Second-hand car maintenance tips: paint inspection and maintenance. The car will inevitably be bumped or scratched during use, and it needs to be painted to compensate. So when purchasing a second-hand car, don’t worry if you have done the paint, but pay attention to the quality of the paint. You can choose the “hands and eyes” method. It’s worth clarifying that: second-hand cars have some local routines of paint seal factory, which will not have much influence on the quotation of second-hand cars, but the painted parts can be used to judge whether the second-hand car is severe or not. Traffic incidents that severely affect vehicle functions. Some are painted: usually due to the damage of the body paint surface caused by the small mechanical seal factory bumping, and some are used as the paint. In addition, sheet metal is required after the body is damaged, and it will be painted in the future. Paint the whole car: Due to the aging of the paint, bumps, and accidents, it is necessary to paint the whole car. There are several ways to investigate whether the vehicle is painted or not: 1. Look at the light reflection and chromatic aberration: The light and dark contrast of the reflected light of the car body is used to determine whether the pump is painted with a mechanical seal. Usually, the local reflection light of the paint is very dark. However, some high-end cars are painted at the special repair station designated by the manufacturer. Computer color matching, paint matching, and varnishing. The quality of the paint is very good and it is not easy to investigate. Regarding metallic paint, you can check the amount of metal in the paint. Of course, users of cars with good paint quality don't need to mind. The color difference of the car with poor paint quality is more obvious, and the user can see it. 2. Feel the smoothness by hand: the local feel of the paint will not be smooth, and the unevenness of the body can also be felt. 3. Investigate whether there are traces of sandpaper polishing: After scraping the putty and sanding with sandpaper, there will be traces, with many thick or thin stripes, which are different from the original car paint that is perfect around the paint. 4. Hit the car body to judge: the sound of the sheet metal parts should be lower, because the thickness of the putty is different from the original car paint. 5. Pay attention to the edges, decorative strips and rubber seals: see if there are traces of residual paint and 'flowing paint'. 6. Open the machine cover: check whether there is any residual paint and the color difference with the body paint. In short, painting mainly includes 'painting by scratching' and 'painting after collision with sheet metal'. It is also recommended that car owners go to the 'painting room' of the manufacturer's repair station to paint for better quality. Special reminder: If your car only has some slight scratches and non-severe bumps, you don’t need to go through insurance to paint frequently, because paint will affect the purchase price of second-hand cars, so paint is used to take into account the 'skin'. When it comes time to sell the car, it will be lost. Keywords: seal factory, mechanical seal factory, pump mechanical seal
