The detailer spray, or even diluted carwash, is more of a lubrication to help avoid the clay sticking to the painted surface rather than a wet and dry type abrasive system. You only apply very light pressure and can feel the difference almost imediately. I even got my better half to compare the bit of the bonnet I had just done to the door panel next to it! As i said, very satisfying results.

As far as I am aware the clay is not an abrasive as such and there is no need to polish afterwards but it does promote easier polishing/waxing because the surface is smoother and the polish or wax applies more easily.
