To remove Orange Peel, you will need a pad that is somewhat hard, flat and less polish absorbent. Reason to it is because Orange Peel are “Hills” of the clear coat and it can only be “shaved” off from top down. If the pads were soft, it will somewhat “hug” the “hills” and “shave” uniformly down. So the “hills” will still remain as “hills”.
Foam Disc 2000 is made of denim which are of hard, flat and less pores material to hold most of the abrasives on the surface and compound away orange peel and other deeper defects.
