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 use Sikaflex myself. My Home Despot carry's it.
Even I used coulks professionally, I yet have to find one that last on RV. Boat coulk hold well, but turned yellow after 1 year.
I've been using polyurethane roofing caulk on other jobs as black doesn't match RV and it is good stuff, forming rubber-like after drying and with good adhesion.
Lately found white version at HD sold as window caulk, but my experience with it just started.
For roof coating the $200/bucket white stuff at HD looks very good and comes with lifetime warranty.
Still thinking who's life it is.
