Avilon listed 4 factors that destroy paint on used cars

The paintwork of used cars often swells. According to Vadim Strelbitsky, director of the mechanical repair department at Avilon Kia, the reasons may be rust, poor-quality body repairs, or errors in car care.

“The most typical situation develops like this: first, moisture gets under the paint through small chips and scratches. Then a corrosion process begins on the metal and rust appears. As rust grows, it takes up more and more space under the paintwork and simply squeezes it out, which leads to swelling,” the expert explained.

If the car was repainted in violation of the technology – for example, the surface was poorly prepared, cheap materials were used, or layers of the wrong thickness were applied – bloating is inevitable, says Strelbitsky. Even if the work looks good from the outside, hidden defects will sooner or later appear.

Another reason is the aggressive environment. Reagents, salt, sudden temperature changes and ultraviolet radiation gradually destroy the paint layer, especially if it is already weakened, the specialist added. Constant exposure to these factors compromises the integrity of the coating and makes it vulnerable to blistering.

And finally, the use of harsh chemicals, infrequent washing or, conversely, too frequent washing with aggressive agents – all this accelerates the destruction of the coating, the expert warned.
