b. Strip off all the old tape and then apply EternaBond? (if so what to use to dissolve through the sticky glue?
c. squirt some compound into the crack and call it good.
Is there something else besides EternaBond?
Lastly - it looks like there's more than just tape on this old installation. Is it common to smear on a glue compound as well as the tape?
Thanks. Please see the picture to clarify what I'm talking about.
T hank you.

Don't try to patch it up, this is now the appropriate time to do the following normal task that needs to get done every decade of so.
Scrape off all the external goo. Remove screws, carefully pry/lift off the vent. Scrape off the old mounting tape between the vent and the
fiberglass body. Plexiglass scrapers work well for removing the excess adhesives. Clean the surfaces, put new Butyl rubber tape against the
fiberglass, Reinstall the vent using new stainless steel screws of the appropriate size. If you wish to do a belt and suspenders approach you can also apply a roofing compound around the lower edge and over the tops of the screw heads. All these products are available from your local RV store or from online sources.
