So much better and faster then clay bars, thats for sure! On harder clears I did not get any hazing, but on a solid black Porsche...well do a test spot, something I never did and noticed that
the car looked trashed, and then I had done half the car.
One Porsche I did the paint was so rough to touch at and after 15 minutes with the Autoscrub pad the paint was so smooth. Use plenty of lubrication; your regular QD should be enough.
