Car paint is generally baking paint, which is often more expensive than white paint, but no matter what color the paint is, the car paint will fade in the sun If you find that the car paint is not evenly faded, but there is a large color difference, it means that the additives in the original car paint are relatively poor, so the effect of stabilizers and antioxidants is not ideal However, good additives are more expensive, but if you pay a high price for paint repair, and the effect of the car body is not long-term, then it proves that you have been cheated Learn to judge the degree of paint damage If the body is not scratched seriously, the scars on the body surface will turn white and have the feeling of scratching In fact, there is no need to touch up the paint in this case You can make more wax or sanding wax If there are still scratches in waxing, you can make another polishing If the scratched surface is serious, the color of the lower primer can be seen generally, and the color of this layer of paint will be darker If the scratched position appears in the bumper, rear-view mirror and wheel arch, it will not rust (because most of them are engineering plastics) It is not necessary to repair the paint in a hurry On the contrary, if it is other parts, it is easy to rust At this time, it is necessary to repair the paint immediately "Original paint" is just a gimmick If you want to paint, the maintenance master suggests that you use the "original paint", then you must not be fooled, because the painting process of the original car will change because of the baking temperature after spraying the paint In addition, the color of the repair paint is allocated before the repair, and the color of the car will change with the service life, so it is very difficult to have 100 percent of the original car paint Therefore, for the treatment of paint scraping, the maintenance personnel will generally spray the whole panel again to prevent the occurrence of color difference At this time, as long as you do not choose inferior paint, the so-called "original factory paint" is a gimmick In addition to the so-called "original factory paint", there are also many claims of imported paint and domestic paint What's more, the inferior paint is used to pretend to be imported paint, and the service life of this kind of paint is very short, and the paint will fall off almost two years later In this regard, consumers can judge by scratching the car paint surface with their fingernails Good car paint generally does not leave scratches, while general car paint will obviously feel very soft, just like a layer of attached paper In addition to the feeling of different texture, the profit difference between imported paint and common paint is also very large If consumers can't identify the trick of changing posts and passing common paint off as imported paint in the repair shop, it will be a big loss Generally speaking, if the imported car exterior paint is about 300 yuan / L, the common paint is about 100 yuan / L; if the imported varnish is 130 yuan / L, the common varnish is 60 yuan / L; if the imported curing agent is 200 yuan / L, the common curing agent is 70 yuan / L, the price of the imported paint is half higher than that of the common paint when the whole car needs more than 2 l exterior paint, 1 l varnish and 0.5 l curing agent Recognition tips if you can't judge the quality of the car paint, you can judge the working environment of the car paint Generally speaking, the baking temperature of the repair paint is about 70 to 80 degrees If you find that there is no special baking room in the repair shop, you are advised to change the place as early as possible, because the lamps used for "heating" cannot work effectively at all It can be said that the regular repair shop adopts the dust-free workshop for painting If the dust in the repair shop is large, it is recommended that you change the place again to avoid bubbles, shelling and other phenomena on the paint surface Common sense: repairing scratches with toothpaste is not a way to repair car paint, but a way to avoid erosion when the cost is more serious The method is very simple The car owner only applies the toothpaste on the scratch, and then applies it with a soft cloth anticlockwise, which can slightly alleviate the trace mark, and avoid the air erosion on the car paint In addition, in order to protect the car paint, some car owners run to make the sealing glaze when the new car arrives In fact, most of the new car paint is coated with a layer of varnish If you do the sealing glaze again, it's totally burning the wallet In a word, the paint surface repair is done when the scratch is serious If it is not repaired in time, it is recommended to apply a layer of toothpaste on the scratch to prevent erosion If it is a lighter scratch, the cheaper way is polishing and waxing, which will make the imprint lighter Finally, when the car owner checks the car, he can scrape the paint surface with his fingernail If there is no imprint, he has no feeling Feel the soft effect, then the surface paint effect is good Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
