Is a paint thickness gauge reading of over 1000 microns considered a serious condition?
1 Answers
A paint thickness gauge reading of over 1000 microns is very serious, indicating that the vehicle has experienced severe impact. The typical thickness of automotive paint ranges between 120-180 microns. If the car has been repainted, the thickness will increase. Repainted areas usually measure around 300-500 microns in thickness. If the paint thickness gauge shows a reading as high as 1000 microns, it suggests that the vehicle has undergone body repair work. How to use a paint thickness gauge: With the gauge turned off, press and hold the power button to start it. Reset the gauge's reading to zero. Aim the gauge at the surface of the car paint being measured, maintaining an appropriate distance—neither too close nor too far. Generally, a distance of 5cm is ideal. Read the value displayed on the gauge. For the same paint testing area, measure five points: the four corners and the center. Then calculate the average of these readings. Performance standards for automotive paint: Automotive paint must not only have good mechanical properties, fullness, and high gloss but also excellent adhesion, high hardness, and strong scratch resistance. Additionally, it should possess outstanding weather resistance, scratch and abrasion resistance, gloss retention, and excellent resistance to gasoline, alcohol, acid, alkali, and salt spray.
