Oh my! Even lubricating is complex!! So, is it a coin toss for which to use??![]()
A dry engine seizes but you can get away with coin toss method on lightly torqued mod threads.
I used vaseline on aluminum tube mod threads w/o oxidation or galling issue.
Dry SS, brass and "silver" plated contacts work for a long time between cleanings.
Aluminum contacts need anti oxidation compound like noalox or ox-gard.
