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.
