This stuff was designed for use with firearms but makes everything else work better, too. I got an old crockpot and am using the "dip everything" method but it was impressive how nice the various tools I'm using to fish the parts out have become. My thought is that if I can feel a difference it the operation of some pliers it should be making a heck of a difference with guns. Heck, I even took apart my rusty old reloader for a dip and the darn thing came out showroom new! Whenever I get a new hand tool or mechanical part I'll be dipping that thing before it ever gets used - like I did with the Ruger LC9 and SR9c. It's the only way to go!
