 I'd say that if the tank is fine now, it should stay fine. I don't think chemicals hang around for a while and decide one day to leach (relative to this scenario).
As I mentioned, I used the GE II and had no problems, so I wouldn't now tear my tank apart to replace it 

Based on the rep stating that the formula changes, I probably wouldn't use it again, just in case. Silicone I and GE 1200 are both safe options, so I'll use those on future tanks.
