If you are a professional detailer and regularly machine polish a wide variety of vehicles whose history you cannot be sure about (e.g. is the paint original or has the car been resprayed in the past, has the car been subject to accident repairs in the past, how many times has the paint been heavily compounded in the past, etc), the DeFelsko PosiTest DFT Paint Thickness Gauge could be one of the best investments you will ever make, as it will allow you to accurately assess how much paint you have to work with and how much you remove as you polish (we are still regularly shocked by the number of detailers we come across who claim to be able to tell how thick paint finishes are by feel or eye alone - this is simply not humanly possible). As a result it serves as a form of safety net that will enable you to make an informed decision about how best to proceed in terms of machine polishing the car in front of you, which is critical given that most public liability insurance policies do not actually cover the vehicle being worked upon. In our studio, we use our own DeFelsko PosiTest DFT Paint Thickness Gauge on a daily basis to quickly and efficiently assess our work and the condition of vehicles that are being booked in for details. It is a robust and faultlessly performing tool that we simply could not be without.
The DeFelsko PosiTest DFT Paint Thickness Gauge is ready for use straight out of the box and powers on automatically when placed on the surface to be measured. Measurements are taken almost instantly (in either microns or mils, selected with the touch of a button) and there is no need to wait between making repeated measurements. The combined magnetic-induction and eddy current sensor measures paint thickness on all metals, including steel and aluminium, making it ideal for use on performance vehicles with lightweight metal panels. The sensor automatically recognises the base metal and takes corrected readings accurate to within +/- 2 microns (which equates to approximately +/- 2 % on typical factory paint finishes). The gauge features a large, easy to read display that automatically switches off when not used for more than 30 seconds and is fully weatherproof. It comes with a formal certificate of calibration and the calibration itself can easily be checked with the thickness shims supplied in the case, or reset completely if necessary. The gauge is supplied with a hard shell storage case, plastic calibration shims, AAA battery, full instructions and a two year return to base warranty.
The DeFelsko PosiTest DFT Paint Thickness Gauge is ready for use straight out of the box and powers on automatically when placed on surfaces to be measured. You should always ensure that the gauge is held perfectly flush to the surfaces being measured, as failure to do this will result in erroneous readings being taken. It is quite normal for automotive paint to vary in thickness between different makes and models of car, from car to car, between adjacent panels and even across individual panels, and for these reasons it is always important to take numerous readings in order to get a proper feel for the average paint depth on the particular car you are working on. As a rule of thumb we recommend making a minimum of 20-30 readings per panel, increasing beyond this in cases where unexpectedly low or high readings are obtained that are indicative of heavy compounding or accident repairs having been performed in the past. In terms of our own experience, it took many months of taking readings on a wide variety of different cars before we were able to piece together a mental framework of what to expect on different makes and models of cars in terms of average paint thickness and likely paint removal rates with various pad and polish combinations. Caution should obviously be exercised whenever gaining such experience.
