I just got a vintage genco to learn how to hone with and I need to clean it up a bit as well. There are several mild rust spots on the blade that I would like to try sanding off with my dremel. Can some one give me some tips on how to do this? Would I use a flap wheel? if so what grit would you recomend? Also, what chemicals do people use to help remove rust? I've read a lot about maas on here but I'm under the impression that it is just a polish and not a rust remover, us that correct? Thanks! Dave
