Review on LotFancy Stripping Disc 6PCS: Quick and Easy Paint and Rust Remover for Angle Grinder – Versatile Silicon Carbide Abrasive Wheel for Wood, Metal, and Fiberglass – Black by Bob Larson

They hold up as well or better than most. My favorite use for removing paint, powder coating and mill scale. They do it faster than a flapper and barely scratch the metal underneath. They won't last long if they fit over an edge with a radius greater than 1/8 inch, or even a freshly cut edge with a small protruding burr. This will clean the MIG weld well until you get to the next result. lead to an inferior weld with well-adhered spatter, then the spatter will crack the pane. Don't cry like a wolf just because you gave it a pepper and immediately destroyed it. You should be gentle, stroking the disc whenever possible.
