    Rust on a Powder measure

    I have two that had a film of rust on them I took them apart clean all the rust off they are working smooth but clean dry metal needs protection. What is the suggested oil or coating to use to keep the rust away.

    I am thinking JPW to protect the metal but unsure and would a dry lube prevent rust ? yea I should know but I like some input.

    I'll agree and endorse Shawlerbrook's suggestion! I had a similar challenge as you experienced vis rust, and used a felt bob on a Dremel to get rid of it. Actually, it appeared that the bit of oxidation (rust) worked as a polishing compound, too, as I ended up with almost-mirror like surfaces. I applied a wax product marketed by Flitz, Click image for larger version.

    Hornady One Shot has worked well for all my reloading equipment.

    I keep oil away from the drums on powder measures.

    A good wax that doesn't contain abrasives is the way to go.

    Why not treat the source, not the symptom?
    Get a good dehumidifier.

    A good coat of automotive wax should work. I have used Silicon spray with good results.

    Depends on which parts of the powder measure you want protected. I wouldn't want anything on the drum or in the reservoir that would affect powder or cause it to clog/clump. I have used "museum wax" on some tools, but not with anything dealing with powder. One thought is a plastic bag with a desiccant, at least until you find a permanent method. Or if the drum and ID are rusting, perhaps drop a desiccant bag in the reservoir and replace the top to keep the innards dry (don't ferget to take the bag out afore dumping powder).....

    On the outside I would use Hornady one shot it dries to a waxy film , have always used graphite on the inside of measures.

    Graphite is a fine dry lubricant but it will not prevent rust.
    The OP's issue isn't lubrication, it's rust prevention.

    You should start with cold bluing, then some of the other things mentioned,if needed.

    Wax it like ya would a car when its out on the bench being used.

    As humid as it is there, you might have to oil and pack it away like a Iron mold when not in use.
    Everyone can learn from their mistakes.
    However; it's less painful, and cheaper to learn from the mistakes of others.

    Old age and treachery will always overcome youth, and skill.

    OK folks. Enough of this idle chit chat. This ain't no retirement home.
    EVERYONE!!

    I like to keep mine clean and dry with just a light dusting of Graphite powder (like locksmiths use) as lubricant.

    I keep mine in the HVAC in the house and haven't had a problem with rusting.

    Look at Johnson's paste furniture wax in the yellow can it is what I use on table saw and joiner tables it is slick and will prevent rust if applied often enough.

    I just checked my stash in my shop. The wax I have is "Renaissance" micro-crystilline wax polish. Aka museum wax. I have used it on knives' blades and tools that don't get used often.
