You use them on glass first to break them in as the " scratchiness" for want of a better word, is at its height. Breaking it in on the glass softens this down and it's better to do it on the glass rather than the paint, where you would get marring. With the clay mitts you can really hear the good it's doing to your car. When you first start you can hear the contaminants being picked up but as you go back and forth over the panel, the noise decreases as the mitt does its job.
Yes when I used my clay mitt I could feel the surface imperfections gradually (very quickly actually) disappear completely, bonus is the mitt is so easy to use and very little chance of dropping it on the drive and ruining the thing, unlike the claybars I have used in the past.
Do the manufacturers recommend this glass breaking in procedure?
