The mesh is tough as nails with a high tear resistance, so it won't fall to bits on you, even when you're getting into those tight spots. You'll get a perfect finish without any scratches, which means no rework. And here's the best bit: you don't have to muck around lining up holes. Just slap it on the pad and you're good to go.
It's spot on for sanding plaster and fillers anything that kicks up a lot of dust.
