The only fix recommended by the CPSC is the COPALUM high pressure crimp
which is very expensive to have done if you can even find the required
trained electrician with the necessary crimp tool.
The recommendation to use one of the 3M wirenuts is the from the
engineer who did extensive tests for the CPSC, as is the wirenut process
in your link below. None of this has been endorsed by the CPSC, but it
is based on the only extensive testing of aluminum branch circuit
connections I am aware of.

You may have a lot of trouble finding one. There are likely
very-few-to-none familiar with the wirenut process at your link above.
And using the recommended 3M wirenut instead of the UL listed purple
wirenut may be a problem for an electrician or inspector.
