Didn't Think Much of These - Screws Under Vinyl Insert Trim

I pulled all that vinyl off, backed the screws half-way out(there are scores of them)sealed the exposed threads with a tiny eternabond strip, tightened screws and reinstalled vinyl. A previous trailer had some delamination from the screws wicking water along the threads so this was my solution. Going on six years on this stored outdoors trailer and so far so good.
