Although the data detected by the paint thickness gauge is only a reference, other situations require more experience to judge, so when you buy a used car, you need a professional second-hand car appraiser to assist. The paint thickness gauge is the most commonly used instrument in the hands of used car appraisers. It is a tool used to judge the thickness and sheet metal of the used car paint surface. All car surfaces are covered with paint coating and the paint thickness gauge can directly detect whether the car has been repaired or painted.
The thickness of the original car paint is generally 100um-180um. But in the used car market, in order to make the car look better, the seller will usually make car beauty.
When using the paint thickness gauge LS220 to test the surface of the used car, sometimes the thickness of the paint at a certain part is higher than the original paint, indicating that it may be caused by the second paint. This happens generally because the car has been scratched, but it does not have any other impact on the car.
When testing with the paint thickness gauge LS220, first test the thickness of the original paint of the car on the roof and then test the paint thickness of the engine compartment cover, the door, the side fenders and other positions. If the data tested is quite different from the data on the roof, be cautious when purchasing.
