So I was able to do a good compound on areas with etching and excess clear, while being gentle on the regions without much. All in all the car came out well. Review: Ease to use - Never used one of these before but this product was well designed, good directions, easy to understand how the device worked. Came with a small protective bag, wrist strap. Impressive, really recommend this product ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.7 out of 5 stars 87 Reviews | ## Images ![Paint Thickness Gauge CM-224 Auto – Digital Coating Thickness Meter for Cars and Automotive Inspection, Fe / Al / Fe+Zn Detection, 0.1 μm Resolution, Factory Calibrated, Large Backlit LCD - Image 1](https://m.media-amazon.com/images/I/61kHnWGHkTL.jpg) ## 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.** ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helped me detail better *by B***B on January 4, 2025* This helped me determine which areas of my car were high with clear coat and others that had less than the door jambs did!
