Use it when

The fit is obvious.

· Reach for the 3M Sanding Sponge Coarse/Medium when the job is rough shaping, drywall mud, and paint stripping: that is the fight it was built for.
· Aluminum oxide is the reliable one: cheap, tough, no surprises and no complaints. It will outlast your patience before it outlasts the job.
· This is the working middle: enough bite to matter, refined enough to leave the job somewhere worth continuing.

Skip it when

The job asks for something else.

· Leave it if you are actually solving a different stage of the climb than the one this pick was chosen for.
· Leave it if longevity and cut speed matter more than the price: cheap abrasive is cheap for reasons you feel on the tenth sheet.
· Leave it if you need dead-flat pressure across a broad panel; foam gives where you least want it to.

Best for

Where it earns its keep.

· rough shaping
· drywall mud
· paint stripping
· contour sanding

Buyer questions

The practical questions.

What is the 3M Sanding Sponge Coarse/Medium actually good at?

Coarse on one side for the first pass, medium when the surface starts to give way. Goes everywhere sheet sandpaper can't. In short: it earns its keep on rough shaping, drywall mud, and paint stripping.

Is 60-120 the right grit lane for this?

It sits closest to 40 grit, 60 grit, 80 grit, 100 grit, and 120 grit. This is a cutting stage, not a finish stage. Use it to remove material, not to fake smoothness.
