I replaced all the screws in the molding holding down the rubber roof with stainless steel screws dipped in 3M5200.
Well, most of them were rusty so you were right to replace them with SS. Some rigs last longer, depends on climate.
3M5200 is overkill for sure. You could've used 3M4200. Or even a $3 exterior polyurethane sealant from Home Depot. 3M4200 is a polyurethane sealant as well. They call 4200 "fast cure", but from my experience it dries at least as long as an exterior urethane caulk, though, being less dense, it flows easier. So it can leak off a vertical surface if you put too much. But you only need to dip the stem into it. Roof sealant commonly used in RV like Dicor or Geocel would also do, if you happen to have a tub laying around.
