Went and got the attachment, glue all gone in 20 minutes.
Just be careful, keep the pad moving across the glue, RPM low, <3000, and low pressure. Patience with this thing does get rewarded.
After removing the glue, I sloshed a liberal amount of Acetone over the de-glued area and wiped it dry to even out the colour variations.
I did apply a bit too much pressure in one area and it quickly wore through the coloured surface to the cloth below - didn't matter as it was a wear patch and can be replaced.
