Use it when
The fit is obvious.
- · Reach for the Norton Ultra Fine Sponge when the job is final surface prep, between top coats, and contoured surfaces: 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.

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.
