Using a car paint tester, also known as a paint meter, is straightforward: simply press the device firmly against the car's body panel to take a reading of the paint thickness in mils or microns.
Here's a breakdown of the process:
-
Turn on the Paint Meter: Most meters have a power button. Turn it on and allow it to calibrate, if necessary (some meters self-calibrate).
-
Select Units of Measurement: Choose between mils or microns, depending on your preference and the meter's settings. The referenced video mentions using either. Most meters allow you to switch between the units.
-
Position the Meter: Place the paint meter's probe (the part that makes contact with the car) perpendicular to the surface of the car panel you want to test.
-
Take a Reading: Gently but firmly press the meter against the panel. Make sure the probe is making full contact with the surface.
-
Read the Measurement: The paint thickness will be displayed on the meter's screen.
-
Repeat: Take multiple readings across the panel, especially in areas you suspect may have been repaired or repainted. This will help you identify inconsistencies in paint thickness.
Important Considerations:
- Clean Surface: Ensure the surface is clean and dry before taking measurements. Dirt or moisture can affect the accuracy of the readings.
- Calibration: Periodically calibrate the meter according to the manufacturer's instructions to ensure accurate readings.
- Interpreting Readings: Understand what the readings indicate. A significantly higher reading than the factory paint thickness typically suggests that the panel has been repainted or has body filler underneath. Knowing the factory paint thickness for your specific vehicle model is useful for comparison.
- Different Materials: Some paint meters are specifically designed for use on steel or aluminum. Make sure your meter is compatible with the material of the car panel you are testing.
