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.
You probably have a local weld supply store near you. Airgas comes to mind. Go in there and ask for the scothbrite pads for a grinder. They look like a scotchbrite but they are round and 4.5 inches in diameter. There is a velcro like backer that you can get also to attache the pad to the grinder. The pads are around $2.50 each and the backer is around $15.00 There are three different pads each with different coarseness. Red is low, brown is medium and I can't remember the coarsest color. I use red.
This is great stuff for getting rid of old paint and rust without damaging the metal. Use this alot on my cars. Drivers door:
OR, head on down to the local Janitorial supply house, they have them for floor maintenence machines, BIGGER! trim to any size or shape, and they are double thick, at least 5 levels of abrasiveness, from polishing (grey) to wax removal (black) green is perfect for filtering the wort on my home brew.
Here are the 7" diameter ones I use with an angle grinder, brown is coarse, purple is medium and green fine. They make the in 6" x 9" sheets to be used by hand also.

Harbor freight has a similar disc in 4" & 4.5" for about 5.00 Fasten all should carry something also similar. Your local weldind house should Cary them too. Good chance your local body shop supply house has them. If I needed one , I wouldn't think Napa or auto zone
Thanks to all who responded, my dad picked some up today and is going to give them a try on a '49 Olds we've been working on.
