Just out of my own curiosity, and since 3M has a manufacturing plant in my state, I drove up there today to find an answer to the silicone paste question and how to remove it. Here is the email response I received when I got home.
Hi Mike,
I recommend using 3m General Purpose Adhesive Cleaner, 08984, to remove your silicone paste.
If you have any further questions/concerns, please don't hesitate to contact us.
Thank you,
Jared S
