Yes they will scratch and/or remove metal depending on the grit, the amount of wear and how you use them. They are fantastic for certain things and way too aggressive for other things. If all you are trying to do is rough up the existing paint then I vote you not use flapper disks. If you are trying to take off all the paint down to bare metal then they are one way to do it but practice on something else first. An alternative that I like is the "Surface Conditioning Disks" by 3M and others that look kind of like plastic coral. These things are designed to remove paint but not take off metal. They come in different styles and there are ones made to mount to an angle grinder.
