I used Eternabond once and it worked great, but I did not care for the "black" strip over my painted roof radius. ...If you have a white roof radius then "white" Eternabond tape is a good permanent the solution that may not look "acceptable."
There is another thread I started on this subject, so I will post this update there as well:

UPDATE
I ordered a $10 roll of "LLPT Caulk Tape-Clear" on Amazon and tested it's adhesion on my car paint.
https://www.amazon.com/gp/product/B0...91CK8ZYM&psc=1
I am very impressed with it's thickness, clarity, grip, and the tape is almost unnoticeable when applied to a flat surface.
However, I have not tried it on my RV roof radius, because I don't pick-up my RV from storage until ~April-2021. So maybe someone else who is willing to try this $10-$20 solution ($20 for 2 rolls) can let us know how they make out?
My concern is that the roof channel will interfere with the adhesion of the tape? (TBD) ...And if this clear tape pulls off at some point then that's sort of rules this option out.
I also considered putting a bead of 100% silicon on top of the Geocel Proflex, to act as a UV barrier, but I have since learned that silicon has acidic properties that may breakdown the Proflex over time. (Unknown if it really does?)
So after much thought, I'm changing my position on what can be done to extend the life of our Proflex roof sealant -- by protecting it from UV damage? And I think using a can of Flex Pro Clear will work best. This stuff will add a clear rubber barrier that should look good and last. ...Just tape, spray, and peal off the tape away leaving the Flex Pro Clear only on top of the Proflex.
Now who is willing to be the first Gennie Pig? ...Or you you will have to wait for me to try Pro Flex-Clear in April/May 2021 and I will post another update then.
