I've been using PB Blaster penetrating oil with good success. Since you
know there are Penetrox particles (it is zinc dust plus castor oil per
the MSDS) between the tubes, I'd try to wick some PB in there, let it
sit for a while and then work it back and forth to loosen up the dried
up Pentrox. Repeat until the boom comes apart.
The Penetrox'd 3" booms here put together 7 years ago, came apart
easily, but at some point the oil evaporates away.

I need to separate KLH 3 inch aluminum boom sections. When assembled 20 years ago I used
Penetrox on them so hopefully they are not welded together. In fact one of them separated 1/2
inch then stuck. Would there be a “penetrating oil” that would help to
free/lubricate these joints to make the separation easier?
Thanks and 73,
