Automotive Paint Detailing

Auto detailing is the practice of performing an extremely thorough cleaning, polishing and waxing of an automobile. DeFelsko manufactures various hand-held, non-destructive paint thickness gauges that are ideal for use in automotive paint detailing.


Auto Paint Thickness Meters - most auto paint thickness gauges work by sensing the distance between the sensor and the metal base material. That's total distance, which would be the thickness of all layers (primer, base, color, and clear coats) and any repainted material, etc. You have to take an educated guess as to how much each layer consists of.


An electronic auto paint thickness meter can be an invaluable tool, before buffing it's always a good idea to check the paint film thickness to see how much of the paint film thickness available, check is periodically during the process and on completion to see how much was removed. Take measurements with a paint and coating thickness gauge and mark them on a template so that you have a reading of before / after polishing.


Using an auto paint thickness gauge gives a professional detailer credibility and also acts as an insurance against 'break-though' of a clear coat, which would entail a re-paint and I suspect a very irate customer. Original paint has a better resale value than a re-painted vehicle, plus they will lose the use of their vehicle for some days. The ideal setup would be a PosiTest DFT Combo for the metals and a PosiTector 200 B/Adv for the composites.


If you use a car outline template and mark the paint thickness, you can advise the customer of any potential problems and you'll also have a permanent record of the customers paint surface, which can be used as a reference each time the car is polished.

Select substrate
F - for ferrous metals (steel and cast iron)
N - for non-ferrous metals (aluminum, copper, brass, etc.)
FN - for all metal substrates, gage automatically recognizes the substrate and takes measurement


PosiTest DFT meter - series of gauges measure coatings up to 40 mils (1000 microns) making them ideal for non-destructive measurement of automotive paint thickness on a variety of metals.

a) PosiTest DFT Ferrous is ideal for measurements on steel panels
b) PosiTest DFT Combo is available for measurement requirements on both steel and aluminum panels. With 3% accuracy and a 0.1 mil (2 micron) resolution
Either PosiTest DFT model provides the capability to measure the amount of paint removed while sanding and buffing.
