Paint Thickness Tester Meter Gauge, Paint Coating Tester, Car Body Damage Detector, Crash-Test Check, Water Resistant, Great to Have When Shopping for Used car

I use this pen magnet to detect hidden bondo in classic cars we buy. It clicks nicely onto the metal and immediately shows trouble spots. It’s compact enough to fit in a pocket or bag, about the size of a regular pen. I prefer this over a fridge magnet since those always seem to go missing. The built-in clip helps keep it secure, making it a reliable tool to have on hand.

Good 👍

If you are buying a new vehicle I would highly recommend picking this pen up when going to go look at it and watching a quick video on how it works. It’s great for detecting bondo patches that sellers might not want you to know about. 10/10

If you are here reading this review, you know that many of the contemporary "digital" paint thickness meters cost easily 5-10x what this does.This is certainly the "old school" way of doing things, and there is a trade off for not paying the extra money.Right off, I was "testing" this gauge on both multiple vehicles (some of relatively known thickness, factory paint jobs), items I estimated the thickness, as items (vehicles) I had painted that I also estimated the thickness.I found variation in the paint thickness where I anticipated, at peaks and on vertical surfaces.Then I tested it on raw metal and it did not perform as I anticipated, as it SHOULD become fully extended on raw metal.I was about to return it and then, after a couple more experiments, realized that you have to be very careful and linear if you want an accurate reading.As in, you have to pull the meter back slowly and DO NOT MOVE laterally, or it will release.You HAVE to remain perpendicular to the surface if you want to get any sort of consistency/accuracy, as any tilt off being perpendicular is going to change the tension of how the magnet moves in the barrel, and cause it to disengage too soon.Granted, this is old school technology.Instead of expecting to get any type of high accuracy without really perfecting the technique it requires to use this tool, I think it's best to expect to find an average where you can gauge your own style of measuring to how the tool works.Try using it on raw metal first if you can, and you can get used to the best practices to utilize this tool.**UPDATE**Yes, it may be a general reference but it occurs to me that, even on bare metal, I have NEVER been able to get it to reach the blue section of the gauge. I have tried many, many times.This tells me that the mechanism [spring] that holds the magnet is not very consistent.Still, you can use it as a general reference, and that is about it.Make sure to test your individual unit to see how it actually operates, because apparently there's no guarantee as to accuracy.

Es funcional y practico al momento de comparar un vehículo, creo que todo concesionario debería tenerlo.para no recibir carros altamente accidentados.

Good product

This tool excels in checking uniformity of paint thickness. Easy to use and easy to learn. It works really well to determine areas that might be different paint thickness from the rest of the car. If the readings are near equal in every area chances are that the paint is either factory or the entire car has been professionally resprayed. It will also alert you to areas that might have body filler underneath the paint.This is a PERFECT tool to take with you when looking at new or used cars on the lot...looks like you have an ink pen in your hand.

Me resultó bastante , pude hacer las pruebas necesarias
