My Tacoma is about 3 to 4 mils. It varies by location, based on the overlap from the robots that paint the vehicle.
I have checked other vehicles from other manufacturers and this seems to be typical. I'm sure there are exceptions, however.
Just to clarify, 3 to 4 mils is 0.003" to 0.004". As a reference, a typical business card is 10 mils or 0.010". So a business card is about three times thicker than your paint is.
In that 3 to 4 mils is the primer, sealer, basecoat and clearcoat. My GUESS is that the clearcoat is about 1 mil thick, but let me stress again that this is my guess
A repaint is typically thicker, because it's hard to compete with the efficiency of a robot. So, measuring paint thickness is an excellent way to tell if repair works has been done. 5-10 mils usually means a repaint, but this does vary my manufacturer so you need to take multiple readings to figure out the situation. When you get significantly over 10 mils you are talking Bondo (a filler) and that can be a problem if the work was not done well and it is really thick.
Before you get too excited about getting one of these, realize that they are VERY expensive. Mine was $700 and it was hard to justify the expense even in the business I am in. But it is a fun toy and there is no substitute for it.
