The tool shape matches the job.
- · Reach for a sponge or pad when the surface curves, flexes, or gets wet and rigid paper keeps fighting you.

Skip this form when

- · Leave it if you need dead-flat pressure across a broad panel; foam gives where you least want it to.
- · Leave it if the job is heavy stock removal — a firmer abrasive cuts faster and sulks less.
