Oh, wait, were you referring to the ScotchBrite buffing pads? They're
great for derusting minor surface rust. I use them with WD-40 then
wipe all that crud off. I can stick those directly to the velcro hooks
on the bottom of my ROS, but usually just do it by hand. Nitrile
gloves hold up best for that.

This is the sort of thing:

I bought one just to see what it is good for. They do not seem to make them
for 4.5" angle grinders (low rpm). I use it in a cordless drill.
