When working on a tank the rule of thumb is clean it, clean it, clean it, clean it again, wipe it down with alcohol, clean it, wipe it down with alcohol again, then start thinking about cutting open the tube of silicone.
Remove the trim, then use guitar string to cut the old seam. Then scrape the residual silicone off the glass (not a time to be lazy, or say good enough). Then its time to clean and start reassembling.
