Panel at a time in straight lines. Work it till it is gone, this way the abbrassives break down, it starts of aggressive and breaks down to a finishing polish. You need to press hard and work it as it wont do anything other wise. Its hard work mind.
To get more even pressure use a folded terry towel rather than hand foam pad. There shouldnt be much residue to remove if you have worked it long and hard enough, what is left should wipe away easily with a towel.
Dont be afraid of working it, its not like T cut, or other cutting compounds that are really harsh, this starts of cutting and dimishes down to a finishing polish to make sure it does not insert more marks than it removes.
