Paint Thickness Gauge CM-205FN for Cars – Digital Coating Thickness Meter, Auto Fe/NFe Detection, 0.1 μm Resolution, 0–1500 μm (0–59.1 mils), ±(3%+2 μm) Accuracy, Backlit LCD

A great tool for the money. I like it !!!

Given the price, this tool is an excellent investment for anyone in auto detailing—especially when you consider how much more expensive future paint repairs could be without it.

Works great! Quick shipping.

Backlight is very nice, and that's why I bought this one. This gauge does the job just adequately for home / hobby use. While it has instructions on how to calibrate, the device will not hold calibration to the controls provided. It is about 5-8% variance with each successive measure. If you need something more precise, you will need to spend more money.

A great tool for the money. It seems to be accurate but it wont work on fiberglass cars like Corvettes. I have used it for many car purchases.

Does what it is meant to do. Nicely packaged and comes with batteries. Easy to calibrate.

This meter easily reads the paint on a car. Are any areas repainted? Plastic body filler buildup underneath? This meter can tell you all you need to know about the finish on a car your contemplating. It reads the paint thickness and repainted cars have a thicker coating on them. Of course, if there’s body filler underneath the paint the number will be quite high. Keep it on you when looking at cars. Put the measuring end on the paint and move around the car. The situation becomes clear. This unit uses a couple AAA batteries and not the coin battery of others. This makes it much cheaper to maintain. Nice tool

If I place this on the same spot I get a different result almost every time that appears be a large spread of results. Tried calibrating but I get the same concern

The item I ordered and received was exactly as described and turned up earlier than I thought it was going to which was great. Highly recommended seller and product.

The reading results depend heavily upon how square you are to the surface. Will a small foot at the reading end, it's a challenge. Might be best set it on continuous mode and slightly tip it around to get the lowest reading. Same idea on convex/concave surfaces. The included calibration plates ensures confidence of the unit itself. I primarily use it for the delta(differences) readings rather than the absolute values.

to get a consistent reading is a challenge. after using the meter for a while i can get better results but if you want better more reliable readings i'd opt for a better meter/gauge.
