LPS 3 is good stuff, but the mfg only suggests it for storage up to 2 years indoors. Their words, not mine.

FWIW, price was only one consideration in my last post.

Bottom line is that it works for some of us. My buddy has used it for 1000's of Lugers for 65 years or so. It works for him and it works well for me.

There's more than one way to skin a cat, this one works for me for longer term storage. I also use LPS 3, Triflow, WD40 and others. There are many other good solutions as well.
