I must say, this tip has allowed me to separate an A3S boom that has been
stuck since I took it down two years ago. I had tried heavy application
of penetrating silicone libricants and lots of pressure, but no luck.
The heat/cooling cycle suggested loosened the joint up enough that I
could take it apart myself. Amazing.

I put up the A3S 7 years ago before I knew about Noalox. When I moved, I
had to carry the boom intact, as I couldn't separate it, even with help.
