Them staples are hard. I used a combination of tools. First issue was to locate the holes. Then I used needle nose pliers to start the bend and a body dolly to prevent the staple from rotating with the pressure. Finished, with 2 pair of vise grips. 1 to hold the staple flush, and 1 to finish the bend. What I did do to keep the stable was a bit of 3M adhesive(black weather strip) on the back side. They won't move after that sets up. I was not expecting the staples to bee that stiff. The old ones were soft and came out rather easy.
