You will be sanding a long time with 600 if they have any depth to them. I would start with 320 with a hard backer. If they are too deep you may cause more damage than good. If you keep sanding, even with a hard backer you will create long waves that will make it look odd.
Sometimes your better off to just leave it go. I've never seen sparks eat into stainless like it does glass but not saying it couldn't be a possibility.
Maybe a cutting torch throwing molten metal?
