Help identify a "PASTE"

[Wicked Pete]

In my toolbox I have a tube of a paste type material with abrasive. The tube has no label or markings, and I am "running on empty".

The intended use is to "break-in" a tight fit. I used it on a new pistol (slide), got smooth and nice, after a trip to the range. I've heard you can smear a little on the bullets to loosen up the barrel; I never did that.

Now, I can't find it. Any ideas?

Lapping compound?

White lithium grease?

Edit: It should only be used in a light coat or it will turn into grime.

I have to agree with freonr22, your description is lacking.

Bore paste?

Sounds like lapping compound. It comes in many different grits. Clover is a common brand. You can find corse and fine at most autopart stores as it is used to lap in valves after grinding during a valve job.

The only abrasive compound I'd put on bullets EVER, is firearm specific "fire lapping" stuff. Tubbs and Wheeler make a kit through Midway. There was another player that was 2x the price, but don't see them offered anymore.
Wheeler kit

As for the rest of your description, Freon hit it first. (Valve) lapping compound.

JB's Bore Paste is my "go-to" for any other firearm fitting/smoothing/lapping duties. Mix with CLP to a thick honey consistency and you have what the S&W 642 guys use for slicking up their triggers!

There are several kinds of grinding compound and they come in different grit sizes, like sandpaper. Some will inbed in the metal and continue to cut. Some not so much. And some like the JB Bore paste mentioned above do not inbed and are the best for firearms. I would not recommend Silicon dioxide, valve grinding or Clover compound for firearms because it does imbed. Remember it is easy to remove metal... putting it back, not so much.

Hey thanks fellas. I believe we are hitting the nail on the head, JB Bore Paste sounds like it. Your comments about the "inbed" ring true.

[swifty]

JB typically comes in a small white tub with a black screw-on lid IIRC.

"Hydrated silica" = wet sand. I've used TP to hone shotgun chambers. I've read some Marlin guys use it in their actions to accelerate break in on lever guns. "With whitening" TP usually has more sand than normal kind.
