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 3000 is made of corduroy which are similar to denim but slightly softer to cater for soft/sticky OEM paint. The polishing abrasives will be held onto the pad’s surface and compound away orange peel and other deeper defects.
