What is the standard paint thickness on cars?

Checking the thickness of the paint on a car with a coating thickness gauge is easy. For most gauges, you simply have to touch the end of the probe onto the surface of a car's panel. It will then give you a reading of what the thickness of the coating on the panel is.Feb 3, 2020

How many microns should car paint be?

Ultimately this tells us the total thickness of the various layers on most modern cars is between 67 microns (µm) and 198 microns (µm). If you come across a panel or panels where the total depth is greater than 198 microns (µm), it is a strong indication the vehicle has been resprayed.Oct 8, 2019

How is paint depth measured?

Digital paint thickness gauges work by measuring the distance between the body panel and the sensor on the device. That distance measured is the overall thickness of the paint (primer coat, base coat, and clear coat). Most paint thickness gauges can work on metal and aluminum car panels only.

What is paint thickness measured in?

In the U.S. the thickness of paint is expressed in mils (one mil equals 1/1000 of inch). The rest of the world expresses coating thickness in microns (1 micron = 1 millionth of a meter and 25.4 microns = .Nov 21, 2014

What is good paint thickness?

A typical factory paint job will measure between 4.0 mils and 6.0 mils. The clear coat will generally measure between 1.5 and 2.2 mils thick. The alternative measurement is called a micron. A micron is a metric unit that equals one millionth of a meter, or 1/1000 of a millimeter.

What is a good paint meter reading?

Lastly, we have found average paint jobs to be anywhere from 4.0 to upper 4s or 5.0 Mils, depending on the make, model, etc. In all my years of detailing, I've seen some OEM paint that's as low as 3.5 Mils or so and then others upwards of 8-9. The thicker ones are usually higher end cars, like Bentley, Ferrari, etc.Jul 7, 2014

How thick should paint be before polishing?

A paint thickness reading of 100 µ (Microns) is reasonably safe for polishing.Jul 29, 2011

What is a mil paint thickness?

1 mil is equal to 1 one-thousandth of an inch (25 microns). The mil thickness of a coating not only effects the appearance of a coating but also the performance and protective qualities.

How do you measure paint thickness in microns?

1µm (micron) = 1/1000mm so when you get up to 1000µm your coating will be 1mm thick. In the USA they tend to use Mil or Thou as their form of measurement, 1 Mil = 1/1000th Inch. 1 Mil / Thou = 25.4 Microns (µm).Sep 15, 2015

How the coating thickness is measured?

Two measurements must be taken: one with the coating in place and the other without. The difference between the two readings, the height variation, is taken to be the coating thickness. On rough surfaces, micrometers measure coating thickness above the highest peak.Sep 13, 2021

How to measure car paint depth using a paint thickness gauge?

  • Today, I’ll show you how to measure car paint depth using a paint thickness gauge and what you should check when measuring the paint thickness. To check the paint thickness on your vehicle, lean the coating thickness gauge sensor to the surface of the panel you want to measure.


How thick should paint be on a new car?

  • There’s no definitive answer to how thick paint should be on any vehicle. Each vehicle is different, even from the same manufacturers. However, there are some general rules you should follow. Most new cars will have a paint depth of around 100-150 microns or about 4-6 mills, depending on what unit you use to measure the thickness.


How do you measure paint thickness over steel?

  • Since steel is magnetic, paint thickness over steel is measured with magnetic (ferrous) gages employing mechanical or electronic operation. Mechanical gages use a permanent magnet, a calibrated spring, and a graduated scale. By measuring the force required to pull the magnet off the coated surface, a thickness measurement can be determined.


Why is the paint on a scraped car so thick?

  • If the measured data is only a little higher than the thickness of the original car paint, it may be caused by the repainting of the car after being scraped. If the thickness of the paint surface increases, it is much higher than the thickness of the original paint. Then the car may had a serious accident and has made sheet metal.
