What gives a pad it's destination(cutting, polishing, finishing)? I mean usually finishing pads are softer (less firm), and polishing pads are more firm? what gives the pad his attribute? it's firmness? or the pors in the sponge?
This is it. They are made in England. anyway, that's where they came along with my polisher (bought from ebay). I have another blue, and a wool bonnet.
Finishing pads are soft and not very dense. Cutting pads are dense and firm. Open-cell pads are often better at fast cutting IIRC. Wool pads are used for heavy cutting because the fibers themselves cause the pad to cut fast.
