rac polisher

The Cables too short and the Motor burns out really quickly. Mine lasted one pollishing session.

apart from that its really good!!

No, the machine you have is a buffer, not a polisher. It is fine for buffing off product residues (although I would still prefer to do this by hand), but it is not up to the task of polishing as per the linked intructional thread. This is because polishing requires the use of foam pads, not microfibre bonnets. The foam is necessary to work the polishes hard enough and greak the abrasives down - using microfibre would result in a sub standard finish, as the products wouldn't be worked properly.
