The main enemy of the car body is metal corrosion. To combat it, preventive measures and special processing of the metal structure are widely used. It is best to carry out anti-corrosion measures in a specialized workshop, but some of the work is quite within the power of a motorist.
Necessary
- - primer;
- - anti-corrosion mastic.
Instructions
Step 1
Check out the basic ways to combat corrosion. There are three such methods: passive, transformative and active. In the passive method, metal surfaces are isolated from harmful environmental factors. Passive protection is more widespread and can be performed by the motorist on his own. The active method involves the use of special protective substances that are resistant to corrosion. Using a transforming method, the oxidized metal is converted into a kind of primer that is resistant to air, moisture and salt.
Step 2
Using a passive method of combating corrosion, treat the underside of the car with a special mastic. Such compositions are made on the basis of bitumen, resins and rubbers, to which oils and graphite are added. The use of mastic goes well with the factory coating of the car.
Step 3
Try to make the mastic layer thick enough. This is necessary so that stones falling under the wheels of the car do not deform the metal bottom. Technological gaps in the bottom will also need to be treated with an anti-corrosion compound.
Step 4
When choosing a mastic, pay attention to those compounds that have a bitumen or epoxy base. Remember that the use of such coatings requires careful preliminary cleaning of the metal and the application of a primer layer. If dirt remains under the primer, the passive corrosion protection will not be of good quality.
Step 5
After several months of car operation, repeat the treatment of the bottom with mastic, replacing the damaged areas of the primer.
Step 6
When applying mastic to body parts, be careful and attentive. Compounds that prevent corrosion can have a destructive effect on rubber parts such as brake hoses. This directly affects the safety when driving a vehicle.
Step 7
Restore anti-corrosion protection if you have replaced or repaired body parts, as well as after an emergency. If you are not sure that you can do such work yourself, use the services of special centers. Specialists will protect your car from corrosion quickly, efficiently and for a reasonable fee.
