I'd seal everything. If you go turtle you'll wish you had.
4200 is removable, I've used it plenty in the past. 5200 is a bear.Like I said before, your just sealing not bonding so either would probably be fine. I just feel better using an overpriced product that was made for that application, and it seems to hold up well. I rarely use silicone because it seems to peel off rather quickly.
