"A good example of this is at the ends of the quarter panels were we found depths of 7mm due to end of spray patern."
Just to offer some clarification...1 mil = .001"...or one-thousandth of an inch. Coating thickness is typically measured in mils which should not be confused with millimeters (mm). 7mm would be the equivalent of .276"...or more than 1/4".
However, I do agree with Paul's overall and I use 3.5-4.0 mils as a target nominal. Due to spray patterns, I've see upwards of 6 mils and anything over 6.0 mils is cause for further scrutiny.
