Why??

My prefs . . .

3M 5200 Fast Cure for adhesive strength, and for long EternaBond runs, I use EternaCaulk along both sides of the tape. Totally prevents tape from coming up.

Interesting, was not even aware Eternabond made caulk!
I know their tape is very well regarded in the RV world.

Once something is contaminated with silicone, nothing will ever stick again. Not even new silicone will stick to old silicone.

BINGO! When I work on the RV, I always assume that I will have to re-do or patch it another time, in the future. Nothing sticks to silicone, even more silicone. If you used silicone you will spend hours with different solvents trying to remove every last vestige of the old silicone, and still probably won't get it all. I always look to the future and try to make it easier on myself, if I can.

I have had no issue removing old silicone that has lost its adhesion, clean surface with alcohol and applying Geocell. I have done this on quite a few older rigs and even my new Triton I am currently repairing some seals that were done with Silicone. Once the Geocell sets up its not comming off.
