Not me, man. I won't use one. I have some scratches in the paint that I am pretty much certain came from the blade. Not FROM the blade itself, but likely something picked up and dragged across the surface. Of course, I guess a micro fiber towel could do the same thing, I suppose.....
But yeah, it works great for the windows.
Honestly, though, most of my drying is done with the leaf blower these days anyway...
