Hydraulic and engine oil has to be replenished just before start up and removed after shut down because it reverts to a waxy / solid state at room temperature.
Oh, I'm not talking about restoring one to operational condition. The problems you mention were only due to the neccessity to withstand extreme heat. Airshow passes wouldn't involve M3+ flight. Tank sealants, oil etc, would not need to withstand high temps, therefore alternatives could be used (and have been in the past). A restored SR-71 wouldn't even need to use JP-7, as J-58's could happily drink JP-4 or 5 (limiting the aircraft to M1.5).
