Here is a great topic to be added to the tech section on Jemsite. I've read a couple posts here and on the old site pertaining to this.
Here is how I do it and what you will need.
Needed:
1. A pair of vise grips, or similar locking pliers.
2. A dust rag or old T-shirt.
3. A Dremel or similar tool.
4. A small brass wire brush. Go to your local WallMart and get them. They are part of a metal polishing kit.
5. Black acrilyc paint. Aleen's works well and can be purchased at said WallMart
6. Hopies gun oil. Again, WallMart.
7. The allen(hex) wrench to remove the pole pieces. Or a screwdriver, depending.
How to:
1. With the
allen wrench(screwdriver), remove the pole piece.
2. Using the vice grips and dust rag, lock the pole pice so that it is stable but not so tight that it mashes the threads. Use the rag to protect the threatds from the plier jaws.
3. Using the Dremel on the lowest speed, proceed to remove the rust from the pole piece. Don't use any more pressure than is needed to remove the gunk. Let the tool do the work and try hard to keep it steady.
4. Depending on how bad the pole piece was, you may find that the original finish has come of. Here is where the paint comes in handy. Don't dilute the paint. Use it full strength and dab it on. Set aside to dry.
5. If, when done, the original finish is fine, use the gun oil to coat the top 1/8" of the pole piece. Set aside to let the oil penitrate while you remove the next pole piece.
I have used this method before and have had excellent results.
