So I opened the Dow Corning tube because "why not" and I figured I could leave some out and see if it would cure or not. All four tubes were solid.
Just because I could, I cut the tube off of the silicone and now have a solid tube of black silicone without the tube.
Returning the GE 2 and getting a tube of clear GE 1 and being done with it.
Thanks for letting me know what the worst case scenario would be with old silicone.
