I wonder if acidic oils in fingerprints promote cold weld. One of my buds at work is one of those unfortunates who has to wipe all fingerprints off a firearm before putting it away, otherwise corrosion sets in and permanently etches fingerprints into the finish. I don't have that problem myself, fortunately and I wash my hands before handling components anyway, but I wonder if there's a correlation.

Don't be the darkness.

America will perish while those who should be standing guard are satisfying their lusts.
