I have a nice shiny stainless steel mod that I want to be a nice brushed stainless steel mod. I tried scotch brite and it did little. My next attempt was a dremel tool with a wire brush that did little. Next the dremel with a small grinding stone. That took the smooth off but it is still shiny and you can see the marks from the stone. There is a sand blasting place in town and I could try that. I am sure someone has gone from shiny to brushed here and will tell me what they used. By the way it's an innokin cool fire 1 and an SVD.
