The auto paint thickness gauge is mainly used in the used car industry to test the car paint surface thickness. The test data is used to judge whether the paint surface of the vehicle has been sprayed again.
In fact, the paint thickness is related to the model, color and specific parts of the car. For example, the Japanese and Korean car paint thickness will be thinner, while the German and French systems will be thicker. In general, the car paint thickness is between 100 and 180 μm. The thickness of the roof, door panel and front cover will be slightly different.
When we test the paint thickness with the auto paint thickness gauge LS220, the data of the roof is generally used as a reference, because usually the roof is not painted.
The average bare car price of the economy mini-car is usually less then 50,000 RMB. The thinnest paint thickness of the car is not less than 90μm. If the paint thickness tested by the auto paint thickness gauge LS220 is less than 90 μm, the paint thickness quality is not up to standard. For any model with a price above 50,000 RMB, the paint thickness of the car will not be less than 120μm.
Therefore, whether the data measured by the auto paint thickness gauge is high or low is actually related to the car model. Compared with the paint thickness at different positions of the same car, the paint thickness of the roof is generally used as a reference. If the paint thickness is too high, it may be suspected of repainting. If the paint thickness is too low, the accessories may be replaced. For the inside of the car, the paint thickness is generally thinner than the roof. If the paint thickness inside the car is much thicker than the roof, it may be repaired after a serious accident. Generally, the inside of the car needs no repair unless a serious accident happened.
Therefore, when testing the paint thickness with a auto paint thickness gauge, it must be compared with different positions of the same car. It is meaningless to compare between different vehicles.
