I read a ton of stuff on here where Scotch Brite pads, discs, etc are used on projects. Obviously, 95% of you know what they other person is talking about. I don't. For those of you who use them and love them, can you post a pic (from your shop or just a general picture from Google) of what you use and what you use it for? I was reading a thread today about rust removal and someone mentioned using red pad with CLR, another guy recommended gray pads and someone else talked about a purple disc on a grinder. I'd just like to see what they look like and what you use them for so I can get them without grabbing the wrong thing or walking around not knowing what to look for. Thanks.
