From a past post I made:
What does not survive cryo treatment well are:
1) Metal Oxide Varistor, an electronic component used in surge suppression [they cracked].
2) Silicone compounds for damping [they shrunk a bit and hardened].
3) Neoprene rubber [shrank a bit and lost elasticity]. I also have been told that silver mica caps don't do well, and "some" adhesives".
Add the mov's and silicon (and other) damping compounds last, *after* the cryogenic treatment....that way everything will be perfect.
