A paint thickness gauge for use in the detailing industry requires fine measuring resolution in increments of 0.1 mil (0.0001= inch) is typical. Therefore you should choose a paint gauge with a minimum 3% accuracy and a 0.1 mil (2 micron) measuring resolution.

An electronic paint thickness gauge 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.

Take readings on each panel left – right every 2- 4 inches, then drop down 2-inches and repeat. – Paint Thickness Template - http://s3.photobucket.com/albums/y88/TOG...n9br-3.jpg
