Directions: Measuring Thickness

The measurement the tool uses takes place be signaling between the metal surface you are working on and the magnet that resides in the device, the resulting measurement it the thickness of the layers in-between. Measurements are in micrometers "μm" which is an imperial measurement form for 1/1,000,000 of a meter, the American equivalent would be mils measuring in at 1/1,000 of an inch.

1 μm = 25.4 mils

So when using this device to measure it is important to keep in mind these numbers when determining thickness of a vehicles Primer, Base Coat, and Clear Coat;

0-100 μm = Thin Layering [Cause for Concern]

100-180 = Standard Car Paint Layering [Good]

180+ = Thick Layering [Great, unless the car has been repainted, then it may be a concern]

When measuring car paint coating thickness in micrometers (μm), the values can vary based on factors such as the type of coating, application method, and specific automotive requirements. Here are some examples of different μm measurements for car paint coatings:

  1. Primer Coat: Typically ranges from 5 μm to 40 μm. This layer prepares the surface for subsequent coats and enhances adhesion.

  2. Basecoat (Color Coat): Usually falls within the range of 10 μm to 40 μm. The basecoat provides the color and appearance of the vehicle.

  3. Clearcoat: Approximately 30 μm to 80 μm. This layer protects the underlying layers and contributes to the gloss and durability of the paint.

It's important to note that these values are approximate and can vary between different car manufacturers, paint systems, and specific applications. The one drawback of this tool is it gives you the total thickness and not how thick each layer is (Primer, Base, & Clear), those tools are very expensive. What it does best is gives you a great groundwork to determine how thick of a surface you are working with before you start detailing, which helps in avoiding unseen issues that come from uneven coatings, thin layering, or inadequate coverage!
