Any suggestions for grinding discs? I was planning to some serious work on my car starting with the body. What do ya'll use? I have some ideas like this Smith & Arrow I'm really interested in. (http://stores.shop.ebay.com/smith-an...__W0QQ_armrsZ1). It's actually very cheap and has a lot of good feedback from 6000 sales. But if ya'll have any other in mind then that would be great also.
