RE: Installing new vinyl trim inserts, caulk or no caulk?
There is new butyl tape behind every piece of trim that was removed and replaced. And all new screws were used in the rebuild which is already complete. It doesn't make sense to back each screw out to add a dab of caulk and retighten them all. But thanks for the suggestion.

Installing new vinyl trim inserts, caulk or no caulk?
So I replaced/repaired my roof this summer on our hybrid travel trailer, and as part of that headache, I replaced some of my aluminum trim pieces along with all new white vinyl inserts and #10 screws. Obviously, the vinyl insert is NOT waterproof, but I have heard several folks mention that it waterproofs the trim and not to skip that step. In my opinion, the loose-fitting vinyl insert was never designed to be waterproof and is really just for aesthetics to hide the screw heads. During disassembly, I did find a lot of evidence of water that had gotten behind my old vinyl trim inserts. Subsequently, many of my trim screws were heavily rusted, which may be because of trapped water behind the vinyl trim. Just an assumption, but the water had to have been getting in somewhere to rust so many screws. I found two spots where the roof was leaking when I removed my old rubber roof but hard to say if that's what caused the trim screws to rust or perhaps water trapped behind the vinyl insert trim. So for installing new vinyl trim inserts, I've seen some YouTubers caulk both edges where the insert goes into the trim channel and was wondering what the school of thought is out there in the community. To caulk or not to caulk?
