    i thought PTG measures the paint thickness on top of the metal. Someone else is saying that it measures metal AND paint.

    If I'm not mistaken the more correct term for these instruments would be Coating Thickness Gauges. Thus they measure the amount of a coating over a metal either ferrous or non-ferrous. So I think it only measures the amount of paint.
