The normal thickness of original factory car paint ranges from 80 to 150 microns (um). If the paint thickness falls within this range, it generally indicates original factory paint. Repainted areas typically measure around 250um. How to use a paint thickness gauge: First, calibrate the gauge before use to avoid measurement errors. With the device powered off, press and hold the power button to enter setup mode, then select NFE/FE auto-identification mode. After completing the setup, gently press the probe against the car's painted surface - the display will show the current paint thickness. Important notes when using a paint thickness gauge: Higher readings from the gauge may indicate the vehicle has experienced multiple collisions or severe impacts.

The reading of a paint thickness gauge for original car paint is essentially a measurement of the paint's thickness. Factory paint typically measures around 100 microns, but this can vary depending on the brand and model. For instance, in my decade of auto repair experience, I've measured numerous cars—Japanese models usually range between 80 to 120 microns, while German or premium brands might be 120 to 150 microns due to thicker paint layers that offer better corrosion and scratch resistance. If the reading is unusually high or low, say below 80 microns or above 160 microns, it could indicate repainting or accident repairs, especially if readings vary significantly across multiple points. A paint thickness gauge is a straightforward and handy tool; even an affordable handheld one can quickly reveal the truth by checking spots like the hood or doors. Remember, new cars leave the factory with consistent readings—significant deviations suggest potential issues that could affect resale value. Maintaining original paint not only enhances appearance but also boosts durability; regular washing and avoiding prolonged sun exposure help.

I've measured many factory car paints with a paint thickness gauge, and the readings generally fluctuate around 100 microns. Through my car hobby experience, I've noticed significant variations between different car brands: Toyota and Honda usually range between 90-110 microns, while BMW and Audi can reach up to 140 microns with harder, more wear-resistant paint quality. When measuring, always choose flat areas like the center of the hood, avoiding seams or edges to ensure accurate readings. Operating a paint thickness gauge is simple - even affordable devices costing just tens of dollars can provide results within seconds by gently placing the probe against the surface. Consistent original paint values indicate no major repairs, which is crucial for maintaining a car's resale value. When I inspected a used Corolla, the uniform 110-micron readings confirmed original factory paint, so I purchased it without hesitation. For daily maintenance, avoid scratches from hard objects - maintaining stable original paint values makes the car more durable and saves significant repair costs.

The original factory paint thickness gauge typically reads between 100-140 microns. When measuring, use the tool to check several key points and take the average. When I inspect a car myself, paying attention to this value can reveal whether the paint has been resprayed. Uniform and consistent readings indicate intact original paint, while abnormal fluctuations may suggest accident history. Paint thickness relates to vehicle surface protection, with factory-set values balancing aesthetics and durability—no need to worry if within normal range. Regular maintenance like waxing protects the paint surface, and stable readings help maintain vehicle value. Simply put, 100 microns is a common benchmark.
