I'm looking for some tips on how to keep my dies from rusting. I have a set of Lee carbide dies for 9mm and a set of RCBS carbide dies for 308. Both sets of dies were almost comlpletely covered in surface rust after about two weeks of owning them. I have tried literally drenching them in Ballistol, Rem oil, WD40, wax, etc. You name it, I've tried it. I even reapply every day and they still rust. They are in my basement right next to a big dehumidifier that runs round the clock. I live in Missouri where it is fairly humid but it is not particularly humid in my basement. This was a dry summer too. While the rust is purely cosmetic at this point, I don't want it to get worse and affect the function of the dies. So, does anyone have any tips?
