This stuff goes under various names. "Diamond Dust Cloth" "Abrasive Cloth" "Duracut Abrasive Cloth" "Duracut Abrasive Cloth"etc.
Also called "aluminum-oxide" cloth
In the pic it's the dark roll on the left:
Made , or distributed by 3M, I used to get it from Curtis Industries Part * 89224, (180 grit) but since they pulled the local sales force, it's more difficult to get.
The stuff isn't cheap , but to me it's worth every penny.
None of the auto parts stores in my area carry it, not even napa , even
though they have a host of 3-m products. They must have only a selective line. Even my auto-electric suppliers have a difficult time coming up with it.
Can you tell me a good source for it?
Thanks!
