Interesting, thanks for the explanation. Are you sure that it was rust coming out of the bore, and not copper/powder fouling reacting with the humidity and heat?
Good ole dark redish orange rust, not the normal blue and grey from powder/copper. As I said, I do think it helped, but it didn't waterproof it.
I agree with Gasman on melonite. Thinking about it for the blued rigs I do keep that don't have Ck. CK is good stuff, but it does wear off and scratch rather easily on a rig that's not babied.
