Thanks for the advice. Can anyone tell me what the lumpy ugly whitish blackish material that the POS used previously to seal the vent might have been?

I hate to say it but that ugly whitish blackish material is probably old Dicor which is what most are recommending. It can get dirty, but most people are not looking at your roof anyway.
At any rate you needed it sealed right now and it is sealed. It will hopefully (probably will) last for the trip and then you can deal with it when you get back. Here's your basic options at least based on the group condenses of this forum.
Peel the silicone up. Clean the residue as best as you can. Maybe try some of this stuff.
Link Apply Dicor to seal the cracks.
Peel the silicone and Dicor up and clean with acetone. reapply with Dicor.
Buy a 50 foot roll of 6 inch wide Eternabond tape and tape right over the old caulking.
Peel the silicone and Dicor up and clean with acetone. Buy a 50 foot roll of 4 inch wide Eternabond tape and seal the roof.
