With active use, the car is inevitably exposed to small pebbles that scratch the decorative coating. If the crack is large enough, it can cause metal corrosion in the future. In order not to worry about the fate of the car, you need to purchase a reliable anti-gravel composition, for example, Body 950, which will help to avoid such troubles.

Antigravel - what is it?
Most often, fine sand, gravel and stones, frozen snow strike bumpers and the walls beneath them, along the bottom of the doors, the thresholds of the car and its bottom. It is on these parts that it is recommended to apply anti-gravel - a car chemistry product used to protect body parts from mechanical damage. Such compositions prevent scratches and cracks in the paintwork, thereby preventing corrosion. They are based on synthetic resins, rubber, polymers, improving additives and additives, as well as phenol and urea.
Polymer coatings of the “anti-gravel” type really help protect the integrity of vulnerable areas of the machine. After application, they form a matte film that retains plasticity even at temperature extremes, is durable, does not scratch, does not tear and does not crack. Antigravel really extends the life of parts, moreover, it is a preventive measure against aggressive chemicals and moisture, it provides additional soundproofing protection (reduces the noise level).
The most famous brands of antigravia are UBS, Dinitrol, Novol, Tectyl, but Body is the market leader. Under this brand a whole line of products is produced, here are the most popular:
- HB Body 951 - a black rubber-based compound that is particularly resistant to salts;
- HB Body 900 - a colorless or brown waxy composition having high soundproofing properties;
- HB Body Proline 650 - anti-gravel with sealing properties.
Area of use
Mastics, gels, compositions in spray cans for a gun or in aerosols of the “anti-gravel” type are most often used to treat the bottom from damage on the road. They are also great for protecting arches, sills, bumpers, although some car owners for this purpose prefer anticorrosive and movil, considering them more reliable with respect to anticorrosion properties.
to contents ↑In addition to body treatment, anti-gravel can be applied to parts of yachts, boats, boats and other water vehicles that come into contact with water. The coating will be so strong that it will maintain integrity for a long time and provide reliable protection against damage.
Expediency and application features
The composition of Body 950 anti-gravel is recommended for those who often drive a car on bad roads, go hunting, fishing, hiking and traveling. Nevertheless, before applying it is important to clarify whether an anti-gravel layer was already made at the production stage: for example, on Russian cars this protection is applied with the last layer of paintwork. This helps to reduce the risk of chips, small cracks, scratches, allows you to easily operate the machine in difficult conditions.
Anti-gravel Body 950 is available under different articles in three colors: white, gray, black. For ease of application, it is in the form of an aerosol. After a certain preparation of the body, the composition is sprayed onto the surface in 2 layers with intermediate drying until completely dry. Some users note that to give a metallic shade it is necessary to process the base with sandpaper No. 350.
HB BODY 930 Anticorrosion composition: characteristics
The composition of Body 930 Bitumen based on bitumen, resins, rubber and corrosion inhibitors is available in liquid form, applied with a brush or a special gun. The instructions for use indicate that before performing work it must be diluted with a nitro solvent in the amount of 10-20%. This mastic has anticorrosive properties, provides protection to the underbody of the car from rust and mechanical damage, and provides a soundproofing effect.
The product is flexible, does not deteriorate from temperature changes, salt reagents, durable and practical, suitable for internal and external elements of the car. The main characteristics of the Body 930 are as follows:
- black color;
- density - 1 kg / l;
- solids content - 65%;
- layer thickness - 0.5-3 mm;
- flash point - 0 degrees;
- thixotropy - high;
- the possibility of staining - is;
- resistance to UV radiation - high;
- volume - 400 ml, 1 l.
HB BODY 950 Antigravel: features
Body 950 anti-gravel coating is flexible, textured, easily painted with any kind of automotive paint (including the wet-by-wet method - without grinding and intermediate drying). The product has a black or gray color, has a high level of noise absorption, gives excellent protection against sounds in the cabin due to the sealing properties.
The composition characteristics are as follows:
- operating temperature range -30 ... + 95 degrees, maximum temperature of short-term exposure +110 degrees;
- layer thickness - up to 1000 microns;
- drying time with the specified layer thickness - 16 hours;
- dry residue - 40-45%;
- density - 1.05 g / ml;
- flash point - about +9 degrees.
Mode of application
Before starting work, you need to prepare the car, purchase all the necessary tools, consumables, read the instructions for the composition.
Tools and accessories for working with anticorrosive
You can work with anti-gravel in any room, the main thing is that in the cold time of the day the temperature in it should not drop below +8 degrees. Otherwise, the quality of the protection will drop, and the drying time will increase. It is necessary to take care of personal protective equipment: wear a suit made of thick fabric, a respirator, glasses and gloves. A headpiece is also required: this composition is removed very poorly from the hair.
The list of accessories for working with anti-gravel is as follows:
- spray or brush (if the composition is not in an aerosol);
- a device for installing the machine on one side (when there is no inspection hole or lift in the room);
- degreaser.
to contents ↑The lighting in the garage should also be good, otherwise the layer may come out uneven, and some places will remain unpainted. During operation, ventilation with good ventilation should be organized without drafts, gusts of air. If the composition is applied on the street, a dry day without wind, dust is chosen.
Surface preparation
Before performing the coating, you must carefully prepare the base. Otherwise, the protective film will not last long, and the dirt that remains under it will begin to corrode the metal even faster. As a result, corrosion will appear on the body with a higher probability than it would be without antigravel treatment.
As preparation measures, the following is carried out:
- rinse the treated area with detergents;
- subject the painted parts to matting (sandpaper processing to create a relief in order to enhance adhesion) or completely clean off the paint;
- if necessary, sandblasting can be carried out for the bottom;
- seal dents with car putty, putty, fiberglass;
- treat the existing corrosion places with particular care, grinding all the rust;
- cut out rotten areas, weld “patches” from metal;
- do degreasing (immediately before applying anti-gravel).

Work with the composition
It’s inconvenient to work with a brush, besides, the process will take a lot of time. It is better to purchase the composition in the form of an aerosol or use a spray. The product is applied in 2 even layers, allowing each to dry "on the stick." In hard to reach areas you can use small brushes. Before operation, the car must be kept up to 16-24 hours.
Pros and cons
The tool has unique properties: after drying, it creates a film on the surface of the machine that reliably protects the metal from rust, shock and chips. Even when pebbles slide along the bottom, there will be no scratches on it. The advantage is the long service life of the composition, its high quality and affordable price, as well as ease of application.
The disadvantages include the need for a long and thorough preparation of the base, otherwise anti-gravel will serve poorly - it will accelerate the appearance of rust. To apply the composition, it is worth buying a spray gun, covering the body with a brush is longer and harder. But with full compliance with the instructions and periodic repetition of work, the composition guarantees a high degree of protection and getting rid of unnecessary problems!
