Auto Paint Thickness Gauge Test Mercedes-Benz R320 Paint Thickness

Mercedes-Benz R320 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,allows 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 model of the car is good overall, so many people will choose it. The price of the new car is about 610,000 RMB, because the price of the new car is relatively high. Therefore, some car owners choose a second-hand car with a relatively high cost performance. So how do you estimate the used car? The Mercedes-Benz R320 paint surface thickness is tested by an auto paint thickness gauge to determine whether the car is an accident car.

The following figure shows the paint surface thickness at 17 positions of the Mercedes-Benz R320 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 can be used to know the overall condition of the car.

    We generally judge whether the car has made sheet metal by comparing the test data with the original paint thickness.
    The roof paint thickness can be regarded as original paint thickness because of the probability of an accident on the roof is smallest. Take a few points evenly on the roof, measure the average of each point 3 times and then take the average of these points. The film thickness at this point is used as a reference value. This method is also a reference method for measuring the film thickness at other positions of the vehicle body. The general measurement data exceeds 10-40 μm and is normal.
    From the test report of the Mercedes-Benz R320 measure by Linshang auto paint thickness gauge, 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 from the measurement data that this Mercedes-Benz R320 may have been treated with sheet metal painting. Therefore, the part where the measurement data is relatively large should be checked.
    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.
