this coating is better preserved if it is properly cared for. The polishing device restores the original shine and removes defects from the surface. Together with a special product, such a product will cost less than services provided in a workshop.
Form
Car polishing attachments are usually made in the form of a cone or a circle. They often come as an addition to polishes, along with polishing belts and sheets. There are many options that are used for both bodywork and jewelry or optics.
Thanks to such elements, the aesthetic and technical characteristics of the car are preserved, since any vehicle will look much better after a thorough washing and polishing.
Body polishing
The polishing process can correct only some defects. If there is corrosion, chips or damage on the body through which the steel frame is visible, then a major repair will be required.
Before starting the polishing process, you should carefully inspect the vehicle to ensure that any imperfections can be eliminated.
Treatment of the body with a special device will give a positive result if:
- slight difference in shades that resulted after partial coloring;
- the presence of roughness, scratches and cloudy stains;
- faded layer of paint;
- the appearance of graininess and streaks of enamel.
You need to know that you can’t overuse polishing, because when you do it, the paint layer becomes smaller by 5 micrometers. From the date of manufacture of the vehicle, no more than 20 polishing procedures can be performed. At this time, you need to use a thickness gauge, especially if the car is used.
Polishing agents
Before you begin restoring the surface, you should make sure you have the necessary materials, such as:
- sandpaper;
- bike;
- foam;
- polishing compounds;
- polish.
Treatment products should be carefully selected. Pastes with abrasive particles are necessary to remove the top varnish layer. They are selected according to the type of cracks and chips on the surface. Preparations with a large number of particles are indispensable when eliminating noticeable defects. Compositions that add brightness to color are quite common.
Cloudy stains often appear on the protective coating of new cars; in this case, you can use a restoration paste that does not contain grinding additives.
A variety of polishes allows you to choose the right product for any task. Thick pastes are suitable for vertical surfaces. They can be used to treat any part of the car. Such products are often characterized by the presence of components that increase the brightness of the shade.
Liquid polishes are only suitable for horizontal surfaces, for example, the hood or roof. The main advantage is the absence of the possibility of damage to the enamel.
Aerosols are quite convenient to use. Such compositions are economical and effective in operation. But it is worth noting that the cans, despite their size, do not contain much material.
Using a polishing wheel
By using a polishing wheel on a drill, you can update the appearance of your car. This procedure is most effective if you need to smooth out small chips or remove tarnishing of the surface.
The work is carried out in 2 stages:
- removing paint from the body surface;
- applying polishing compound.
Protective treatment is also carried out to reduce the negative effects of various types of precipitation and ultraviolet radiation. It is mainly done when preparing a car for sale. A protective layer (it contains wax or silicone) is distributed over the surface of the body to form a film that is invisible to the eye, repels moisture, and makes the body shiny. You can polish a used car with a soft pad if there is no paint damage. It can also be used with careful treatment with a protective agent.
