So, I took the Dreadnought out to the range the other day and got to put a few shells through it. Got it home and wanted to take it down, clean it and put a new sling plate onto it (Christmas gift). I get it apart and just about everything on the inside has rust on it. Got the inside of the receiver and magazine tube cleaned up along with the bolt and magazine spring, but the interior of the magazine tube extension still has a lot of rust in it.

I've been using a 12ga bore brush on the drill and hosing it down with WD40, but it doesn't seem to do much if anything at all. Earlier tonight I filled the tube with WD40 with the intention of letting it sit for a few days, see if that doesn't help out.

So, anyone have any magic cures for rust on a parkerized finish?

Try to 0000 steel wool and WD40 or 3n1 oil.  It will get the rust but not the pits.  I've not seen it hurt the finish but I've only used hand pressure, not a spinning drill.

I would get the gun refinished with a moly-teflon coating.  Then it won't rust anymore.  Where are you storing it?  Do you need a dehumidifier in your safe?   I use silica gel packs (very large ones) in my safe and never had any rust issues.

Thanks M1A4ME, I'll try the Steel Wool.


CovertChannels The gun lives in the safe inside the house, have never had any problems with anything else rusting in there. Thinkin this was maybe not oiled well (on the insides) after it was parkerized as the exterior has been fine. The gun was just refinished (parkerized) about four months ago. There shouldn't be any problems with rust at this point in time. If I'm not able to get the rust out, Inimagine it'll have to be blasted again to get it out. I don't really care for those other kinds of finishes and think if it was on this gun, I'd just have rusting under the sprayed on finish.

Parkerizing itself is not a good rust preventative.  What parkerizing does is create a porous surface that holds oil and grease which protects the metal.  If the gun wasn't well oiled after parkerizing, it is still prone to rust.  I technique I've heard of but haven't tried personally is to coat newly parked parts in vasaline and then gently heat them to soak it in to the parkerizing.  I would think that would work well.  If you want to go another route, parkerizing (un-oiled of course) makes a GREAT base for a sprayed on finish like Dura-coat.
