Thanks for the info Norm.

I wonder if I could use wet auto body type sandpaper in 600,800,1000 grit?

Norm,
I used "Brasso" copper,chrome&metal polish with a dremel toll at 6000 RPM's. Turned out pretty good,it's shining real nice!

Thanks for the tip!!-Only one thing left to do;replace the firing pin spring with a Wolf's,maybe.

Norm, thanks on the Brownels reference for the white polishing compound. We used to buy all our gunsmithing tools from them. I did smooth out a MSGs M-4 carbine with valve grinding compound from the motorpool. We used to soak our buffer heads in water to keep them from overheating. I will polish my feed ramp and inner chamber but not remove any metal. Carbon buildup is a bitch. Our M-16s used to lock up due to the bad ammunition. Sgt P.

I did a polish job on my P64 to stop a random failure to go into battery problem - worked great so far.

After polishing, does anything other than normal lubrication have to be done to protect the metal. Looks like bare metal would have a tendancy to rust.

I just use regular Polishing Compound to a mirror surface and clean it, then lube it well with Break Free and let it soak into the pores of the metal to inhibit corrosion.

Yes it will, and I was just coming here to post this. Unless it is a LAST RESORT - DO NOT POLISH THINGS THAT ARE COATED JUST BECAUSE. The feed ramp on the P64 is coated like the rest of the gun. When polishing, you are removing that coating, and very likely even adding surface area (due to small scratches and pits from polishing) which will promote rust more than just removing the coating.

Not a single device in the history of mankind has damaged more good weapons than a "tool" with a Dremmel in his hand.

If you remove the coating, you just committed to paying special attention to keeping it lubed or you'll end off worse than you were before.

Did you get a rusty ramp?

The ramps aren't coated, they're blued. And some of the ones I've seen have had visible machining marks on them. They fed alright, but could definitely use a polish. I don't think you're adding surface area by polishing smooth a roughly machine piece of metal.
Still, this is the only area on the gun that I'd polish.

Dick,
I believe even if you buff the burrs or nicks out the feed ramp, you can always reblue it. Correct? As that is what is hanging up the bottom tips of the bullets as they have a tendancy to hang up. We did polish the match grade .45s that we had if they were not cleaned up by our armorers. Caspian did polish up a few of our special order barrels feed ramps cause one of our guys worked for them off duty. Sgt P.
