I have some Stainless Steel pieces (several feet in length) that currently have a brushed finish. I want to buff / polish these to a mirror finish. I have a new bench grinder, but I have no experiece with buffing wheels and compounds. Due to the amount of material, I would prefer to do as little by hand (sandpaper) as possible, but I ultimately want a nice end result. What products (stitched wheel, felt wheel, firmness of either, compounds, etc) do I need to accomplish this? I have tried some buffing, but many of the deeper original scratches remain.
Any details on procedures and products would be greatly appreciated.
Thanks
