What is the normal range for paint thickness gauge readings?

[DeKhloe]

The normal reading for a paint thickness gauge is between 120 and 180 microns. The paint thickness gauge is primarily used to measure the thickness of a car's paint surface, helping to determine whether the vehicle's paint needs to be redone. Place directly on the car paint: Using a paint thickness gauge is very simple. After turning on the device, place it directly on the car paint surface. Within about one second, the screen of the paint thickness gauge will display the thickness of the paint. First, inspect collision-prone areas: When measuring with a paint thickness gauge, ensure the probe is perpendicular to the measurement surface to avoid significant errors. During vehicle inspection, start by checking areas that are prone to collisions.

I've been in auto repair for over a decade and used many paint thickness gauges. Normally, the original factory paint thickness on new cars ranges between 80 to 150 microns. If the reading falls within this range, it's fine. If it exceeds 200 microns, it's likely that the car has been repainted for repairs, possibly due to accidents or color changes. Readings below 60 microns indicate the paint is too thin, making it prone to rust or bubbling. Older cars tend to have lower readings, especially if poorly maintained. I recommend checking every six months, and don't just focus on the door panels—measure the hood and roof too. Using a paint thickness gauge when buying or selling used cars helps avoid pitfalls; differences of hundreds of microns could indicate issues. Remember, consistent readings are best—avoid fluctuating values.

I usually enjoy playing with cars, and whether buying a used car or changing to a new one, I always bring a paint thickness gauge to measure. The normal value is generally around 80 to 150 microns. If it's too high, say above 200, the car has probably been heavily repainted—factory paint wouldn't be that thick. If it's too low, below 60, it means the paint has severely aged, and without protection from wind and sun in the parking spot, it will deteriorate quickly. I’ve noticed that higher values on the front and rear bumpers are normal, but consistency on metal parts is key to ensuring the paint lasts longer. I often DIY measurements for fun—it’s quite interesting and helps prevent potential issues.

I'm in the car detailing business, focusing on paint health. The normal reading for a paint thickness gauge is 80-150 microns, which is optimal for protecting the car body. If it's too thin (below 60 microns), it accelerates corrosion and oxidation, and waxing won't help; if it's too thick (over 200 microns), it risks uneven repainting or bubbling. Regular inspections can prevent long-term abnormal readings that lead to increased repair costs. Be gentle when washing and scrubbing to avoid affecting the paint thickness.
