I got ahold of some 3m cubitron II discs. They were advertised as "hookit2"; It does not hook to regular hook and loop; and I can't seem to find any backing pads that it hooks to. Does anyone know about this stuff? The cubitron discs I have from before, have hook and loop, that sticks to the pads and backer system I already have. I got them from Taylor toolworks, but they only pointed me to the discs that 3m sells for body work.
