Don't rush into the name. You'll know it's the one when you hear it. Also, imagine calling the CG with the name you choose. I actually saw a boat named Mayday. What was he thinking, or not.
I think the only place for silicone on a boat is around glass or some plastics that aren't compatible with anything else. Since that area has silicone on it, it has contaminated everything it was on, so now nothing will stick to it. You'll have to grind down to some new material to reseal.
