IF this was to be a gauge of of your paint depth I doubt they would be asking you to record your paint depth in MILS
1 mil = 1/1000 of an inch
most factory paint = 4 to 6 mils in depth
a far more accurate way of reading paint depth is MICRONS
1 micron = 1/1000 of a millimeter
in short a micron is much smaller than a mil and is therefore more accurate when allowing you to calculate the depth of clearcoat you are removing when you are going at it with a polisher!
here endeth the lesson in paint depth measurement... god I should moderate the detailing section... oh... hold on... i do!
