Curious what you folks are using for exterior caulking. I use dicor and eternabond tape where appropriate but what about some of those fine caulking lines that are on the roof and sidewall joints? ...
A number of manufactures use silicone and many RV techs do. Like one told me when doing some work on my RV and I freaked out about him using silicone. "Been doing it for years, works as well or better than anything else so why would I not use it". The part he siliconed was fine 5 years later when I sold the unit.
I would not hesitate using it on openings on the sides but not sure about a roof.
