Subject: [TN] Erase to abrade off HASL off circuit cards

We have a requirement to use an erase to remove solder from a PCB pad
down to the base copper. The recommended erase is too soft- we found a
hard grey abrasive erase that goes in an electric eraser but don't know
where we can buy more of these. Any ideas?
