My friend works on a vintage schooner in Seattle. They used marine grease on some turnbuckles and other parts, but surprisingly it didn't hold up well. Regular grease did better. Which may be to say that marine grease does better when sealed into some threads, less so when exposed. I noted the same on some headsets where I used marine grease. It started to dry out much sooner than I thought it would. I now use SuperLube, which I think has teflon in it. Good stuff. And of course in the end, just service your bearings every so often when the grease gets old.
