Mike lambert- Good on you for not doing the wetsanding regardless of what the customers want.
And yeah, my last Mazda had spots that were under 3mils when new, only vehicle I`ve ever done the clearcoat-damage thing to, and that was with a PC using 3M PI-III Machine Glaze no less.
Rsurfer- I`ve had blends where the repaint`s texture was different from the OE, and based on the overlap areas it does indeed fill in/replace the OE texture. But IMO finding a shop that`s willing and able to do that kind of work (to a proper standard) would be a mighty tall order.
