Does anyone have experience with hand polishing stainless steel? I need to polish up a mod by hand. The curves don't allow for machine polishing and I don't own a Dremel. My drill has also grown legs so I'd prefer to do this by hand. Do you have any recommendations on what polish to use. What grit sandpaper - and where to find it? Or if you don't recommend sandpaper do you know what would be a better fit? Or even if you know where I can send something to be polished for a reasonable price. Thanks for help in advance!
