I second conductive grease. Got some from electrical switchboard people I work with.

Had two parts that were stuck together from back in Aberdeen this spring and now three that are stuck together. Is there something that’s supposed to go on the threads prior to assembly to prevent this? And is there any way to disassemble these things without destroying them in the process? I would like to think that this is an all weather operation around here but looks like rain has bad effects on any use of these MS mast sections.
