don't know if this is the best place to ask this. If I want to expose the brass on my RM2 what would be the best thing to use to do that? Would it be fine grain sand paper or is that too rough? Or something like super fine steel wool? What are other people using? I used super fine steel wool to remove some paint from another device & the metal had a nice brushed finish after I was done. Just not sure if it would work on this though.
