GT235 Paint Coating Thickness Meter, Digita Film Coating Thickness Gauge Measuring 0 to 1800um, Tester Painting Depth, LCD Backligh Display with Screen Rotation for Check Car Original Coating

This thickness meter feels high quality and is easy to use and calibrate. The included instructions are well-written and easy to follow. I can see how this meter would be useful for identifying body fillers when buying a used car. But I didn’t get it for that purpose. I do my own auto body repairs and some restorations. I got this meter to help estimate how much I can sand before reaching bare metal. Also, for the panels I spray, I can measure after spraying the base coat, and then again after the clear coat. This gives me reference points for gauging how much clear coat I have to work with if I have to do repairs in the future. I use the same 2-stage/2k coatings on all my work. I always spray 2 coats of base coat, followed by 2 clear coats. I’m hoping a single set of numbers is all I’ll need for everything I do.I tested this meter on my cars. It worked as described in the instructions. I don’t have a feel for the magnitude of the numbers yet, but the relative values of the measurements seem to make sense. Overall, I really like this meter. It’s a nice tool to have if you’re in the market for a used car, or if you do your own auto body work.

I have not had a chance to use this on a car yet but playing with it in the shop it seems good. The kit comes with several plastic chips that you can use for calibrating the machine and a nice pouch. If you are thinking about buying a used car you should take this with you.
