Re-siliconing an old tank?

Hey guys,
I had a few questions about the proper way to resilicone an old tank. I have a new to me 75 gallon tank which made it into a few pictures on here previously (link). The silicone between the glass panels is fine. However, the silicone around the internal portion of the tank has gotten beat up and scraped into by its former owner. As such I am uncomfortable with using the tank before I attempt to fix the silicone. However, I want to do this correctly and have a few questions.
1. Should I take the entire tank apart, risking breaking it, and resilicone everything?
2. Should I scrape out all the internal silicone, leaving the silicone between the glass completely untouched?
3. Should I do something else that I haven't thought of?
Additionally, those that have information on the proper bead width for the silicone on a 75 gallon tank, if you guys could pass that along I would greatly appreciate it.
Finally, please keep in mind that this is NOT a discussion about the type of silicone I plan to use. I am going to use Momentive 100 Series silicone. I have already purchased it and I believe that between its excellent material properties and its FDA certification it is a good choice. Considering a previous adventure (link) I have already learned the hard way about silicone selection... no need to rehash the subject here.
I hope others can learn from this post as well.
Thanks guys,
Jeremy
