Review: On Used Car Purchase This Device Provided Peace of Mind & Saved Me Thou$ands - I had seen this simple device demonstrated on YouTube. Watching it in action I was sold. Bottom Line First: How did this save me thousands? Well think about it. In regards to the car's body, we buy a used car AS-IS in that regard. (I do not know of any car lot who warrants a vehicle's history; i.e., the car you are considering is accident and collision free. IOW, in regards to a car's body, what you see is what you're buying.) Not using this device is the horror of all horrors: You proudly arrive home in your dazzling new-used car. You then after-the-fact use this device to test the metal and paint. Oy vey! You find out the fine looking left rear quarter panel (see pic) is comprised mostly of Bondo, fiberglass, and tape. I guarantee this discovery will throw you into a depression with the thought that you're stuck with a car that has instantly decreased in value because you just know a subsequent buyer is going to use his test meter BEFORE he agrees to buy it, and he is not going to pay retail on a car that's been in an accident or had body work done on it. As to myself, after I received this paint test meter I immediately put it to use when shopping for a 2018 certified pre-owned Toyota RAV4.* I used my new gauge/meter at the Toyota dealership where I was planning to buy a fine nice looking RAV4 example. (See pic). Despite looking sharp, I, like you, was wise enough to know that looks can be deceiving. So I whipped this out and got to work. This test meter worked perfect. Within minutes I was able to test all RAV4 surfaces, checking for Bondo, after-market paints, and confirm each section was OEM, so to speak. A real hoot was my interaction with the salesman, who was watching me with mouth open while I tested the RAV4. At a point he even asked if I was a buyer for another car lot, or perhaps an auto broker finding cars for private clients. Note on use: This is very very easy to use. The magnet, spring, and color gauge are precisely calibrated to measure paint thickness and tattle if a car has after-market paint, indicates factory paint, and tattle if sections of the car have Bondo or other filler instead of metal. It's also easy to test whole sections of the car to determine if a fender, for example, is after-market sheet metal. In this regard SLOWLY pull out the gauge to prevent getting a false reading. Also, make sure to check every section of the vehicle, high, in the middle, low, and the back. WARNING: Perish the thought that you don't need this device, because you checked the car's history in a report online, and it said there were no accidents reported. THE OPERATIVE WORD IS: REPORTED, because it is common knowledge in the auto industry that NOT all accidents are reported to the DMV, and NOT all car damage goes into a car's history, e.g., in a history report generated by CarFax. Often times, damage to a vehicle is repaired "under the table" without involving the police or insurance company. Moreover, many reported accidents may slip under, e.g., CarFax's radar, nor may CarFax may be up-to-date. Don't take my word for it. Consider on every CarFax web page the Company warns: CARFAX Vehicle History products and services are based ONLY on information supplied to CARFAX. CARFAX DOES NOT have the complete history of every vehicle. Use the CARFAX search as ONE important tool . . . to make a better decision about your next used car. That's it, enjoy guys. I LOVE my testing meter.
Review: Excellent Tool for Car Inspections - I purchased this paint thickness gauge to evaluate a used car before buying, and it was absolutely worth it. It easily revealed which panels had been repainted or repaired with filler. The device provides precise readings and is incredibly easy to operate.

## Features

- HIGH ACCURACY — READY TO USE FOR CAR INSPECTION: Professional paint thickness gauge with factory-calibrated accuracy for automotive inspection. Delivers precise measurements immediately after battery installation — no calibration required for car body checks. Resolution 0.1 μm (0.01 mils), range 0–1500 μm (0–59.1 mils).
- EASY & FAST OPERATION — NO SETUP REQUIRED: Automatic substrate detection and pre-set factory calibration allow instant use out of the box. Large backlit LCD and intuitive controls make this coating thickness meter ideal for both professionals and first-time users.
- AUTOMATIC Fe / NFe / Fe+Zn SUBSTRATE DETECTION: Automatically recognizes steel (Fe), aluminum (NFe), and galvanized steel (Fe+Zn). Fe+Zn detection helps identify replaced or non-original car body panels during used car inspection.
- DESIGNED SPECIFICALLY FOR AUTOMOTIVE INSPECTION: Accurately evaluates paint thickness, repainting, and filler presence on metal car panels. Ideal for used car buyers, vehicle appraisers, body shops, and detailing professionals.
- DUAL MEASURING TECHNOLOGY FOR METAL SURFACES: Uses magnetic induction for ferrous metals and eddy current technology for non-ferrous metals, ensuring stable and repeatable measurements on steel, aluminum, and copper substrates.
- SINGLE & CONTINUOUS MEASUREMENT MODES: Supports single-point (SNG) mode for precise spot checks and continuous (CON) mode for rapid scanning of large vehicle panels.
- OPTIONAL ADVANCED CALIBRATION & FACTORY RESET: Supports zero calibration and multi-point calibration for special materials or professional applications. Instant factory reset restores default settings at any time — useful after incorrect calibration or extended use.
- METAL SURFACES ONLY — CLEAR & HONEST LIMITATION: Designed exclusively for metal substrates (steel, iron, aluminum, copper). Not suitable for plastic, carbon fiber, or composite parts, preventing incorrect expectations and misuse.

## Questions & Answers

**Q: Can this gauge measure plastic or carbon fiber parts?**
A: No. CM-224 Auto is a paint thickness gauge for metal substrates only: steel/iron (Fe) and aluminum/copper (NFe). Plastic bumpers, carbon fiber, and composites cannot be measured correctly because they don’t support magnetic/eddy current testing.

**Q: What does Fe+Zn detection mean?**
A: Fe+Zn detects galvanized steel on ferrous panels. During used car inspection, compare symmetrical parts (left/right fender, doors, quarter panels). They should show the same material type. Different results may indicate a replaced or repaired panel.

**Q: Does the gauge require calibration before use?**
A: For automotive paint inspection, no calibration is required. Factory calibrated and ready after installing batteries. Detailed calibration may be needed only for high-precision industrial coating control (e.g., parts painting on a conveyor line).

**Q: Who is this gauge for?**
A: CM-224 Auto is ideal for used car buyers, vehicle appraisers, body shops, and detailing professionals. It helps quickly check paint thickness on metal panels to spot repainting, repairs, and uneven coating during inspections.

**Q: Is it suitable for outdoor use?**
A: Yes. CM-224 Auto operates from –20 °C to +40 °C (–4 °F to 104 °F), suitable for garages and outdoor car checks. It features temperature compensation for more stable readings during temperature changes. Keep the probe and surface clean.**
