BTW, I would not reseal or add more caulk if it's not needed. Caulk on top of sound caulk does no good at all and just makes the job of reworking it later that much harder. I would not dig out good caulk either unless there's overall problems and you are doing it all.
I used Geocel for my front cap trim. Thats what the MFG used.

Everyone goes right over Dicor self leveling caulk when re-caulking roof items. Every video I've ever seen on roof caulking shows them cleaning the original then applying another layer over it.
