Does all the old butyl tape need to come off?
Getting ready to leave on vacation tomorrow and noticed the vent in the cabover was leaking. I stuck eternabond tape over the old butyl tape as I was advised it was alright, but it didn't stick proper...

I had issues with Eteranabond on my Fleetwood where PO slapped it over damage and the thing not sticking all the way around - created water pockets that directed water into the cracks.
My Lance on other hand - had very heavy layer of butyl tape all around. It looks ugly as the butyl overflows the joint and I am scraping it when it forms droplets, but the joints don't leak.
I don't see any aging on butyl, so if the old one is clean, I would just add more tape on top and squeeze the excess out.
Also Lance roof had some kind of liquid paste applied around roof opening, that forms 2" wide stripes over each trim. .
I could not find what is it, but it is holding very well.
Have no idea if this is how Lance sealed the camper at the factory, or PO redid it, but on 16 yo camper the only water intrusion was via slide awning screws, where they "forgot" to apply any sealant.
