Trewax vs. Oil
When a fellow in the forum insisted that Trewax was best for protecting guns, I had to check it out. I procured a sample, which I used on some guns and reloading gear.

What I found was odd. Lots of reloading gear is blued steel, which rusts after being handled, in this humid heat. Oddly, Trewax didn't offer much protection. They still rusted, seemingly faster with the wax applied. Perhaps I didn't clean them well, and salts from my skin remained under the wax.

It did well on my guns, but didn't seem to last much (if any) longer than a coat of good oil. It works best on glossy blues, not so well on matte finishes. Uncoated areas adjacent to coated areas seemed more likely to rust than they would otherwise.

I'll stick with a quality oil, myself.
