The article mainly uses the auto paint thickness gauge to test Citroen DS.We can know how to use the auto paint thickness gauge to measure the car paint thickness.After knowing the car paint thickness,we can compare the data and find which part has been repainted.

     The Citroen DS is a good model.The adjustable seat and steering wheel are ergonomic.The most prominent design of the R320 is his air suspension system.This suspension system,coupled with the steering assist system of the R-Class,allowing the driver to navigate the narrow streets. The sound insulation of this model is also very good, even if the speed is raised to a certain extent,the noise generated is very small.It is precisely because this car is good overall, so many people choose.The price of the new car is about 610,000 RMB,because the price of the new car is relatively high.Therefore,some people choose a second-hand car with a relatively high cost performance.So how do you estimate the used car?The paint surface thickness of the Citroen DS is tested by the auto paint thickness gauge to determine whether the car is an accident car.

    The following figure shows the paint surface thickness at 17 locations of the Citroen DS body tested by the auto paint thickness gauge.The positions are: roof, engine compartment cover,left front fender, left A-pillar, left front door, left B-pillar, Left rear door, left C-pillar, left rear fender,trunk lid,right rear fender,right C-pillar,right rear door,right B-pillar,right front door,right A-pillar,right front fender.These 17 locations are all over the car and the measured data can be used to analyze the overall condition of the car.
    The following is the specific test data of the Citroen DS paint surface thickness tested by Linshang auto paint thickness gauge,the unit is μm:

   13.The paint surface thickness values of the Citroen DS right rear door are:
86.3, 83.9, 79.6, 81.5, 86.1, 76.8, 79.1, 79, average: 81.5, minimum: 76.8, maximum: 86.3.
   14.The paint surface thickness values of the Citroen DS right B-pillar are:
94.8, 93, 97.9, 97.7, 97.1, 96, 92.8, 92.3, average: 95.2, minimum: 92.3, maximum: 97.9.
   15.The paint surface thickness values of the Citroen DS right front door are:
498, 336, 251, 202, 194, 194, 199, 205, average: 259.9, minimum: 194, maximum: 498.
   16.The paint surface thickness values of the Citroen DS right A-pillar are:
98.5, 95.3, 98.5, 99.2, 94.3, 100, 96.6, 96.7, average: 97.4, minimum: 94.3, maximum: 100.
   17.The paint surface thickness values of the Citroen DS right front fender are:
107, 106, 109, 111, 104, 113, 116, 119, average: 110.6, minimum: 104, maximum: 119.
    We generally judge whether the car body has been painted with sheet metal,mainly compared with the original paint of the car.Usually,the car roof won't be scratched. Take a few points evenly on the roof, measure the average value of each point 3 times and then take the average value of these points.The film thickness at this point is used as a reference value.The data is normal when it only exceeds 10-40 μm.
    From the test data of the Citroen DS,the average value of the left B-pillar:1497.4,the average value of the right B-pillar:1223.6,the average value of the right rear door:176,the average value of the right C-pillar:252.1,right Average value of rear fender:240.1,average of trunk lid: 188.5.It can be seen that the two places where the data is relatively large,the positions may have been repainted. 
   It can be seen from the above measurement examples that the auto paint thickness gauge can help the used car dealer to find the repair position and repair degree of the car paint surface.
