This paper will analyze the paint surface thickness data of 17 parts of Lexus GX460 through bluetooth coating thickness gauge to analyze whether used car is repainted or made sheet metal repair.

    The Bluetooth coating thickness gauge adds Bluetooth data transmission function to the ordinary coating thickness gauge. With a dedicated mobile phone APP, you can view test data and generate reports on the mobile phone. The latest LS220B from Linshang Technology is a Bluetooth coating thickness gauge that can record multiple sets of data. The instrument is designed as integrated type and it is a handheld thickness gauge.
    This time, we used a second-hand Lexus GX460 as an example to measure the paint thickness at different positions of the car using a Bluetooth coating thickness gauge. And then we can analyze whether the used car was repainted or sheet metal repaired.

   The above picture shows the used Lexus GX460. We used the Bluetooth coating thickness gauge LS220B to measure the following 17 positions of the used car: the roof, the engine compartment cover, the left front fender, the 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.

    8.The thickness of the left C-pillar paint surface of the Lexus GX460 car are:
131, 131, 125, 122, 125, 122, 142, 130, average: 128.5, minimum: 122, maximum: 142.
    9.The paint thickness values of the left rear fender of the Lexus GX460 are:

   11.The paint thickness values of the right rear fender of the Lexus GX460 are:
128, 125, 123, 124, 120, 121, 129, 131, average: 125.1, minimum: 120, maximum: 131.
   12.The paint surface thickness of the right C-pillar of the Lexus GX460 car are:
127, 126, 125, 129, 130, 134, 135, 130, average: 129.5, minimum: 125, maximum: 135.
   13.The paint thickness of the right rear door of the Lexus GX460 car are:
181, 189, 201, 206, 212, 183, 170, 171, average: 189.1, minimum: 170, maximum: 212.
   14.The Lexus GX460 car's right B-pillar (outside B-pillar) is non-metallic and has no test data.
   15.The paint thickness on the front right door of the Lexus GX460 car are:
139, 130, 113, 127, 125, 148, 139, 121, average: 130.3, minimum: 113, maximum: 148.
   16.The thickness of the right A-pillar paint surface of the Lexus GX460 car are:
121, 122, 122, 141, 134, 135, 127, 123, average: 128.1, minimum: 121, maximum: 141.
   17.The paint thickness values of the right front fender of the Lexus GX460 are:
159, 157, 153, 174, 153, 161, 165, 149, average: 158.9, minimum: 149, maximum: 174.
     With the 17 sets of data obtained by the integrated Bluetooth coating thickness gauge, it is not difficult to find that the average paint thickness at multiple locations is quite different. At this time, we can use the paint surface thickness of the car roof as a reference value to analyze the thickness of other parts. The average thickness of the paint film on the engine compartment cover, the left front fender, the left front door, the left rear door, the trunk lid and the right rear door is slightly higher than the average paint thickness of the roof. The car has been subjected to some scratches and repainting. It is inevitable that the car is scratched during use, which is a common phenomenon in used cars.
     However, when measuring the left rear fender, the average thickness of the paint film was more than one thousand. This value is much higher than the thickness of the original paint. It can be judged that this is caused by the repair of the sheet metal after the car has been scratched.
     Through the above data analysis, we don't know if you have learned how to use a Bluetooth coating thickness gauge to judge the paint thickness of used cars. We will also introduce more test cases for different car models. If necessary, you can pay attention to our following update.
