PB Blaster for lube?

I know it's great on old rusted stuff. They include guns as one of its "countless applications."

Anyone using it for lube? Revolver or auto?

I love the stuff, but I would not put it on a gun unless the slide were rusted solid to the frame and I needed to break it free It is not something I would use to lubricate anything that usually required oil or grease.

Who in their right mind would put PB Blaster on a gun?

Oh yeah, the same folks that think WD40 and duct tape are God's two greatest gifts to humanity.

PB Blaster is a horrible penetrating oil. Much better products out there.

Is it so hard to just go buy a bottle of real gun oil?

PB Blaster is an OK penetrating oil, not as good as Kroil, but much
better availability.

It is NOT a lubricant. If you want a cheap lubricant for your guns,
go buy a quart of Mobil 1 synthetic 5W-30 motor oil. I shoot a lot,
and I'm still working on a quart I bought at least 6 years ago.

I never wanted to mention it here but i see more and more people willing to use motor oil in there guns like I do. Motor oil has gone though massive amounts of research and testing under much worse conditions than a gun will normally see. Last winter my Keltech PF9 that I no longer own was struggling in the sub zero temps. I lubed it with royal purple 5-W20 oil and it ran like a champ. I have not shot anything much this winter but have been concerning motor oil more and more lately.

PB blaster, like Liquid Wrench, are very thin oils specifically designed to flow & wick into tight places, like the threads on a rusted bolt. If that is what you need done, great but not for general gun use.

FWIW...

As has been said, PB is for breaking stuff loose. My experience differs from Bill's in that I have had better success with it that Kroil, but I don't wanna start a mechanic's version of a caliber war here...

Anyway, to those who use motor oil: How does it perform for repelling dirt? I have just started using Slip 2000 EWL on my revolver and am impressed that it doesn't pick up environmental crud like Rem Oil loves to do.

And why 5W? It seems that something a little heavier would be better for guns, as its role is more as a light grease than a flowing lubricant.

A 50/50 mix of acetone and ATF is better then either!!!!

Thanks guys.

I'm going to try synthetic Mobil 1, after I search some more and decide on which weight.

I'd mixed up some 3-part (Dextron III/ kerosene, mineral spirits) Ed's Red for cleaning, and was happy with the results. Ed also lists a 2-part (50/50 ATF/kero) as a ER compatible lube, but I can't hack the odor of the kero. In fact, I used Hoppe's #9 after cleaning with ER, to get rid of the kero smell.

I was also thinking of moly grease (engine assembly lube) and found a bunch of guys like a product called Lubriplate.

Problem with using motor oil is all the additives in it, they are toxic and can absorb through your skin... but it is a good lubricant otherwise.

PB Blaster might help remove rust spots... but there are other products that would work for this.

I have been using industrial grade oil and aluminum grease designed for use on food handling factory equipment. So it is food safe, and designed to work in high moisture, acid, salt, and other harsh conditions. It works very well.

I am around enough deadly chemicals at work... I am looking to switch to biodegradable cleaners too. Lower my exposure a little at least.

Motor oil- 30W or lighter before firing, 90W after firing. Lube and preserve.

I wouldn't use penetrating oil on anything that relies on a primer for ignition. Your favorite brand of gun oil is plenty cheep enough, and won't foul your ammo.

Okay, are we arguing about how PBlaster smells, whether it is a good penetrant...or are we answering the original question?

I have PBlaster and use a fair bit of it...on rusted fasteners. Works great for me.

I have never had a reason to use it on a gun, and unless I find that Rossi I threw in a lake back in 1984 (old story, well documented, no illegal activity) I won't be using it on any guns in the future.
