Screw rail with vinyl insert...
Are the screws in the rails beneath the vinyl inserts meant to have dicor or some type of sealer on them? I'm replacing my cracked vinyl inserts and noticed there is no sealer at al on the screws. The trim I'm replacing runs up the front of the TT to the first few horizontal feet of the roof. Seems odd that the screws wouldn't be sealed.
Here is a photo I pulled off the internet to illustrate the trim and type of screws I'm referring to.
