I knew I hated water borne for a reason! AHA!
Just kidding of course.
Barry, I wouldn't use that stuff on my guns unless I was watching and
wiping the whole time to make sure there was no pitting on my
equipment. Sadly, the nickel content and the quality of chrome on the
guns we buy isn't all that great. If you are talking specifically
about the gun block, it has a really high nickel content to keep away
rust, but is susceptible to other chemicals. Any of the hard cast
aluminum parts (the gun bodies) will be scarred for sure with most
The last time I had some "stuff" dry up and gunk my gun block as well
as back up inside the gun (it's a long, ugly story) it was a dried
resin of several different materials before I caught it. I though the
gun was plugged with bad material... it was that bad.
Anyway, after trying all the things I was confident in using, I went
to this plan.
Take the gun apart and break it into pieces of the gun block, the
trigger assembly, springs, collars, needles, etc. In a stainless
steel soup pot, put all the affected components in a soup pot full
of water and bring it to the smallest simmer you can. Leave the
pieces in for an hour (or more as needed) after the water starts to
simmer again. Of course if you see the resins floating off, fish out
the pieces and start cleaning. It seems the resins fail all at once,
and they will come off in pieces. After after another thirty minutes
or so (and some good toothpick work) you should able to clean up all
the resins off the gun parts.
It wasn't anything other than the high, consistent heat over a long
period of time that made the resins come apart.
I actually got the idea from a guy that took off some knife scales on
a home made knife. He epoxied them on, and messed them up in the
final shaping of the handle. One of the knife makers on the forum got
a chuckle and told him to put it in the oven for a few hours at 200F,
then take it out and pop the scales off. Apparently, it worked like
So I figured... water boils at 212F... enamels, lacquers, varnishes,
etc., are nothing but modified resins, so why not? Best part? No
pitting, discoloration or possible damage to the guns. (Mine was a
Finex knockoff, but still expensive enough!).
As always, just my 0.02.
