[AT] Rust magic?

[JParks]

I am looking for any suggestions or recommendations for a real rust buster.

I have two sets of almost new TD6 track that sat on a machine for years and
all the joints were either really stiff or frozen.

I have soaked all the joints w/ diesel, driven over them several times with
wheel loaders and even a track loader.  I presoaked them again with diesel
and with the use of an excavator boom to hold each link down in sequence,
and using the curl linkage, I hooked up to each link and was able to work
each joint back and forth a little before moving down the chain to the next
link.  It is still too tight!

I talked to an old (like me) crawler man who has run a track shop for
decades (and he has "seen-it-all") and he does not think I should set them
on fire.  He has run across track like this before and he could not even
dismantle them without ruining or busting some of the individual links.

What liquid rust breaker on the market will really work (vs. what is simply
marketed and does not work)!?

Thanks for any help.
