1. How to judge whether a used car has a body collision?

Nowadays, there are more used car platforms, which reflects a problem, that is, the number of customers buying used cars is increasing year by year. Used cars are different from new cars, so you need to be cautious when buying them. Be careful not to buy used cars after collision repair. Many car owners will encounter such a doubt when buying a used car. A certain used car has been used for a long time, but the body is still shiny and looks like a new car. If the buyer is not a professional, it is likely to be fooled by the seller, thinking that this used car has not been used much. In fact, there is a lot of greasy inside, many used cars look good, but in fact the body has collided many times. It's just that the seller or the platform has done painting, reshaping, or sheet metal repair on the body. After this series of repairs, even vehicles that have collided multiple times will be completely new. In face of numerous tricks, we must understand the detection methods and identify the used cars that have been repaired.

2. How to use paint thickness gauge to test used cars?

One of the more common ways to detect the collision repair of used car bodies is to use paint thickness gauges. The paint thickness gauge can quickly detect the paint thickness of each part of the car body. It can quickly determine whether the car paint has been repaired. In general, the paint thickness of a car is about 100 microns. If the thickness detected by a paint thickness gauge is too large, it is likely that this car has been subjected to secondary paint treatment for body repair. In this case, we must pay attention to be vigilant and not be fooled by the seller or the used car stores.

When using paint thickness gauge, pay attention to the correct method of measurement. When testing the painted surface thickness of used car, pay attention to placing the probe steady and do not shake the paint thickness gauge during measurement. During the test, pay attention to protect the probe, do not hold the probe on the surface, or it may cause damage to the probe, reduce the service life of the paint thickness gauge and affect the future use. If you want the test results to be more accurate, you can measure multiple times and then take the average. If the error before and after the two times is too large, you should pay attention to whether there is a problem in the detection and adjust the instrument in time. 

Customers who buy second-hand cars must remember to check whether the bodywork is repaired or not, otherwise they will be deceived by the surface of the body and buy a used car with many body collisions.
