I've tried countless methods to strip paint and rust from old metal projects, but these nylon abrasive discs are game-changers. The first time I used them on a crusty wheelbarrow tub, the thick paint practically jumped off—no gouging, just clean metal underneath. They're like magic erasers for grime!

The perforated design is genius. Unlike wire wheels that melt paint into a gummy mess, these stay cool and actually expose fresh abrasive as they wear down. I did an entire truck fender with less than one disc by letting the tool do the work—just gentle pressure and patience. The metal stayed warm, not scorching hot.

Two quirks though: They're hungry for wide surfaces but struggle in tight corners (keep a smaller tool handy). And yes, they wear faster than steel brushes—I went through 2.5 discs on that wheelbarrow—but at this price, who cares? Just buy extras.

Pro tip: Wear safety glasses! Those spinning fibers launch microscopic debris like confetti. I learned the hard way when my forearm looked like I'd wrestled a cactus after forgetting long sleeves. But for resurrecting flea-market finds or prepping welding projects? 10/10 would strip again.
