I have an old Marlin 60 that was given to me by my uncle that is in pretty bad shape. I was wanting to Duracoat it, but have never done this before. I read on Duracoat's site that you should blast with aluminum oxide 120 grit, but I don't have the means of doing this. I also read that they can be sanded down by using 600 grit sand paper. Would this give me the same results? Any help would be greatly appreciated.
