Yeah, the guy at the gun show had a similar display--electric drill running underwater in a fish bowl.
I bought a small (2 fl. oz.) spray bottle, about $5. Haven't gotten to try it yet.
In retrospect, I have my doubts that it will clean better than Ed's Red or Hoppes, of which I have a good supply.
Pretty sure nothing will touch Eezox in corrosion prevention, because nothing has so far.
I don't own an electric powered .45acp, so...maybe PT Barnum was right after all.
In the mean time, maybe I'll spray down all my electric tools and do a rain dance.
Oh well, it's only five bucks. I've paid a lot more and gotten a lot less.
