Corner Trim Removal and Reseal

[Ctgriffi]

I'm in the process of pulling off all of the roof-to-wall corner trim on the Warrior, cleaning everything really well and resealing with a long, continuous piece of corner-tape and the original trim, to keep things tight and dry for years to come. At some point in the last 34 years, somebody decided to heap huge amounts of gray sealant all over the trim (with a smattering of white bathroom caulk, sheesh)—I guess it's done the trick, but it's ugly as sin and I'd like to make sure everything is decent underneath the original "repair."

Each side of the coach has three different trim sections—the front and rear are the typical aluminum corner trim that fits the coach profile and is screwed in place, with a vinyl insert strip to finish it off. But there is also this center section (seen in the photo) which is different and just has a number of stainless screws through the top, holding it down. What's the best practice for this center section, to seal it well and have a decent, professional appearance? Do I need to cover each screw head with a big fat dollop of sealant, or can I just shoot some into each hole, before driving the screws? The original screws look like a #8 3/4" pan-head but I'd like to replace with slightly longer, for more bite—yea or nay?
