Default fiberglass mast question

Ed wrote:
Anyone have suggestions on a method I might try to "twist" and collapse
some sections of my telescoping fiberglass mast? I put it up several days
ago with perhaps a bit too much "vigor" in making sure it would not
collapse on its own and now that I want to stow it away there are a couple
of sections I can not unlock. My grip is good, but the sections are really
tight. I hate to use something mechanical for fear of cracking the
fiberglass and I hate to use a lubricant since the locking requires
friction.

Thoughts ?

Immerse outer end (only)in hot water. Hopefully it will expand slightly
,but not the inner mast part .

Alternatively cover outer end with insulation material and 'cool' inner
mast tube with evaporating CO2 'ice' hopefully causing it to shrink
slightly.

Of course success is not guaranteed but worth trying .....at least it is
non-destructive.
